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

Checklist aer driving o-road

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.

Clean the following components every time

aer driving o-road:

licence plate

headlamps and tail lights

tyres, wheels and wheel arches

underbody

▌ECO start/stop function

Depending on the engine, the ECO start/stop

function is not available in all drive programs.

Observe the status display on the driver's dis-

play concerning this.

Plug-in hybrid: this function is not available.

The engine will be switched o automatically in

the following situations if all vehicle conditions for

an automatic engine stop are met:

You brake the vehicle to a standstill in trans-

mission position h or i.

Vehicles with a 48 V on-board electrical sys-

tem: you depress the brake pedal when travel-

ling at a low speed.

If the system has detected one of the following

situations, the engine will not stop:

You stop at a stop sign and there is no vehicle

in front of you.

The vehicle that stopped in front of you pulls

away again.

You manoeuvre, turn the steering wheel

sharply or engage reverse gear.

If the system detects an intelligent stop inhibi-

tor, e.g. a stop sign, the engine will not stop.

If you activate the HOLD function or engage

the park position j, the engine can be

switched o in spite of an intelligent stop

inhibitor.

The engine will restart automatically in the follow-

ing cases:

You engage transmission position h or k.

You depress the accelerator pedal.

The vehicle requires an automatic engine

start.

You release the brake pedal.

Vehicles with a 48 V on-board electrical sys-

tem:

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

Driving and parking

F247 0074 02

Standard setting:

hÃ: if the ECO Assist function is activa-

ted in the multimedia system (/ page 267).

h: if the ECO Assist function is deactivated

in the multimedia system.

hÃ is only available if the ECO Assist

function is activated in the multimedia system

and if the function of the radar sensors is not

impaired. Also observe the information on

vehicle sensors and cameras (/ page 321).

To increase recuperation: briey pull gearshi

paddle 1.

To reduce recuperation: briey pull gearshi

paddle 2.

Standard setting: pull and hold gearshi pad-

dle 1 or 2, or engage transmission position

h again.

When the vehicle is started again, the stand-

ard setting is also set.

The driver's display shows the currently selected

recuperation level next to the transmission posi-

tion display.

ECO Assist (plug-in hybrid)

▌ECO Assist function

The following function depends on the equip-

ment and the country and is available only for

plug-in hybrids.

ECO Assist analyses data for the vehicle's expec-

ted route. This allows the system to help optimally

adjust your 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.

The function will be active in the following circum-

stances:

The function is activated in the multimedia

system (/ page 267).
