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.

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement.

You could otherwise fail to recognise

dangers.

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 the vehicle is started:

If the high-voltage battery is suciently

charged, the vehicle can be started with the

electric drive system without the combustion

engine (noiseless start).

If the high-voltage battery for the electric drive

system is not suciently charged or the vehi-

cle conditions 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.

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.

Driving and parking

269

F167 0057 02

Characteristics with high power output requests:

The electric motor supports the combustion

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

or accelerating.

The high-voltage battery is discharging.

Characteristics when the accelerator pedal is

released during the 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.

When you drive in electric mode, the vehicle

may not be heard by other road users owing to

the signicantly reduced operating noise.

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, the combustion engine will be

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 will help 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.

or o.

Then 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. by 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.

Driving and parking

277

F167 0057 02

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 discs 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 for

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 country-specic guidelines for permissible

tolerances (basis: UN-ECE No. 85 or country-

specic guidelines).

Inuencing variables include:

Location above sea level

Fuel quality

Outside temperature

Operating temperature of the engine

The p engine operating temperature warning

lamp will remain lit until the engine has reached

its operating temperature.

Engine output and engine torque will be reduced.

Factor this into your driving style.

When the p engine operating temperature

warning lamp goes out, full engine output and

engine torque will be available.

Notes on optimised acceleration

If all necessary requirements and activation con-

ditions are fullled, the best possible acceleration

can be achieved from a standstill.

Do not use optimised acceleration on public

roads. Individual wheels could spin and you could

lose control of the vehicle. There is an increased

risk of skidding and/or accident.

Be sure to observe the safety notes and informa-

tion on ESP

(/ page 359).

Pulling away with optimised acceleration

WARNING Risk of skidding and accidents

due to wheelspin

If you pull away with optimised acceleration,

individual wheels could spin and you could

lose control of the vehicle.

There is a higher risk of skidding and acci-

dents when ESP

is deactivated in particular.

Make sure that there are no persons or

obstacles in the vicinity of the vehicle.

Requirements

the vehicle is run in (/ page 277).

the vehicle and tyres are in good condition.

the road surface is high-grip.

the engine and transmission are at normal

operating temperature.

278

Driving and parking

F167 0057 02

NOTE Increased wear due to optimised

acceleration

When pulling away with optimised accelera-

tion, all components of the drivetrain are sub-

jected to a very high load.

This can lead to increased component wear.

Do not always pull away with optimised

acceleration.

Engage the h drive position (/ page 310).

Move the steering wheel to the straight-ahead

position.

Select drive program C

(/ page 302).

Deactivating ESP

(/ page 362).

Depress and hold the brake pedal rmly with

your le foot.

Fully depress the accelerator pedal with your

right foot.

Aer no more than ve seconds, quickly take

your le foot o the brake, but keep the accel-

erator pedal depressed.

The vehicle will pull away at maximum acceler-

ation.

Switch on ESP

once the acceleration proce-

dure is complete.

Ending optimised acceleration

Remove your foot from the accelerator pedal.

Reactivate ESP

Aer you pull away with optimised accelera-

tion, components of the drivetrain may

become very hot, which means that optimised

acceleration values may be reached again

only aer a few minutes.

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.

Driving and parking

279

F167 0057 02

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.

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.

280

Driving and parking

F167 0057 02

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.

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.

Observe the notes on driving with a roof load,

trailer or fully laden vehicle.

Driving with a loaded roof luggage rack or trailer,

or with the vehicle fully loaded or occupied,

changes the handling and steering characteristics

of your vehicle.

Therefore please observe the following notes:

Do not exceed the permissible roof load and

trailer load. Also observe the information in

the technical data in this respect.

Distribute the roof load and vehicle load

evenly, and place heavy objects at the bottom.

Also comply with the notes on loading the

vehicle.(/ page 202)

Driving and parking

281

F167 0057 02

Drive carefully, avoiding abrupt starting, brak-

ing and steering as well as fast cornering.

Notes on driving on roads treated with de-icing

salt

The braking eect is limited on road surfaces

treated with de-icing salt.

Please therefore bear in mind the following notes:

Due to salt build-up on the brake discs and

brake linings, the braking distance can

increase considerably or braking may be one-

sided.

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 depress the brake pedal at the end

of the journey and when starting the next jour-

ney

Notes on aquaplaning

Aquaplaning can take place if a certain depth of

water has built up on the road surface.

Observe the following notes during heavy precipi-

tation 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 34).

