Notes on plug-in hybrids

▌Notes on plug-in hybrid operation

WARNING Risk of chemical burns and poi-

soning from damaged high-voltage battery

If the housing of the high-voltage battery has

been damaged, electrolyte and gases may

leak out.

Avoid contact with the skin, eyes or

clothing.

Immediately rinse electrolyte splashes

o with water and seek medical atten-

tion straight away.

DANGER Risk of re and explosion from

excessive internal pressure of the high-

voltage battery

In the event of a vehicle re, ammable gas

can escape and ignite.

Stop the charging process immediately

in case of unusual odours, smoke or

burn marks.

Leave the danger zone immediately.

Secure the danger zone at a sucient

distance.

Call the re service.

The hybrid system combines a combustion engine

with an electric motor.

Characteristics when the vehicle is at a standstill:

The combustion engine is generally switched

o.

Idle speed occurs only in certain instances.

Characteristics when starting the vehicle:

If the high-voltage battery is suciently

charged, the vehicle can be started with the

electric drive without the combustion engine

(noiseless start).

If the high-voltage battery for the electric drive

is not suciently charged or the vehicle condi-

tions for a silent start are not met, the vehicle

will start with the combustion engine.

Depending on the system, it may be that even

though the high-voltage battery is charged,

electric mode has restricted or no availability.

When the combustion engine has run for long

enough and the ambient conditions permit,

electric mode will be available without restric-

tion once more.

To start the combustion engine, the high-volt-

age battery can be used as a starter battery.

Characteristics with moderate power output

requests:

The combustion engine is switched o as

oen as possible during a journey.

Depending on the drive program selected and

the state of charge of the high-voltage battery,

the vehicle can be accelerated electrically up

to a speed of approximately 140 km/h.

Characteristics with high power output requests:

The electric motor supports the combustion

engine (boost eect), e.g. when pulling away

or accelerating.

244

Driving and parking

F247 0074 02

The high-voltage battery is discharging.

Characteristics when releasing the accelerator

pedal during a journey:

The electric motor is operated as an alternator

when in overrun mode and during braking.

The high-voltage battery is charging.

Notes on electric mode:

Vehicles with hybrid systems generate signi-

cantly less noise when stationary and when

being driven than vehicles with combustion

engines.

In electric mode, the vehicle may not be heard

by other road users due to the signicantly

reduced noise generated.

It is for this reason that the vehicle is equip-

ped with a sound generator, which serves as

an acoustic vehicle alerting system (AVAS).

This safety system is prescribed by law.

The external noise produced by the sound

generator is perceptible in the vehicle interior

at low speeds and does not constitute a mal-

function.

If not all of the vehicle conditions for electric

mode are met, then the combustion engine is

switched on.

Performance restrictions in electric mode are

possible as a result of the operating tempera-

ture of the high-voltage battery and drive sys-

tem, the ambient temperature and ageing of

the high-voltage battery.

In electric mode, the maximum power will not

be permanently available and may drop to

continuous output.

Notes on the acoustic vehicle alerting system:

The sound generator produces speed-depend-

ent driving noises up to a speed of approx-

imately 30 km/h when driving forwards and

reversing.

This helps other road users, particularly

pedestrians and cyclists, to hear your vehicle

better.

From a speed of 20 km/h, the acoustic vehi-

cle alerting system gradually switches o.

The sound generator is o when the vehicle is

stationary.

▌Manually disconnecting the high-voltage on-

board electrical system

DANGER Risk of death and re due to

modied and/or damaged components of

the high-voltage on-board electrical sys-

tem

The vehicle's high-voltage on-board electrical

system is under high voltage. If you modify

component parts in the vehicle's high-voltage

on-board electrical system or touch damaged

component parts, you may be electrocuted. In

addition, modied and/or damaged compo-

nents may cause a re.

In the event of an accident or impact to the

underbody, components of the high-voltage

on-board electrical system may be damaged

although the damage is not visible.

Never make any modications to the

high-voltage on-board electrical system.

Do not switch on or use the vehicle if its

high-voltage on-board electrical system

Running-in notes

To preserve the engine during the rst 1500 km:

Drive at varying road speeds and engine

speeds.

No faster than 140 km/h.

Drive the vehicle in drive mode A or ;.

Shi to the next higher gear at the very latest

when the needle reaches the last third before

the red area in the rev counter.

Do not shi down manually in order to brake.

Avoid overstraining the vehicle, e.g. driving at

full throttle.

Do not depress the accelerator pedal past the

pressure point (kickdown).

Only increase the engine speed gradually and

accelerate the vehicle to full speed aer

1500 km.

This also applies when the engine or parts of the

drivetrain have been replaced.

Please also observe the following running-in

notes:

In certain handling and driving safety systems,

the sensors adjust automatically while a cer-

tain distance is being driven aer the vehicle

has been delivered or aer repairs. Full sys-

tem eectiveness is only reached when this

teaching-in process has concluded.

Brake pads, brake disks and tyres that are

either new or have been replaced only achieve

optimum braking eect and grip aer driving

several hundred kilometres. Compensate the

reduced braking eect by applying greater

force to the brake pedal.

Engine output and engine torque (Mercedes-AMG

vehicles)

The actual (maximum) values that can be ach-

ieved for engine output and engine torque

may deviate from the certied values within

the permissible tolerances according to coun-

try-specic guidelines (basis: UN-ECE No. 85

or country-specic guidelines).

engine torque will be available to you.

Notes on driving

WARNING Risk of accident due to objects

in the driver's footwell

Objects in the driver's footwell may impede

pedal travel or block a depressed pedal.

This will jeopardise the operating and road

safety of the vehicle.

Stow all objects in the vehicle securely

so that they cannot get into the driver's

footwell.

Make sure that there is always sucient

clearance for the pedals.

Always t the oor mats securely and as

prescribed.

Do not use loose oor mats and do not

place oor mats on top of one another.

WARNING Risk of accident due to incor-

rect footwear

Incorrect footwear includes, for example:

shoes with platform soles

shoes with high heels

slippers

There is a risk of an accident.

Always wear suitable footwear so that

you can operate the pedals safely.

WARNING Risk of accident if the vehicle is

switched o while driving

If you switch o the vehicle while driving,

safety functions are restricted or no longer

available.

This may aect the power steering system and

the brake force boosting, for example.

You will need to use considerably more force

to steer and brake, for example.

Do not switch o the vehicle while driv-

ing.

DANGER Risk of fatal injuries due to

exhaust gases

Combustion engines emit poisonous exhaust

gases such as carbon monoxide. Breathing in

these exhaust gases is hazardous to health

and results in poisoning.

Never leave the engine and, if present,

the stationary heater, running in an

enclosed space without sucient venti-

lation.

Driving and parking

253

F247 0074 02

WARNING Risk of skidding and of an acci-

dent due to shiing down on slippery road

surfaces

If you shi down on slippery road surfaces to

increase the engine braking eect, the drive

wheels may lose traction.

Do not shi down on slippery road surfa-

ces to increase the engine braking

eect.

