MERCEDES-BENZ E CLASS COUPE 2023 Owners Manual

*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 105).
= Drive attentively, and avoid abrupt starts, brak-
ing and steering as well as rapid cornering.
Driving and parking149

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 312).
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.
ECO start/stop function

q ECO 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.
150Driving and parking

If the system has detected one of the followingsituations, 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.
=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).

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.152Driving and parking

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 226).
1Event ahead2Distance display for the event ahead3"Foot oM the accelerator" prompt
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.Driving and parking153

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.=
If there is dirt on the windshield in the area of
the multifunction camera or the camera is fog-
ged up, damaged or obscured.
= If road signs are hard to detect, e.g. due to
dirt, snow or insuPcient lighting, or because
they are obscured.
= If the information on the navigation system\bs
digital map is incorrect or out of date.
= If signs are ambiguous, e.g. road signs in road-
works or in adjacent lanes.
