Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and self-imposed obligations. Driving abroad
It is not necessary to switch your headlamps to symmetrical dipped beam when driving in coun-
tries where vehicles are driven on the opposite
side of the road to the country in which the vehi- cle is registered. Legal requirements are fulfilled
without switching the headlamps to symmetri-
cal dipped beam. Setting the exterior lighting
Setting options Exterior lighting can be set by:
R the light switch

The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps from main beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions. 90

!
Do not warm up the engine when the vehicle
is stationary. Drive off immediately. Avoid
high engine speeds and driving at full throttle
until the engine has reached its operating
temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta- tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! During a cold start with low engine oil tem-
peratures (below 0 †), the maximum engine
speed is restricted in order to protect the
engine. To protect the engine and maintain
smooth engine operation, avoid driving at full throttle when the engine is cold. Key positions
Start/Stop button General notes
All vehicles are equipped with a Start/Stop but-
ton.
The Start/Stop button is located on the centre
console and is illuminated when the vehicle is
unlocked.
The key must be in the vehicle.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehicle. This occurs, for example, when starting the
engine.
If there is a key in the ignition lock, this takes
precedence over the KEYLESS-GO start func-
tion.
To start the vehicle without actively using the
key:
R the key must be in the vehicle
R the vehicle must not be locked with the key or
KEYLESS-GO (Y page 64) Do not keep the key:
R
with electronic devices, e.g. a mobile phone
or another key
R with metallic objects, e.g. coins or metal film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with the
Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the button
on the driver's door (Y page 70), you can con-
tinue to start the engine with the Start/Stop
button.
The engine can be switched off while the vehicle is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.
Key positions with the Start/Stop button When you switch on the ignition, all of the indi-
cator lamps in the instrument cluster light up.
Further information on situations where an indi-
cator lamp either fails to go out after starting the engine or lights up while driving (Y page 196).
If Start/Stop button :has not yet been
pressed, this corresponds to the key being
removed from the ignition. 102

General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (Y page 70).
It is only possible to shift the transmission from position Pto the desired position, if:
R the engine is running and
R you depress the brake pedal
If you do not depress the brake pedal, the E-
SELECT lever can still be moved but the parking lock remains applied.
Information on automatically releasing the elec-
trical parking brake (Y page 122).
Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist. 104

RACE drive program (AMG GT S) The RACE drive program is designed for maxi-
mum performance in terms of shift points and engine speeds. The engine and transmission
should be at normal operating temperature for
the RACE drive program (Y
page 167). Use the
RACE drive program on a closed-off race circuit.
Drive program RACEis characterised by the fol-
lowing:
R the vehicle exhibits driving characteristics
suitable for the racetrack.
R all vehicle systems are set for maximum
sportiness.
R For optimum performance, the transmission
shifts up later and shifts down sooner.
R The multifunction display shows the manual
gearshift program without upshift indicator
(Y page 114).
R the gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (Y page 115). You can follow the
gearshift recommendations at all times and
change gear accordingly using the steering
wheel gearshift paddles. On the basis of the
gearshift recommendation, using the steering wheel gearshift paddles, you can optimise the
drive train and engine operating mode at any
time.
R if you have selected a gear manually, this will
be maintained until the vehicle speed signifi-
cantly increases or decreases.
R If you do not follow the gearshift recommen-
dations, the automatic shift points may result
in high fuel consumption.
R the suspension exhibits particularly rigid
springing and damping settings.
R The transmission shift and response times are
significantly shorter with more aggressive
gear changes. This is particularly the case
when shifting up. The shift strategy is thus
designed to interact dynamically with the
high-revving engine.
R gliding mode is not available.
R the ECO start/stop function is not available. 116