DANGER Risk of fatal injury due to poison-

ous exhaust gases

If the tailpipe is blocked or sucient ventila-

tion is not possible, poisonous exhaust gases

such as carbon monoxide may enter the vehi-

cle. This is the case, for example, if the vehicle

gets stuck in the snow.

Keep the tailpipe and the area around

the vehicle free from snow when the

engine or the stationary heater is run-

ning.

Open a window on the side of the vehicle

facing away from the wind to ensure an

adequate supply of fresh air.

WARNING Risk of accident due to the

brake system overheating

If you leave your foot on the brake pedal when

driving, the brake system may overheat.

This increases the braking distance and the

brake system can even fail.

Never use the brake pedal as a footrest.

Do not depress the brake pedal and the

accelerator pedal at the same time while

driving.

NOTE Engine damage due to excessively

high engine speeds

The engine will be damaged if you drive with

the engine in the overrevving range.

Do not drive with the engine in the over-

revving range.

NOTE Causing wear to the brake linings by

permanently depressing the brake pedal

Do not permanently depress the brake

pedal while driving.

To use braking eect of the engine, shi

to a lower gear in good time.

NOTE Damage to the drivetrain and

engine when pulling away

Do not warm up the engine while the

vehicle is stationary. Pull away immedi-

ately.

Avoid high engine speeds and driving at

full throttle until the engine has reached

its operating temperature.

NOTE Damage to the catalytic converter

due to non-combusted fuel

The engine is not running smoothly and is mis-

ring.

Non-combusted fuel may get into the catalytic

converter.

254

Driving and parking

F247 0074 02

Only depress the accelerator pedal

slightly.

Have the cause rectied immediately at

a qualied specialist workshop.

NOTE Reduced battery life due to frequent

short-distance trips

The 12 V battery may not be suciently

charged when the vehicle is used only for

short-distance trips. This reduces the life of

the battery.

Drive longer distances regularly to

charge the battery.

NOTE Vehicle damage due to failure to

observe the maximum permissible clear-

ance height

If the vehicle height exceeds the maximum

permissible clearance height, the roof and

other vehicle parts may be damaged.

Please observe the indicated maximum

clearance height.

If the vehicle exceeds the permissible

clearance height, do not drive in.

Take the modied vehicle height in the

case of roof superstructures or other

carrier systems into account.

Please bear in mind that all the speed values

stated in this Owner's Manual are approxi-

mate and are subject to a certain tolerance.

Notes on driving with a roof load, trailer or fully

laden vehicle

When driving with a laden roof luggage rack or

trailer and with a fully laden or fully occupied vehi-

cle the handling and steering characteristics of

your vehicle change.

Therefore observe the following notes:

Do not exceed permissible roof load and

trailer load. Also observe the information in

the technical data.

Distribute the roof load and vehicle load

evenly and place heavy objects towards the

bottom. Also observe the notes on loading the

vehicle in this regard (/ page 186).

Drive carefully, avoid abrupt moving o, brak-

ing and steering and fast cornering.

Notes on driving on salt-strewn roads

The braking eect is limited on salt-strewn road

surfaces.

Therefore, observe the following notes:

Due to salt build-up on the brake disks and

brake pads, the braking distance can increase

considerably or result in one-sided braking.

Maintain a much greater safety distance to the

vehicle travelling ahead.

Remove salt build-up as follows:

Brake occasionally, paying attention to the

trac conditions

Carefully press the brake pedal at the end of

the journey and when starting the next jour-

ney

Notes on aquaplaning

F247 0074 02

Observe the following notes during heavy rainfall

or in conditions in which aquaplaning may occur:

Reduce speed

Avoid tyre ruts.

Avoid sudden steering movements.

Brake carefully

Also observe the notes on regularly checking

wheels and tyres (/ page 30).

Notes on driving through water on the road

Water ingress can damage the engine, electrics

and transmission.

Water can also enter the air intake of the engine

and cause engine damage.

Observe the following if you must drive through

water:

The water, when calm, may reach no higher

than the lower edge of the vehicle body.

Drive at a walking pace at most; water can

otherwise enter the vehicle interior or engine

compartment.

Vehicles travelling ahead, or oncoming vehi-

cles, can create waves which may exceed the

maximum permissible depth of the water.

The braking eect of the brakes is reduced aer

fording. Brake carefully, paying attention to the

trac conditions until braking power has been

fully restored.

Notes on o-road driving

WARNING Risk of accident if you do not

keep to line of fall on inclines

If you drive at an angle or turn on an incline,

the vehicle could slip sideways, tip and roll-

over.

Always drive on inclines in the line of fall

(straight up or down) and do not turn.

WARNING Risk of re due to ammable

material coming into contact with hot

parts of the exhaust system

If combustible materials, e.g. leaves, grass or

twigs, come into contact with hot parts of the

exhaust system, they may ignite.

Driving o-road places greater demands on your

vehicle than driving on normal roads. Check the

entire vehicle for damage and foreign bodies

every time aer driving o-road. Foreign bodies in

the wheels or powertrain can lead to imbalances

and therefore vibrations.

If the F driving mode is active: select

another driving mode.

Deactivate DSR.

Apply the brakes to dry them aer fording.

Check that the service brake is working nor-

mally aer a long downhill stretch.

ECO display function

Depending on the model and equipment, your

vehicle will have one of the following repre-

sentations of the ECO display.

The ECO display summarises your driving charac-

teristics from the start of the journey to its com-

pletion and assists you in achieving the most eco-

nomical driving style.

The ECO display assesses the following criteria for

an economical driving style:

Coasting at the right times

Consistent speed

Moderate acceleration

The lettering in the segment will light up brightly,

the outer edge will light up and the segment will

ll up when the following driving style is adopted:

1 Steady speed

2 Gentle deceleration and rolling

3 Moderate acceleration

The lettering in the segment will be grey, the outer

edge will be dark and the segment will empty

when the following driving style is adopted:

1 Fluctuations in speed

2 Heavy braking

3 Sporty acceleration

The ECO display will show you when you have

driven economically:

The three segments will ll up completely at

the same time

The edges around all three segments will light

The additional range achieved as a result of your

driving style in comparison with a driver with a

very sporty driving style will be shown in the

centre of display

4. The range displayed does

not indicate a xed reduction in consumption.

Driving and parking

261

F247 0074 02

The ECO display shows an evaluation of your driv-

ing style on the driver's display depending on the

situation. This enables you to check the eciency

of your driving style and adjust it if necessary. The

ECO display menu shows a ball 2 that will roll

forwards or backwards on a stylised road in the

direction of travel according to the driving charac-

teristics.

Above and below the road, lines mark the area for

an ecient driving style

3. Ball 2 will light up in

green if it is rolling within these lines. Outside the

lines, the ball will light up in orange.

The overall assessment of your driving style "from

start" is indicated using stars

1. It starts with

ve empty stars, which you can ll one aer the

other if you drive eciently. When all ve stars are

lled, a glow will appear in the background.

You can call up the ECO display function via

the

Classic menu (/ page 404).

ECO Assist function (vehicles with 48 V on-board

electrical system)

For plug-in hybrids, note the ECO Assist informa-

tion (/ page 265).

