MERCEDES-BENZ E CLASS WAGON 2023 Owners Manual

Aser no more than Nve seconds, take your les
foot quickly oM the brake, but keep the accel-
erator pedal depressed.
The vehicle will pull away at maximum acceler-
ation.Switch on ESP n
once the acceleration proce-
dure is complete.
Ending optimized acceleration
Remove your foot from the accelerator pedal.Reactivate ESP n
.\bAser you pull away with optimized accelera-
tion, components of the drivetrain can
become very hot, which means that optimized
acceleration values may be reached again only aser a few minutes.
Notes on driving
&WARNING Risk of accident due to objects
in the driver\bs footwell
Objects in the driver\bs footwell may impede
pedal travel or block a depressed pedal.
This jeopardizes the operating and road safety
of the vehicle.Stow all objects in the vehicle securely so that they cannot get into the driver\bs
footwell.Always install the Ooor mats securely
and as prescribed in order to ensure that
there is always suPcient room for the
pedals.Do not use loose Ooor mats and do not
place Ooor 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 oM while driving
If you switch oM the vehicle while driving,
safety functions are restricted or no longer
available.
This may aMect 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 oM the vehicle while driv-
ing.&DANGER Risk of death caused by exhaust
gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and leads to poisoning.
Never leave the engine or, if present, the
auxiliary heating running in an enclosed
space without suPcient ventilation.Driving and parking159

&WARNING Risk of skidding and of an acci-
dent due to shising down on slippery road
surfaces
If you shis down on slippery road surfaces to
increase the engine braking eMect, the drive
wheels may lose traction.
Do not shis down on slippery road surfa-
ces to increase the engine braking
eMect.&DANGER Risk of fatal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient 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 and injury due
to being under the inOuence of alcohol
and drugs while driving
Drinking and driving and/or taking drugs and
driving are very dangerous combinations. Even a small amount of alcohol or drugs can aMect
your reOexes, perceptions and judgment.
The possibility of a serious or even fatal acci-
dent are greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or
allow anyone to drive who has been
drinking or taking drugs.&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 Wearing out the brake linings by
continuously depressing the brake pedalDo not depress the brake pedal continu-
ously whilst driving.To use the braking eMect of the engine,
shis to a lower gear in good time.160Driving and parking

*NOTE Damage to the drivetrain and
engine when pulling awayDo 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-
Nring.
Non-combusted fuel may get into the catalytic
converter.
Only depress the accelerator pedal
slightly.Have the cause rectiNed immediately at
a qualiNed specialist workshop.*NOTE Reduced battery life due to frequent
short-distance trips
The 12 V battery may not be suPciently
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 Damage to the vehicle due to not
observing the maximum permitted head-
room clearance
If the vehicle height is greater than the maxi- mum permitted headroom clearance, the roof
and other parts of the vehicle may be dam-
aged.
Observe the signposted headroom clear- ance.If the vehicle height is greater than the permitted headroom clearance, do not
enter.Observe the changed vehicle height with add-on roof equipment.\bPlease bear in mind that all the speed values
stated in this Operator\bs 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 loaded roof luggage rack or trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle\bs driving and steering
characteristics change.
You should bear the following in mind: = Do not exceed the permissible roof load and
trailer load. Also observe the information in
the Technical Data.
= Distribute the roof load and the load inside the
vehicle evenly, placing heavy objects at the
bottom. Also comply with the notes on loading
the vehicle (  page 110).
= Drive attentively, and avoid abrupt starts, brak-
ing and steering as well as rapid cornering.
Driving and parking161

