Adaptive Highbeam Assist Plus
Gene ral notes
Wit hAdaptive Highbea mAssis tPlus, you can
automatically switch between low-beam ,partial
high-beam and high-beam headlamps.
Partial high-beam is afor mof illumination
whereby th ehigh-beam is directe dpast other
road users. Other road user sare kept out of th e
high-beam. This prevents glare. When there is a
vehicl ein front, for example, th ehigh-beam
headlamp silluminate th eareas to it sright and
left, and th evehicl ein fron tis illuminate dby th e
low-beam headlamps.
The system automatically adapt sth elow-beam
headlamp range depending on th edistanc eto
th eother vehicle. Once th esystem no longer
detects any other vehicles, it reactivates th e
high-beam headlamps.
If th ehigh-beam or partial high-beam are caus -
ing to omuc hreflection from traffic signs, th e
lights are automatically dimmed and glar efor
th edriver caused by th ereflection sis thus avoi -
ded.
The system' soptical sensor is locate dbehind
th ewindshield near th eoverhead control panel.

Interior lighting control
General notes
In order to prevent the vehicle's battery from
discharging, the interior lighting functions are
automatically deactivated after some time
except when the SmartKey is in position 2in the
ignition lock.
The color, brightness, zone and display lighting
for the ambient lighting are set using the multi-
media system (see the separate operating
instructions).
The interior lighting control can be operated
using the front overhead control panel.
Automatic interior lighting control
XTo switch on or off: press the|button.
When the automatic interior lighting control is
activated, the button is flush with the over-
head control panel.
The interior lighting automatically switches on if
you:
Runlock the vehicle
Ropen a door
Rremove the SmartKey from the ignition lock
The interior light is activated for a short while
when the SmartKey is removed from the ignition
lock. This delayed switch-off can be adjusted via the multimedia system (see the separate oper-
ating instructions).

Replacing bulbs
The front and rear light clusters of your vehicle
are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out the
work required.
Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly.
Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Vehicles with a rain sensor: if the windshield
becomes dirty in dry weather conditions, the
windshield wipers may be activated inadver-
tently. This could then damage the windshield wiper blades or scratch the windshield.

GWARNING
If children open the vial, they could drink the
perfume or it could come into contact with
their eyes. There is a risk of injury. Do not
leave children unsupervised in the vehicle.
If the perfume liquid has been drunk, consult
a doctor. If perfume comes into contact with
your eyes or skin, rinse the eyes with clean
water. If you continue to experience difficul-
ties, consult a doctor.
HEnvironmental note
Full vials must not be dis-
posed of with household

GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
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.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.

The SmartKey can be turned in the ignition lock
even if it is not the correct SmartKey for the
vehicle. The ignition is not switched on. The
engine cannot be started.
Start/Stop button
General notes
All vehicles are equipped with a removable
Start/Stop button.
The Start/Stop button must be inserted in the
ignition lock and the Smartkey must be in the
vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
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 Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
162Driving
Driving and parking
To start the vehicle without actively using the
Smartkey:
Rthe Start/Stop button must be inserted in the
ignition lock.
Rthe Smartkey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 80).
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart-
Key.
Do not keep the SmartKey in the temperature-
controlled cup holder (
Ypage 332). Otherwise,
the key will not be detected, e.g. when starting
the engine with the Start/Stop button.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou 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 front door (
Ypage 86), you can continue
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.