ECO Assist is active only in drive pro-

grams ; and A.

ECO Assist analyses data for the vehicle's expec-

ted route. This allows the system to optimally

adjust the driving style for the route ahead, save

fuel and recuperate. If the system detects an

event ahead and the vehicle nears the event, ECO

Assist will calculate the optimum speed for maxi-

mum fuel economy and recuperative energy

based on the distance, speed and downhill gradi-

ent.

If the deceleration provided by ECO Assist is not

sucient, you must also brake with the service

brake. This will be the case particularly if, for

example, you pull away again in slow-moving traf-

c and the distance to the vehicle in front is very

short.

"Foot o the accelerator" recommendation

Route event ahead

If a route event or vehicle that requires an adjust-

ment of your driving style for more eciency is

detected ahead, corresponding symbol

2 and

the ý symbol (grey) will be displayed.

If you release the accelerator pedal, the ý

symbol will turn green and recuperation in over-

run mode will be initiated. If the deceleration is

262

Driving and parking

F247 0074 02

not sucient, also apply the service brake. If ECO

Assist intervenes for a route event ahead (not for

a vehicle in front) and you then press the acceler-

ator pedal again, you will end control by ECO

Assist.

The ECO Assist display will be hidden again in the

following cases:

You do not react to the ECO Assist recommen-

dation for a long time.

You depress the accelerator pedal while ECO

Assist is intervening for a route event ahead

(not for a vehicle in front).

ECO Assist cannot identify any further recom-

mendations from the route ahead.

Depending on equipment, ECO Assist will detect

following route events

2 in addition to the vehi-

cle in front ¥:

Roundabout

T-junction

Downhill gradient

Speed limit

In drive program A, ECO Assist will react

only to the "vehicle in front" route event with-

out displaying the ¥ route event or ý

recommendation.

System limits

If the calculated route is adhered to when route

guidance is active, ECO Assist will operate with

greater accuracy. The basic function is also availa-

ble without active route guidance. Not all informa-

tion and trac situations can be foreseen. The

quality depends on the map data.

ECO Assist is only an aid. The driver is responsible

for keeping a safe distance from the vehicle in

front, for vehicle speed and for braking in good

time.

The system may be impaired or may not function

in the following situations:

If visibility is poor, e.g. due to insucient illu-

mination of the road, highly variable shade

conditions, rain, snow, fog or heavy spray.

If there is glare, e.g. from oncoming trac,

direct sunlight or reections.

If the windscreen is dirty in the vicinity of the

multifunction camera.

If the multifunction camera is misted up, dam-

aged or obscured.

If road signs are hard to detect, e.g. due to

dirt, snow or insucient lighting, or because

they are obscured.

If the information in the navigation system's

digital map is incorrect or out of date.

If signs are ambiguous, e.g. road signs in road-

works or in adjacent lanes.

If the radar sensors are dirty or obscured.

When you drive on roads with steep gradients.

If there are narrow vehicles in front, such as

bicycles or motorcycles.

Recuperative brake system (plug-in hybrid)

▌Function of the recuperative brake system

The function is only available for plug-in

hybrids.

Depending on the selected recuperation level, the

electric motor is operated as an alternator when

Driving and parking

263

F247 0074 02

in overrun mode and during braking in order to

charge the high-voltage battery while driving. As

soon as you take your foot o the accelerator

pedal when the vehicle is in motion and in trans-

mission position h, recuperation in overrun

mode is initiated.

The higher the recuperation, the more sharply the

vehicle is braked when coasting and the more

electrical energy is fed into the high-voltage bat-

tery.

The deceleration in overrun mode may not be suf-

cient depending on the driving conditions. Decel-

erating to a standstill is not possible. Also brake

with the service brake if necessary. Always adapt

your speed to the driving conditions and keep a

sucient distance.

The recuperative brake system has the following

characteristics:

supports braking with electronically controlled

brake force boosting

converts the kinetic energy of the vehicle into

electric energy

If you brake hard, the mechanical brake is

also used. This means that the maximum

recuperative energy cannot be recovered. The

more you accelerate and brake in an anticipa-

tory manner, the more eciently energy can

be recuperated.

System limits

The braking eect of the electric motor during

recuperation in overrun mode may be reduced or

may not be available at all in the following situa-

tions:

when the high-voltage battery charge level

increases

if the high-voltage battery is not yet at a nor-

mal operating temperature

In these cases, the desired deceleration is set by

the brake control system.

▌Manually setting recuperative deceleration

This function is only available for a plug-in

hybrid.

You can use the steering wheel gearshi pad-

dles to adjust the intensity of recuperation in

drive programs n, o and Î.

The following recuperation levels are available:

hÃ Intelligent and anticipatory recupera-

tion with ECO Assist (/ page 265)

hq No recuperation: the vehicle rolls freely

h Normal recuperation

h± Increased recuperation: strong deceler-

ation in overrun mode, e.g. for driving on

downhill gradients

264

ahead, corresponding symbol 2 and the ý

symbol will be displayed in grey.

If you release the accelerator pedal, the ý

symbol will turn green and recuperation in over-

run mode will be initiated. If the deceleration is

not sucient, also apply the service brake.

If ECO Assist intervenes for a route event ahead

and you press the accelerator pedal, you will end

control by ECO Assist. This does not apply in the

case of a vehicle in front.

The ECO Assist display will be hidden again in the

following cases:

You do not react to the ECO Assist recommen-

dation for a long time.

You press the accelerator pedal while ECO

Assist is intervening because of a route event

ahead. This does not apply in the case of a

vehicle in front.

ECO Assist cannot identify any further recom-

mendations from the route ahead.

In addition to a vehicle in front ¥, ECO Assist

can detect the following route events

Function of 4MATIC

4MATIC ensures that all four wheels are driven.

Together with ESP

and 4ETS, 4MATIC improves

the traction of your vehicle whenever a driven

wheel spins due to insucient traction.

You can display the current distribution of drive

torque to all four wheels on the head-up display

and in the right-hand display area of the driver's

display. The fuller the respective scale, the higher

the corresponding drive torque.

If you fail to adapt your driving style, 4MATIC can

neither reduce the risk of an accident nor override

the laws of physics. 4MATIC cannot take account

of road, weather and trac conditions. 4MATIC is

only an aid. You are responsible in particular for

maintaining a safe distance from the vehicle in

front, for vehicle speed, for braking in good time

and for staying in lane.

In wintry road conditions, the maximum eect

of 4MATIC can be achieved only if you use

winter tyres (M+S tyres), with snow chains if

necessary.

NOTE High-voltage battery damage due to

leaving the vehicle idle for lengthy periods

of time

Lithium-ion batteries experience a natural self-

discharge.

Exhaustive discharging can therefore occur if

the vehicle is idle for several months. This can

damage the high-voltage battery.

Driving and parking

291

F247 0074 02

To avoid damage, please observe the fol-

lowing recommendations when handling

the high-voltage battery.

NOTE Accelerated ageing of the high-volt-

age battery due to not observing the fol-

lowing recommendations

As a result of its basic characteristics, the

storage capacity of and the amount of energy

available from the high-voltage battery decrea-

ses over the course of its life. Due to this, both

the maximum electrical range that can be ach-

ieved by the vehicle and its maximum electri-

cal output can be impaired.