Advice on driving on salt-strewn roadsThe braking eMect 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 may increase
considerably or result in one-sided braking.
= Maintain a much greater safety distance to the
vehicle in front.
Remove salt build-up as follows: = Brake occasionally, paying attention to the
traPc conditions
= Carefully depress the brake pedal at the end
of the journey and when starting the next jour- ney
Notes on hydroplaning Hydroplaning can take place if a certain depth of
water has built up on the road surface.
Observe the following notes in the event of heavy precipitation or conditions in which hydroplaningmay occur:
= Reduce speed=Avoid tire ruts
= Avoid sudden steering movements
= Brake carefully\bAlso observe the notes on regularly checking
wheels and tires (  page 332).
Notes on fording on the road
Water ingress in the vehicle can damage the engine, electrics and transmission.
Water can also enter through the engine\bs air
intake and cause engine damage.
Observe the following if you have to drive through
water:
= The water, when calm, may only reach the
lower edge of the vehicle body.
= Drive at a maximum speed of 6 mph
(10 km/h); water can otherwise enter the vehicle interior or engine compartment.
= Vehicles traveling in front, or oncoming vehi-
cles, can create waves which may cause the
maximum permissible depth of water to be exceeded.
The braking eMect of the brakes is reduced aser
fording. Brake carefully, paying attention to the
traPc conditions, until braking power has been
fully restored.
Notes on oM-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 Nre caused by Oamma-
ble material on hot exhaust system com-
ponents
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system.
162Driving and parking

When driving on an unpaved road or oM-
road, check the vehicle underside regu-
larly.In particular, remove trapped plant parts
or other Oammable material.If there is damage, consult a qualiNed
specialist workshop immediately.
When driving oM-road, sand, mud and water or
water mixed with oil, etc., may get into the brakes. This may lead to a reduction in braking eMect or
total brake failure as a result of increased wear.
The braking characteristics will vary depending on the material that has entered the system. Clean
the brakes aser driving oM-road. If you then notice
reduced braking eMect or hear scraping noises,
have the brake system checked at a qualiNed spe-
cialist workshop. Adapt your driving style to the changed braking characteristics.
*NOTE Damage caused by driving over
obstacles
The vehicle can be damaged by:
= Driving onto high curbs or unpaved roads.
= Quickly driving over obstacles such as
curbs, 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 oM-road driving.Adjust the vehicle speed to suit the road
surface conditions.If there is damage, consult a qualiNed
specialist workshop immediately.+ENVIRONMENTAL NOTE Environmental
damage due to non-observance of prohibi- tion signs
Environmental protection has priority. Treat
nature with respect.
Be sure to observe prohibition signs.\bThe vehicle is designed for easily negotiable
and moderate oM-road terrain. When driving
oM-road, make sure there is suPcient ground
clearance.

= Select the F driving mode.
= Select a higher vehicle level.
= Shis to a lower gear.
= Drive quickly to overcome the rolling resist-
ance; the vehicle may otherwise dig itself in.
= Drive in the tracks of other vehicles if possi-
ble. Make sure that the following prerequisites
are met:
- the tire ruts are not too deep
- the sand is Nrm enough
- the ground clearance is suPcient
FordingAlso observe the following information when ford-
ing:
= Drive no faster than 6 mph (10 km/h).
= The water, when calm, may only reach the
lower edge of the vehicle body.
= Switch oM automatic climate control
(  page 149).
= Ensure that a bow wave does not form as you
drive.
= Do not stop in the water and do not switch oM
the engine. Ensure the ECO start/stop func- tion is switched oM ( page 166).

Also observe the following information when driv-
ing in mountainous terrain:
= Avoid high engine speeds.
= Use the braking power of the engine when
driving downhill.
= Shis to a lower gear on uphill gradients and on
long, steep downhill gradients.
= Activate DSR before driving downhill, if neces-
sary (  page 204).164Driving and parking

