2022 MERCEDES-BENZ CLS COUPE Owners Manual

&
WARNING Risk of skidding and of an acci-
dent due t o shising down on slippery road
surfaces
If you shis do
wn on slippery road surfaces to
increase the engine braking eMect, the drive
wheels may lose traction. 
Do not shis do
wn on slippery road surfa-
ces to increase the engine braking
eMect. &
DANGER Risk of f
atal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient v
entila-
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
t

he vehicle free from snow when the
engine or the stationary heater is run-
ning. 
Open a window on the side of the vehicle
f

acing away from the wind to ensure an
adequate supply of fresh air. &
WARNING Risk of accident due t
o the
brake system overheating
If you leave your foot on the brake pedal when
dr
iving, 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
acceler
ator pedal at the same time while
driving. *
NOTE Engine damag
e due to excessively
high engine speeds The engine will be damaged if you drive with
t

he engine in the overrevving range. 
Do not drive with the engine in the over-
r
evving range. *
NOTE Causing w
ear to the brake linings by
permanently depressing the brake pedal 
Do not permanently depress the brake
pedal while dr

iving. 
To use braking eMect of t
he engine, shis
to a lower gear in good time. *
NOTE Damag
e to the drivetrain and
engine when pulling away 
Do not warm up the engine while the
v

ehicle is stationary. Pull away immedi-
ately. 
Avoid high engine speeds and driving at
full t

hrottle until the engine has reached
its operating temperature. *
NOTE Damag
e to the catalytic converter
due to non-combusted fuel The engine is not running smoothly and is mis-
Nr

ing.
Non-combusted fuel may get into the catalytic
converter. 158
Driving and parking


Only depress the accelerator pedal
slightl
y. 
Have the cause r
ectiNed immediately at
a qualiNed specialist workshop. *
NOTE R
educed battery life due to frequent
short-distance trips The 12 V battery may not be
suPcientl
y
charged when the vehicle is used only for
short-distance trips. This reduces the life of
the battery. 
Drive longer distances regularly to
c

harge the battery. *
NOTE Damag
e to the vehicle due to not
observing the maximum permitted head-
room clearance If the vehicle height is greater than the maxi-
mum per
mitted 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
per
mitted headroom clearance, do not
enter. 
Observe the changed vehicle height with
add-on r
oof equipment. %
Please bear in mind that all the speed values
s

tated 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 v
ehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle's driving and steering
characteristics change.
You should bear the following in mind:
= Do not exceed the permissible roof load and
towing capacity. 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
t
he vehicle ( page 112).
= Drive attentively, and avoid abrupt starts, brak-
ing and steering as well as rapid cornering.
Advice on driving on salt-strewn roads
The 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 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
traPc 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. Driving and parking
159

Observe the following notes during heavy precipi-
t
ation 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 tyr

es ( page 340).
Notes on driving through water on the road
W
ater 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 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 10 km/h; water
can otherwise enter the vehicle interior or
engine compartment. =
V
ehicles travelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible depth of the water.
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

qEC
O start/stop function
%
Depending on the engine, the ECO start/stop
function is no
t available in all drive programs.
Observe the status display on the instrument
display concerning this.
The engine will be switched oM aut
omatically 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, t
he 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 manoeuvre, turn the steering wheel
sharply or engage reverse gear.
% If the system detects an intelligent stop inhibi-
t

or, 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 oM in spite of an intelligent stop
inhibitor.
The engine will restart automatically in the follow-
ing cases:
= Y

ou engage transmission position h or k.
= You depress the accelerator pedal.
= The vehicle requires an automatic engine
start.
= You release the brake pedal. 160
Driving and parking

=
V ehicles 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
20 km/h.
ECO start/stop function symbols on the instru-
ment display:
= The è symbol (green) appears when the
vehicle is at a standstill: the engine was
switched oM by the ECO start/stop function.
= The ç symbol (yellow) appears when the
vehicle is at a standstill: not all vehicle condi-
tions for an engine stop have been met.
= Neither the è symbol nor the ç symbol
appears when the vehicle is at a standstill: an
intelligent stop inhibitor, e.g. a stop sign, has
been detected.
= The s symbol appears: the ECO start/stop
function is deactivated or there is a malfunc-
tion. If the engine was switched
oM b y the ECO start/
stop function and you leave the vehicle, a warning
tone will sound and the engine will not be restar-
ted. In addition, the following display message will
appear on the instrument display:
Vehicle is operational Switch off ignition before
exiting
If you do not switch oM the vehicle, it will automat-
ically be switched oM aser three minutes.
qDeactivating or activating the ECO start/stop
function 
Press button 1.
If indicat

or lamp 2 lights up, the ECO start/
stop function is activated.

ECO display function
The ECO display summarises your driving charac-
t
eristics 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,
t
he outer edge will light up and the segment will
Nll up when the following driving style is adopted:
= 1 Steady speed =
2 Gentle deceler
ation 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 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
centre of display 4. The range displayed does
not indicate a Nxed reduction in consumption. ECO Assist function (vehicles with 48 V on-board
electr
ical system) ECO Assist analyses data for the vehicle's expec-
t

ed 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 251). 1

The segments of dis tance 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
accelerator3 message appears in the Instru-
ment Display. The Nrst segments in front of the vehicle will turn green. The remaining segments
will initiall

y 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 a
response 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 h. 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.
Sy
stem 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. Driving and parking

= 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's
digital map is incorrect or out of date.
= If signs are ambiguous, e.g. road signs in road-
works or in adjacent lanes. DYNAMIC SELECT switch