The following factors could accelerate the age-

ing of the high-voltage battery:

a high level of charge, especially if the

vehicle is idle for a lengthy period of time

frequent rapid charging with direct current

(mode 4)

leaving the vehicle idle for lengthy periods

at high ambient temperatures

To avoid accelerated ageing, please

observe the following recommendations

when handling the high-voltage battery.

NOTE Damage to the drive system when

charging the high-voltage battery at

extreme altitudes

The drive system may be damaged if the high-

voltage battery is charged at elevations

greater than 4,000 m above sea level.

It may then no longer be possible to continue

the journey.

Avoid charging processes at extreme

altitudes.

Recommendations when handling the high-voltage

battery:

Rapid-charge the high-voltage battery with

direct current (Mode 4) only when required.

In case of longer downtimes, switch o the

vehicle with a charge status of the high-volt-

age battery between 25 % and 30 %. Do not

permanently connect the high-voltage battery

to a power supply.

If leaving the vehicle idle for lengthy periods,

avoid high outside temperatures wherever

possible.

Every six weeks check the charge level of the

high-voltage battery (/ page 309).

Make sure to charge the high-voltage battery if

the charge level is below 15 %.

Do not disconnect the 12 V battery even if the

vehicle is le unused for a lengthy period. Oth-

erwise the condition of the vehicle's high-volt-

age battery cannot be monitored.

When only using the high-voltage battery with

low states of charge, fully charge the high-volt-

age battery twice a year.

Depending on the charging version, your vehicle is

equipped with one of the following vehicle sock-

ets:

Type 2 for charging with alternating current

(mode 2/3)

292

Driving and parking

F247 0074 02

Type Combo 2 for charging with alternating

current (mode 2/3) and charging with direct

current (mode 4)

Example: type Combo 2 vehicle socket

AC charging port type 2

Socket extension for DC charging

When using a CCS charging cable (Combined

Charging System) for charging with direct cur-

rent at a vehicle socket type Combo, both

ports on the vehicle socket 1 and 2 are

used for charging.

Charging options for the high-voltage battery

(mode 2, 3 or 4):

While the vehicle is in motion by means of

recuperation

Stationary alternating current charging:

At a mains socket (mode 2)

at a wallbox or charging station (mode 3)

Stationary DC charging (vehicles with vehicle

socket type Combo 2):

At a rapid-charging station (mode 4)

Depending on the country-specic vehicle equip-

ment and your vehicle's charging cable, single

phase AC charging is also possible.

Observe the dierent grid requirements of your

current location when charging. Only use charging

cables which conform to the grid requirements.

Consult a qualied electrician or your local grid

operator if you have any questions.

It is recommended that you charge the high-volt-

age battery at a wallbox or charging station due to

the improved charging performance and better

charging eciency oered.

System limits

The power output of the high-voltage battery may

be impaired by the following:

high or low outside temperatures

Electrical auxiliary consumers in the vehicle

being switched on, e.g. operating the air con-

ditioning system

extended periods without charging

The charging time or the charging power of the

high-voltage battery may be increased by the fol-

lowing:

Driving and driving safety systems

Driving systems and your responsibility

Your vehicle is equipped with driving systems

which assist you in driving, parking and manoeu-

vring the vehicle. The driving systems are only

aids. They are not a substitute for you paying

attention to your surroundings and do not relieve

you of your responsibility pertaining to road trac

law. The driver is always responsible for maintain-

ing a safe distance to the vehicle in front, for vehi-

cle speed, for braking in good time and for staying

in lane. Pay attention to the trac conditions at

all times and intervene when necessary. Be aware

of the limitations regarding the safe use of these

systems.

Driving systems can neither reduce the risk of

accident if you fail to adapt your driving style nor

override the laws of physics. They cannot always

take into account road, weather or trac condi-

tions.

Some driving systems can regulate or limit the

speed to a previously set value. Draw atten-

tion to the stored speed when changing driv-

ers.

Information on vehicle sensors and cameras

Some driving and driving safety systems use cam-

eras as well as radar or ultrasonic sensors to

monitor the area in front of, behind or next to the

vehicle.

WARNING Risk of accident due to restric-

ted detection performance of vehicle sen-

sors and cameras

If the area around vehicle sensors or cameras

is covered, damaged or dirty, certain driving

and safety systems cannot function correctly.

There is a risk of an accident.

Keep the area around vehicle sensors or

cameras clear of any obstructions and

clean.

Have damage to the bumper, radiator

grille or stone chipping in the area of the

front and rear windows repaired at a

qualied specialist workshop.

Particularly, keep the areas around the sensors

and cameras free of dirt, ice or slush

(/ page 589). The sensors and cameras must

not be covered and the detection ranges around

them must be kept free. Do not attach additional

licence plate brackets, advertisements, stickers,

foils or foils to protect against stone chippings in

the detection range of the sensors and cameras.

Make sure there are no overhanging loads pro-

truding into the detection range.

If there is damage to a bumper or the radiator

grille, or aer an impact, have the function of the

sensors checked at a qualied specialist work-

shop. Have damage or stone chipping in the area

of the cameras on the front and rear windows

repaired at a qualied specialist workshop.

The reversing camera can extend and retract

automatically for the purpose of calibration,

even though there is no camera image in the

display.

Function of ABS

The Anti-lock Brake System (ABS) regulates the

brake pressure in critical driving situations:

During braking, for instance, at maximum full-

stop braking or if there is insucient tyre trac-

tion, the wheels are prevented from locking.

Vehicle steerability while braking is ensured.

If ABS intervenes when braking, you will feel a

pulsing in the brake pedal. The pulsating brake

pedal can be an indication of hazardous road con-

ditions and can serve as a reminder to take extra

care while driving.

System limits

ABS is active from speeds of approximately

5 km/h.

Driving and parking

323

F247 0074 02

ABS may be impaired or may not function if a

malfunction has occurred and the yellow !

ABS warning lamp lights up continuously aer

the vehicle is started.

Function of o-road ABS

O-road ABS is activated automatically when

you select the F drive program.

O-road ABS is specially adapted for driving o-

road:

The front wheels lock cyclically during braking.

The braking distance is shortened due to the

digging-in eect.

System limits

O-road ABS functions at speeds below

40 km/h.

If O-road ABS intervenes, the ability to steer

may be restricted.

Function of BAS

WARNING Risk of an accident caused by a

malfunction in BAS (Brake Assist System)

If BAS is malfunctioning, the braking distance

in an emergency braking situation is

increased.

Depress the brake pedal with full force in

emergency braking situations. ABS pre-

vents the wheels from locking.

The Brake Assist System (BAS) supports your

emergency braking situation with additional brake

ted and attentive driver. On long journeys, take

regular breaks in good time that allow for ade-

quate recovery.

You can choose between two settings:

Standard: normal system sensitivity.

Sensitive: higher system sensitivity. The driver

was warned earlier, and the attention level

detected by ATTENTION ASSIST has adapted

accordingly.