Checklist aser driving oM-road
Driving oM-road places greater demands on your
vehicle than driving on normal roads. Check the entire vehicle for damage and foreign bodies
every time aser driving oM-road. Foreign bodies in
the wheels or drivetrain can lead to imbalances
and therefore vibrations.
= If the F or G driving mode is selected:
select another driving mode.
= Deactivate DSR.
= Lower the vehicle level again to a level suitable
to the road conditions, e.g. to the normal level.
= Apply the brakes to dry them aser fording.
= Check that the service brake is working nor-
mally aser a long downhill stretch.
= Clean the following components every time
aser driving oM-road:
- license plate number
- headlamps and tail lamps
- tires, wheels and wheel arches
- underbody=
Aser driving through sand, mud, water or
gravel, have the following components
checked and cleaned:
- brake disks and brakepads
- tires and wheels
- axle joints
ECO start/stop function

qECO start/stop function
\bDepending on the engine, the ECO start/stop
function is not available in all drive programs.
Observe the status display on the instrument display concerning this.
The engine will be switched oM 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 [ or \\.
= Vehicles with a 48 V on-board electrical sys-
tem: you depress the brake pedal when travel-
ing 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 starts
up again.
= You maneuver, turn the steering wheel sharply
or engage reverse gear.\bIf 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 ], the engine can be
switched oM in spite of an intelligent stop
inhibitor.
The engine will restart automatically in the follow-
ing cases:
= You engage transmission position [ or ^.
= You depress the accelerator pedal.
= The vehicle requires an automatic engine
start.
= You release the brake pedal.
Driving and parking165

=Vehicles with a 48 V on-board electrical sys-
tem:
- You release the brake pedal on a downhill
gradient and the vehicle does not roll.
- The vehicle rolls on a downhill gradient and
does not automatically enter glide mode at 15 mph (20 km/h).
ECO start/stop function symbols on the instru- ment display:
= The

ECO display function
The ECO display summarizes 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.
You can inOuence consumption by doing the fol-
lowing:
= Driving with particular care.
= Following the gearshis recommendations.
The lettering in the segment will light up brightly,
the outer edge will light up and the segment willNll 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 gray, 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 Nll up completely at
the same time
= The edges around all three segments will light
up
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 cen- ter of display 4. The range displayed does not
indicate a Nxed reduction in consumption.ECO Assist function (vehicles with 48 V on-board
electrical system)
ECO Assist analyzes data for the vehicle\bs expec-
ted route. This allows the system to optimally
adjust the driving style for the route ahead, save
fuel and recuperate.
ECO Assist is displayed on the Assistance
menu(  page 245).

Displayable route events 1
The segments of distance display 2 show the
distance to the event ahead as follows:
= A few segments light up: the event ahead is
near.
= Many segments light up: the event ahead is
further away.
When the vehicle nears the event, ECO Assist will
calculate the optimal speed for maximum fuel economy and recuperative energy based on the
distance, speed and gradient. The Foot off the
Accelerator 3 message appears in the Instru-
ment Display. The Nrst segments in front of the
vehicle will turn green. The remaining segments
will initially stay white. If you take your foot oM the
accelerator pedal in good time, the remaining seg-
ments on the display will successively turn green until the event shown is reached. The drivetrain
will be set for maximum fuel economy. Recupera-
tion will charge the battery. Recuperation will be
adapted to the selected drive program.
The event will be shown for a short time aser it
has been passed. If there is no response to the Foot off the Accelerator prompt, the segments
will remain white.
If the event involves a vehicle in front, all seg- ments will immediately turn green once there is aresponse to the Foot off the Accelerator prompt.
For active ECO Assist in drive program ,
symbol 3 will appear on the instrument display
and on the head-up display beside transmission position [. Symbol 3 will also appear when the
assistant display is not selected.
If the system does not intervene during the event
ahead, nothing will be displayed. The system will be passive.ECO Assist is active only in drive programs 
and A .
System limits
ECO Assist can function even more precisely if
the route is adhered to when route guidance is
active. The basic function is also available without
active route guidance. Not all information and
traPc 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 driver must be ready to brake at all
times, irrespective of whether the system inter-venes.
The system may be impaired or may not function
in the following situations:
= If visibility is poor, e.g. due to insuPcient illu-
mination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.168Driving and parking