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 need to drive through

water:

Observe the maximum permissible fording

depth (/ page 850, 847).

Drive at a walking pace at most, otherwise

water may 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 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.

When driving o-road or on unpaved sur-

faces, check the underside of the vehicle

at regular intervals.

In particular, remove any trapped parts

of plants or other ammable material.

If damage should occur, immediately

inform a qualied specialist workshop.

When driving o-road, it is possible that sand,

mud and water, or water mixed with oil, may get

into the brakes. This may lead to a reduction in

braking eect or total brake failure, also as a

result of increased wear. The braking characteris-

tics will vary depending on the material that has

entered the system. Clean the brakes aer driving

o-road. If you then notice reduced braking eect

or hear scraping noises, have the brake system

checked at a qualied specialist workshop. Adapt

your driving style to the modied braking charac-

teristics.

NOTE Damage caused by driving over

obstacles

The vehicle can be damaged by:

driving onto high kerbs or unpaved roads.

quickly driving over obstacles such as

kerbs, speed bumps or potholes.

heavy objects hitting the underbody or

chassis components.

Do not drive over obstacles that could

damage the vehicle.

Check the vehicle regularly for damage

during o-road driving.

Adjust the vehicle speed to suit the road

surface conditions.

If there is damage, consult a qualied

specialist workshop immediately.

ENVIRONMENTAL NOTE Environmental

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 drivetrain can lead to imbalances

and therefore vibrations.

If the F drive program is selected: select

another drive program.

Deactivate DSR.

Lower the vehicle to a level suitable for the

road conditions, e.g. normal level.

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 number

headlamps and tail lamps

tyres, wheels and wheel arches

underbody

Aer driving through sand, mud, water or

gravel, have the following components

checked and cleaned:

brake discs and brake linings

tyres and wheels

axle joints

Information on the AMG ceramic high-perform-

ance composite brake system

The brake system is designed for heavy loads.

This may lead to noise when braking. This eect

can also occur aer washing the vehicle.

The noise depends on the following factors:

speed

brake force

environmental conditions, e.g. temperature

and air humidity

Have the brake system checked at a qualied

specialist workshop aer it has been subjec-

ted to extreme loads.

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

Driving and parking

287

F167 0057 02

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 edge 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 the display

4. The range displayed

does not indicate a xed reduction in consump-

tion.

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 in the direction of travel

on a stylised road 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

288

Driving and parking

F167 0057 02

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 458).

ECO Assist function (vehicles with 48 V on-board

electrical system)

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

tion (/ page 292).

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

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

Driving and parking

289

F167 0057 02

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.

The recuperative braking system converts the

vehicle's kinetic energy into electrical energy dur-

ing overrun and braking.

Depending on the selected recuperation level, the

electric motor is operated as an alternator when

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

while driving in transmission position h, recuper-

ation starts in overrun mode.

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 situation. There is

no deceleration to a standstill. Also brake with the

service brake if necessary. Always adapt your

speed to the driving situation and keep sucient

distance.

290

Driving and parking

F167 0057 02

If you brake heavily, the mechanical brake is

also used. This means that the maximum

recuperation energy cannot be recovered. The

more proactively you accelerate and brake,

the more eciently energy can be recuper-

ated.

System limits

With recuperation in overrun mode, the braking

eect of the electric motor is only reduced or

non-existent in the following situations:

when the high-voltage battery charge level

increases

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

mal operating temperature

▌Manually setting recuperative deceleration

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement.

You could otherwise fail to recognise

dangers.

The 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, anticipatory recuperation

with ECO Assist (/ page 292)

hq No recuperation: the vehicle rolls freely

h Normal recuperation

h± Increased recuperation: Strong vehicle

deceleration in overrun mode, driving

on a downhill gradient

Default setting:

hÃ: If the ECO Assist function in the mul-

timedia system is switched on (/ page 294).

h: If the ECO Assist function in the multime-

dia system is switched o.

hÃ is only available if the ECO Assistant

function in the multimedia system is switched

on and if the function of the radar sensors is

not impaired. Please also note the information

on the vehicle sensors and cameras

(/ page 356).

Increase recuperation: Pull the gearshi pad-

dle 1 briey.

Reduce recuperation: Pull the gearshi paddle

ded for downhill gradients: the steeper the incline,

the higher the recuperation. Depending on the sit-

uation, it may nevertheless be necessary to addi-

tionally depress the brake pedal.

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-