If drowsiness or increasing lapses in concentra-

tion are detected, the

ATTENTION ASSIST: Take

a break!

warning appears on the driver's display.

You can acknowledge the message and take a

break where necessary. If you do not take a break

and ATTENTION ASSIST continues to detect

increasing lapses in concentration, you will be

warned again aer a minimum of 15 minutes.

The following information is displayed in the driv-

er's display:

The length of the journey since the last break

the attention level determined by ATTENTION

Cruise control and limiter

▌Function of cruise control

Cruise control regulates the speed to the value

selected by the driver.

Forexample, the stored speed is not deleted if you

accelerate to overtake. If you remove your foot

from the accelerator pedal aer overtaking, cruise

control will resume speed regulation back to the

stored speed.

You can store any speed above 20 km/h up to the

maximum design speed or up to the set winter

tyre limit.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

dangers (/ page 321).

Mercedes‑AMG vehicles: cruise control is availa-

ble up to a maximum speed of 250 km/h.

Displays in the driver's display

Grey: cruise control is selected but not yet

active or temporarily passive.

Green: cruise control is active.

A stored speed appears under the h display

and is indicated in the speedometer.

System limits

Cruise control may be unable to maintain the

stored speed on uphill gradients. The stored

speed is resumed when the gradient evens out.

Change into a lower gear in good time on long and

steep downhill gradients. Take particular note of

this when driving a laden vehicle. Doing so will

make use of the engine's braking eect. This

relieves the load on the brake system and pre-

vents the brakes from overheating and wearing

too quickly.

Do not use cruise control in the following situa-

tions:

In trac situations which require frequent

changes of speed, e.g. in heavy trac, on

winding roads

, and slippery roads. Accelerating can cause

the drive wheels to lose traction, and the vehi-

cle could skid.

F247 0074 02

▌Function of the limiter

The limiter restricts the speed of the vehicle. To

reduce the speed to the set speed, the limiter

applies the brakes automatically.

You can limit the speed as follows:

Variable: for short-term limitation of the driv-

ing speed, e.g. in built-up areas

Permanent: for a longer-term speed restric-

tion, e.g. in winter tyre mode

You can store any speed above 20 km/h up to the

maximum design speed or up to the set winter

tyre limit. You can also perform settings while the

vehicle is stationary if the vehicle has been star-

ted.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

dangers (/ page 321).

Mercedes‑AMG vehicles: The limiter is only availa-

ble up to a maximum speed of 250 km/h.

Displays in the driver's display

▌Function of Active Speed Limit Assist

If a changed speed limit is detected and the auto-

matic adoption of speed limits is switched on, this

is automatically adopted as the stored speed

(/ page 345). Speed limits below 20 km/h are

not accepted.

Adjustment of travel speed is initiated no later

than when the vehicle is level with the trac sign.

For signs indicating entry into an urban zone, the

speed is adapted according to that permitted

within the built-up area. The speed restriction indi-

cator on the driver display is always refreshed

when the vehicle is level with the trac sign.

If you are driving on German motorways with no

speed limit, the system uses the speed stored for

a stretch of road with no speed limit as the set

speed. If you do not alter the stored speed on a

stretch of road with no speed limit, the recom-

mended speed of 130 km/h is adopted.

Driving and parking

343

F247 0074 02

If Active Distance Assist DISTRONIC has been put

into passive mode by pressing the accelerator

pedal, only speed limits which are higher than the

set speed are adopted.

The maximum permissible speed does not con-

sider the road condition and current weather and

trac conditions. Adjust your speed accordingly

when necessary.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

potential dangers (/ page 321).

System limits

The system limits of Trac Sign Assist apply to

the detection of trac signs (/ page 359).

Speed limits below 20 km/h are not automatically

adopted by the system as the stored speed. Tem-

porary speed restrictions ( a specic time

or due to weather conditions) cannot be unequiv-

ocally detected by the system.

Adjust the speed in these situations.

▌Function of route-based speed adaptation

When Active Distance Assist DISTRONIC is activa-

ted, the vehicle speed will be adapted to the route

events ahead. Depending on the drive program

selected, the vehicle negotiates a route event

ahead in an energy-saving, comfortable or

dynamic manner. When the route event has been

passed, the vehicle accelerates again to the

stored speed. The set distance to the vehicle in

front, vehicles detected ahead and speed restric-

tions ahead are taken into account.

Route-based speed adaptation can be activated in

the multimedia system (/ page 345).

The following route events are taken into account:

Bends

Roundabouts

T-junctions

Turns and exits

Also, the speed is reduced if the turn signal indi-

cator is switched on and one of the following sit-

uations is detected:

Turning o at junctions

Driving on slowing-down lanes

Driving on lanes adjacent to slowing-down

lanes

The driver is responsible for choosing the right

speed and observing other road users. This

applies in particular to junctions, roundabouts and

344

Driving and parking

F247 0074 02

trac lights, as route-based speed adaptation

does not brake the vehicle to a standstill.

When route guidance is active, the rst speed

adjustment is carried out automatically. If the turn

signal indicator is switched on, the selected route

is conrmed and further speed adaptation is acti-

vated.

Speed adaptation is cancelled in the following

cases:

If the turn signal indicator is switched o

before the route event and it is presumed that

the route event is not deemed relevant by the

driver

If the driver depresses the accelerator or

brake pedal during the process.

System limits

Route-based speed adaptation does not take right

of way regulations into account. The driver is

responsible for complying with road trac regula-

tions and driving at a suitable speed.

In dicult conditions, the speed selection made

by the system may not always be suitable. This

applies to the following situations, for example:

The road's course is not clearly visible

Road narrowing

Varying maximum permissible speeds in indi-

vidual lanes, for example, at toll stations

Wet road surfaces, snow or ice

If transport equipment, for example a trailer or

bicycle rack, is attached to the trailer hitch

and the electrical connection has been cor-

rectly established

In these situations the driver must intervene

accordingly.

WARNING Risk of accident in spite of

route-based speed adaptation

Route-based speed adaptation can malfunc-

tion or be temporarily unavailable in the fol-

lowing situations:

If the driver does not follow the calculated

route

If map data is not up-to-date or available

In the event of roadworks

In bad weather or road conditions

If the accelerator pedal is depressed

In the event of electronically displayed

speed limitations

Adapt the speed to the trac situation.

DSR (Downhill Speed Regulation)

▌Function of the DSR system

DSR is an aid to assist you when driving downhill.

It keeps the speed of travel at the selected target

speed. The steeper the downhill gradient, the

greater the DSR braking eect on the vehicle. On

at stretches of road and uphill gradients, the

DSR brakes the vehicle minimally or not at all.

When DSR is activated and the transmission is in

position h, k or i, DSR controls the driving

speed. The target speed can be set to a value

between 2 km/h and 18 km/h. By braking or

accelerating, you can drive at a higher or lower

speed than the target speed at any time.

DSR will be switched o automatically

If you are driving at a speed greater than

45 km/h

If you change the drive program

The î

off message appears in the driver's dis-

play. The status indicator in the driver's display

goes out. You also hear a warning tone.

DSR remains activated in drive program

▌Information on DSR

WARNING Risk of skidding and accident

when DSR is activated on slippery road

surfaces

If the driven speed and the target speed dier,

the wheels may lose traction.

Take into account the road surface and

the dierence between the driving speed

and target speed before activating DSR.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

dangers (/ page 321).

You are always responsible for keeping control of

the vehicle and for assessing whether the downhill

gradient can be negotiated. Depending on road

surface and tyres, DSR may not always be able to

keep to the target speed. Select a target speed

suitable for the environmental conditions and also

apply the brakes yourself if required.

Active Steering Assist

▌Function of Active Steering Assist

Active Steering Assist is only available up to a

speed of 160 km/h. The system helps you to stay

in the centre of the lane by means of moderate

steering interventions. Depending on the speed

driven, Active Steering Assist uses the vehicles

ahead and lane markings as a reference.

Driving and parking

347

F247 0074 02

Depending on the country, in the lower speed

range Active Steering Assist can use the sur-

rounding trac as a reference. Active Steer-

ing Assist can also assist when driving outside

the centre of the lane, forexample, to form an

emergency corridor.

If the detection of lane markings and vehicles

ahead is impaired, Active Steering Assist switches

to passive mode. The system provides no support

in this case.

Status display of Active Steering Assist

mode, the Ø symbol is shown as grey in

the driver display.

Depending on the selected vehicle settings,

Active Steering Assist may be unavailable.

Steering and touch detection

The driver is required to keep their hands on the

steering wheel at all times and be able to inter-

vene at any time to correct the course of the vehi-

cle and keep it in lane. The driver must expect a

change from active to passive mode or vice versa

at any time.

If the system detects that the driver has not

steered the vehicle for a considerable period of

time or has removed their hands from the steering

wheel, display 1 appears. If the driver still does

not steer the vehicle, a warning tone sounds in

addition to the visual warning message.

If the driver does not react to this warning for a

considerable period, an emergency stop is initi-

ated (/ page 350).

The warning is not issued or stops as soon as the

system detects the driver touching or steering the

steering wheel.

The touch detection may be limited or inoperative

if there is no direct contact between the hand and

the steering wheel, e.g. when wearing gloves or if

there is a steering wheel cover on the steering

wheel.

If Active Steering Assist detects that a system

limit has been reached, a visual warning is issued

and a warning tone sounds.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

potential dangers (/ page 321).

System limits

Active Steering Assist has a limited steering tor-

que for lateral guidance. In some cases, the steer-

ing intervention is not sucient to keep the vehi-

cle in the lane or to drive through exits.

348

Driving and parking

F247 0074 02

The system may be impaired or inoperative in the

following instances:

There is poor visibility, e.g. due to snow, rain,

fog, heavy spray, greatly varying light condi-

tions or strong shadows on the carriageway.

There is glare, e.g. from oncoming trac,

direct sunlight or reections.

Insucient road illumination.

The windscreen is dirty, misted up, damaged

or covered in the vicinity of the camera, e.g.

by a sticker.

There are no lane markings in a given lane, or

the markings are not easily discernible or

change quickly, forexample, in a construction

area or junctions.

The lane markings are worn away, dark or cov-

ered up, e.g. by dirt or snow.

If the distance to the vehicle in front is too

short and the lane markings cannot therefore

be detected.

The roadway is narrow and winding.

There are obstacles on the lane or projecting

out into the lane, suchas object markers.

If transport equipment, forexample a trailer or

bicycle rack, is attached to the trailer hitch

and the electrical connection has been cor-

rectly established.

The system does not provide assistance in the fol-

lowing conditions:

On tight bends and when turning.

When crossing junctions.

At roundabouts or toll stations.

When the tyre pressure is too low.

WARNING Risk of accident if Active Steer-

ing Assist unexpectedly stops functioning

If the system limits of Active Steering Assist

are reached there is no guarantee that the

system will remain active or will keep the vehi-

cle in lane.

Always keep your hands on the steering

wheel and observe the trac carefully.

Always steer the vehicle paying attention

to trac conditions.

WARNING Risk of accident if Active Steer-

ing Assist unexpectedly intervenes

Function of Active Emergency Stop Assist

The following function is only available in com-

bination with the Driving Assistance Package.

Active Emergency Stop Assist monitors the steer-

ing wheel, accelerator, and brake pedals. If the

system detects a lack of driver activity and the

vehicle is in danger of leaving the lane, a warning

can be issued and an emergency stop initiated.

If Active Steering Assist is switched o, the sys-

tem is available from a speed of approx. 60 km/h.

If the system detects that the vehicle is in danger

of leaving the lane, a warning can be issued and

an emergency stop initiated.

The driver has not touched the steering wheel

for a certain while, or no steering movement is

detected for a lengthy period (depending on

the vehicle equipment).

Neither the accelerator nor the brake pedal is

depressed.

If Active Steering Assist is switched on and

active, the system only monitors the steering

wheel. If the driver has not touched the steer-

ing wheel for a certain while, a warning may

be issued despite pedal actuation.

Observe also the instructions on the touch

detection of Active Steering Assist

(/ page 347).

Active Emergency Stop Assist issues the following

further reduce the distance, the vehicle in front is

also highlighted in red. When the system detects a

risk of collision, red radar waves

2 appear ahead

of the vehicle.

Vehicles with PRE-SAFE

: depending on the

country, an additional haptic warning occurs

in the form of slight, repeated tensioning of

the seat belt.

If you do not react to the warning, autonomous

braking can be initiated in critical situations.

In particularly critical situations, Active Brake

Assist can also initiate autonomous braking

directly. In this case, the warning tone and dis-

tance warning lamp L are simultaneous with

the braking action.

If you apply the brakes yourself in a critical situa-

tion or apply the brakes during autonomous brak-

ing, situation-related braking assistance is given.

The brake pressure increases up to emergency

braking level if necessary.

If autonomous braking, situation-related braking

assistance or evasive action has occurred, pop-up

1 appears in the driver's display. It automatically

disappears aer a short time.

If the autonomous braking function or the situa-

tion-related braking assistance is triggered, addi-

tional preventive measures by PRE-SAFE

occu-

pant protection may also be initiated.

WARNING Risk of an accident caused by

limited detection performance of Active

Brake Assist

Active Brake Assist cannot always clearly iden-

tify objects and complex trac situations.

In such cases, Active Brake Assist might:

Give a warning or brake without reason

Not give a warning or not brake

Active Brake Assist is only an aid. The driver is

responsible for maintaining a suciently safe

distance to the vehicle in front, vehicle speed

and for braking in good time.

Always pay careful attention to the trac

situation; do not rely on Active Brake

Assist alone.

Be prepared to brake or swerve if neces-

sary.

If Active Brake Assist is deactivated or the func-

tions are restricted, e.g. owing to activation of

another driving system, the Active Brake Assist

ê warning lamp appears in the driver's dis-

play.

If the system is unavailable owing to soiled or

damaged sensors or a fault, or if the functions are

restricted, the Active Brake Assist Ó warning

lamp appears in the driver's display.

352

ing function warns you if for several seconds, the

distance to the vehicle ahead is insucient at the

current speed. In this case, the distance warning

lamp L in the driver's display lights up. If the

distance to the vehicle ahead continues to

decrease at higher speeds, the distance warning

lamp L begins to ash.

Collision warning

The collision warning can assist you in the follow-

ing situations with an intermittent warning tone

Active Evasive Steering Assist

WARNING Risk of accident despite Active

Evasive Steering Assist

Active Evasive Steering Assist cannot always

clearly identify objects and complex trac sit-

uations.

In such cases, Active Evasive Steering Assist

might:

issue an unfounded warning or initiate a

steering intervention

not issue a warning or not initiate a steer-

ing intervention.

The Active Evasive Steering Assist can provide

support in preventing a collision via an auto-

matically initiated steering intervention.

Always pay careful attention to the trac

situation; do not rely on Active Evasive

Steering Assist alone.

Be prepared to brake or swerve if neces-

sary.

Drive with adjusted speed if pedestrians

are in the area surrounding the road.

Active Evasive Steering Assist can automatically

react to objects that are stationary or moving lon-

gitudinally in your lane.

Active Evasive Steering Assist has the following

characteristics:

detection of pedestrians, cyclists and vehicles.

assistance by autonomous steering interven-

tion during a necessary evasive manoeuvre

autonomous activation if there is sucient

space in your own lane

Reaction from a speed of approximately

30 km/h up to a speed of approximately

80 km/h.

When Active Evasive Steering Assist is interven-

ing, and for the duration of the evasive action, a

warning tone is sounded and the distance warning

lamp L ashes.

The steering assistance by Active Evasive Steering

Assist can be cancelled at any time by steering,

accelerating or braking.

Active Evasive Steering Assist can intervene in the

following speed ranges:

when approaching stationary vehicles, pedes-

trians or cyclists at speeds from approximately

Speed Limit Assist detects speed limits with the

multifunction camera and displays them in the

driver display and optionally in the head-up dis-

play. The camera also detects speed limits with a

restriction indicated by an additional sign (e.g. in

wet conditions).

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognise

potential dangers (/ page 321).

Notes on trailer operation

Observe also the notes on trailer operation

(/ page 394).

If a trailer or bicycle rack is connected correctly,

the central display shows the query about the

type of trailer and its maximum permissible speed

(/ page 399).

The driver must manually adjust the maximum

permissible speed in the

small or large trailer cat-

egory.

In particular, the country-specic laws must be

taken into account, e.g. on:

maximum design speed or maximum permissi-

System limits

The system may be impaired or inoperative in the

following situations in particular:

If visibility is poor, e.g. due to insucient illu-

mination of the road, highly variable shade

conditions, rain, snow, fog, swirling dust or

heavy spray.

If there is glare, e.g. from oncoming trac,

direct sunlight or reections.

If there is dirt on the windscreen in the vicinity

of the multifunction camera or if the camera is

misted up, damaged or obscured.

If the trac signs are dicult to see because,

forexample, they are dirty, obscured, faded,

iced over, damaged, inconveniently positioned,

insuciently illuminated or askew.

Active trac signs with LED displays may not

be detected correctly, or even at all due to

technical factors, suchas transmission fre-

quency.

If the signs, road markings or road layout are

ambiguous, e.g. in the case of trac signs at

road works, at exits and on-ramps, in the case

of adjacent lanes or parallel roads, in the case

of pedestrian crossing markings at trac

lights.

If the signage or road markings do not comply

with the standard.

Trac Sign Assist

▌Function of Trac Sign Assist

This function is an on-demand feature

(/ page 77).

Trac Sign Assist detects the trac signs with

the multifunction camera and compares them

with the information on the digital road map of the

navigation system. It supports you by showing

detected speed limits and overtaking bans on the

driver display. Maximum permissible speeds can

also be shown on the head-up display.

The system can issue a warning when you exceed

the maximum permissible speed.

In some countries, the system can provide you

with further functions and can warn you when you

are approaching pedestrian crossings. If the sys-

tem detects that you are driving onto a section of

Driving and parking

359

road in the wrong direction of travel, it triggers a

warning.

The camera also detects and analyses trac

signs with a restriction indicated by an additional

sign (e.g. in wet conditions).

Trac Sign Assist portrays only selected signs on

the driver display. Actual trac signs and speed

limits have priority over trac signs and speed

limits shown on the driver display.

Notes on trailer operation

Observe also the notes on trailer operation

(/ page 394).

If a trailer or bicycle rack is connected correctly,

The system can intervene if the following condi-

tions are met:

Active Lane Keeping Assist detects a lane

marking.

One of your front wheels moves onto this lane

marking.

If you activate the direction indicators, there is no

steering intervention on that side.

There is no steering intervention if you leave your

lane without activating the direction indicators but

there is a risk of collision with a moving obstacle

in your own lane.

Vehicles with Blind Spot Assist or Driving Assis-

tance Package: If the system detects an obstacle,

e.g. another vehicle, in the adjacent lane, there is

steering intervention despite the direction indica-

tors.

In the following cases a warning 1 appears in

the driver's display and a warning tone is soun-

ded:

a steering intervention by Active Lane Keeping

Assist has a duration longer than approx-

imately ten seconds.

there are two or more steering interventions

by the systems within approximately three

minutes, without steering action by the driver.

Parking Assist PARKTRONIC

▌Function of Parking Assist PARKTRONIC

Parking Assist PARKTRONIC is an electronic park-

ing assistance system that monitors the area sur-

rounding your vehicle and visually and audibly

shows you the distance between the vehicle and a

detected obstacle.

The passive side impact protection also warns you

of obstacles to the side. These must be detected

beforehand by the sensors in the front or rear

bumper while driving past them. If you steer in the

direction of a detected obstacle and there is a risk

of a lateral collision, a warning is issued.

Passive side impact protection can be activated

and deactivated via the multimedia system

(/ page 383).

For front or rear obstacles to the side to be dis-

played, the vehicle must rst travel a distance of

at least half a vehicle length. Once the vehicle has

travelled a distance of one vehicle length, obsta-

cles on all sides can be shown.

Parking Assist PARKTRONIC is only an aid. It is

not a substitute for you paying attention to the

surroundings. The responsibility for safe manoeu-

vring and parking remains with you. Make sure

that there are no persons, animals or objects in

the manoeuvring area while manoeuvring and

parking in/exiting parking spaces.

assistance of the reversing camera and 360°

camera. When you are driving forwards up to

approximately 35 km/h, the system automatically

measures parking spaces on both sides of the

vehicle.

Active Parking Assist serves solely as an aid. It is

not a substitute for you having to pay attention to

Driving and parking

383

F247 0074 02

your surroundings. The responsibility for safe

manoeuvring and parking remains with you.

Ensure that no persons, animals or objects etc.

are in the manoeuvring range.

Active Parking Assist oers the following func-

tions:

Vehicles with reversing camera

Parking in parking spaces parallel to the road-

way

Reversing into parking spaces perpendicular

to the roadway

The parking space is freely selectable. The park-

ing procedure is executed with the vehicle revers-

ing.

Vehicles with 360° camera

Parking in parking spaces parallel to the road-

way

Parking in parking spaces perpendicular to the

roadway (either forwards or reversing as

desired)

Parking in parking spaces that can only be

detected as such from markings (forexample

at the roadside)

Exiting parking spaces if you have parked

using Active Parking Assist

The parking space is freely selectable. The park-

ing direction (forwards or reversing) can also be

freely selected, depending on the orientation of

the parking space.

If Active Parking Assist is available, the Ç mes-

sage appears in the driver display. When the sys-

tem detects parking spaces, È appears. The

arrows show the side of the roadway on which

free parking spaces are located. These are then

shown on the central display.

When Active Parking Assist is activated, the turn

signal indicators are activated based on the calcu-

lated path of your vehicle. The procedure is assis-

ted by acceleration, braking, steering, and gear

changes when entering or exiting a parking space.

To start the parking procedure, press the button

c (/ page 385).

Active Parking Assist will be cancelled in the fol-

lowing situations:

You press the c button again.

Parking Assist is not available.

Objects above or below the detection range of

Active Parking Assist, e.g. protruding loads, over-

hangs or loading ramps of trucks or parking space

boundaries are not detected when measuring the

parking space. Neither are these subsequently

taken into account when calculating the parking

procedure. In some circumstances, Active Parking

Assist may prematurely guide you into the parking

space or brake too late.

Certain environmental conditions, suchas snowfall

or heavy rain, may lead to a parking space being

384

WARNING Risk of accident due to unsuita-

ble trailers

Trailers with a steered axle or a h wheel

cannot be used with Trailer Manoeuvring

Assist.

Due to this, the trailer cannot be manoeuvred

in the desired direction and you can cause a

collision or the trailer can overturn.

Only use Trailer Manoeuvring Assist with

trailers with xed drawbars and axles.

NOTE Damage due to overhanging loads

in front or drawbar installations

The vehicle and the trailer may be damaged

during manoeuvring due to overhanging loads

at the front of the trailer or drawbar installa-

tions.

Pay attention to overhanging loads or

drawbar installations while manoeuvring.

Trailer Manoeuvering Assist assists you when

reversing with a trailer. The reversing camera

monitors the articulation angle between the vehi-

392

Driving and parking

F247 0074 02

cle and the trailer and adjusts it to a specied

value. Trailer Manoeuvering Assist also limits your

speed.

Trailer Manoeuvering Assist is only an aid. It is not

a substitute for your attention to your surround-

ings. The responsibility for safe manoeuvring and

parking remains with you. Ensure that there are

no persons, animals or objects in the manoeu-

vring area while manoeuvring and parking in/exit-

ing parking spaces.

You can enter the articulation angle value directly

via the multimedia system or use a straightening

or 90° manoeuvre. When carrying out a straight-

ening manoeuvre, the system calculates the artic-

ulation angle automatically and straightens the

vehicle/trailer combination to the trailer's current

direction.

Observe the notes on towing a trailer

(/ page 394).

The picture is illustrative and shown without a

trailer.

You can select various manoeuvres in the Trailer

Manoeuvering Assist menu. The manoeuvres

available depend on the trailer's current articula-

tion angle and length.

To adjust the articulation angle: select 4. To

change the articulation angle, swipe to the le

or right in the central display in the entire area

of the camera image.

To activate the straightening manoeuvre:

select 2.

The system calculates the articulation angle in

such a way that the direction of the trailer at

the time of activation is maintained. There is a

short countersteering movement of the trailer

while the vehicle is reversed, guiding it back to

the desired line. In this way, the vehicle is

aligned straight with the trailer, and, at the

same time, the trailer's direction is main-

tained.

To activate the 90° manoeuvre:

Align the vehicle in the same direction

(line) as the trailer.

Select (le or right)

The system calculates the articulation angle

so that a trailer can be manoeuvred into a

driveway at the smallest possible angle when

it is perpendicular to its own vehicle. Aer

turning, the vehicle is aligned again in the trail-

er's direction.

Accelerate and brake as required.

The maximum articulation angle depends on

the length of the trailer. The system calculates

this by driving the vehicle forwards, including

cornering. Before the trailer length has been

calculated, the maximum articulation angle is

approximately 23°. The longer the trailer is,

the higher the maximum articulation angle

(max. approximately 60°).

Be aware of all surroundings and always

remain ready to brake.

WARNING Risk of accident due to car/

trailer combination swerving

If you drive too fast in trailer operation, the

car/trailer combination may start to swerve.

This could cause you to lose control of the

car/trailer combination. The car/trailer com-

bination may even overturn.

Under no circumstances should you try

to straighten the car/trailer combination

by increasing your speed.

Reduce the speed and do not counter-

steer.

Brake if necessary.

NOTE Damage to the engine due to over-

heating

bicycle rack.

Only use bicycle racks approved by

Mercedes-Benz properly as described

below.

NOTE Increased risk of damage to prop-

erty due to folded-out ball neck

When the trailer is not coupled or the

bicycle rack is attached, fold in the ball

neck or, in the case of a fully electric

trailer hitch, retract the ball neck.

NOTE The operating permit may be invali-

dated due to the illegal installation of

trailer hitches

The installation – including retrotting – of a

non-folding or non-removable trailer hitch that

even partially conceals the license plate or the

lighting system is prohibited.

Observe the applicable legal regulations

for the installation of trailer hitches.

Depending on the bicycle rack's design, up to

three bicycles can be transported on the bicycle

rack.

When mounted by attaching to ball head

1, the

maximum load capacity is 75 kg.

The maximum load capacity is calculated from the

weight of the bicycle rack and the bicycle rack

load.

Observe the notes on driving with a roof load,

trailer or fully laden vehicle (/ page 253).

When using a bicycle rack, set the tyre pressure

for increased load on the rear axle of the vehicle.

Further information on the tyre pressure can be

found in the tyre pressure table (/ page 622).

Notes on loading

The larger the distance between the load's centre

of gravity and the ball head, the greater the load

on the trailer hitch.

Therefore, observe the following notes:

mount heavy bicycles as close to the vehicle

as possible

always distribute the load on the bicycle rack

as evenly as possible across the vehicle's lon-

gitudinal axis

Mercedes-Benz recommends removing all detach-

able parts from bicycles (e.g. baskets, child seats,

rechargeable batteries) before loading them onto

the bicycle rack. This will improve the aerody-

namic resistance and centre of gravity of the bicy-

cle rack.

Always secure the bicycles to prevent them from

moving around and check them at regular inter-

vals to ensure that they are secure.

Do not use tarpaulins or other covers. The driving

characteristics and rear view may be impaired. In

addition, aerodynamic resistance and the load on

the trailer hitch will increase.

Vehicle towing instructions

The vehicle is not suitable for the use of tow bar

systems that are used for at towing or dinghy

towing, for example. Attaching and using tow bar

systems may result in damage to the vehicle.

When you are towing a vehicle with tow bar sys-

tems, safe driving characteristics cannot be guar-

anteed for the towing vehicle or the towed vehicle.

The vehicle-trailer combination may swerve from

side to side.

Observe the following information:
