Useful information
iThis Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops ( Ypage 25).
Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
Setting the exterior lighting
Setting options
Exterior lighting can be set using: R the light switch
R the combination switch ( Ypage 110)
R the on-board computer ( Ypage 205)
Light switch
Operation
1 WLeft-hand standing lamps
2XRight-hand standing lamps
3 TParking lamps, license plate and
instrument cluster lighting
4ÃAutomatic headlamp mode, control-
led by the light sensor
5 LLow-beam/high-beam headlamps
BRRear fog lamp
CNFog lamp (only vehicles with front
fog lamps)
If you hear a warning tone when you leave the
vehicle, the lights may still be switched on. X Turn the light switch to Ã.
The exterior lighting (except the parking/
standing lamps) switches off automatically ifyou:
R remove the SmartKey from the ignition lock
R open the driver's door with the SmartKey in
position 0.
Automatic headlamp mode
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to L .
108Exterior lighting
Lights and windshield wipers

The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle'slighting at all times. Ã is the favored light switch setting. The
light setting is automatically selected accord- ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
R With the engine running: if you have acti-
vated the daytime running lamps function
via the on-board computer, the daytime
running lamps or the low-beam headlamps
and parking lamps are switched on or off
automatically depending on the brightnessof the ambient light.
X To switch on automatic headlamp mode: turn the light switch to Ã.
Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day- time running lamps function is required by lawin Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to T, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to L, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer( Y page 205). If the engine is running and you turn the light
switch to TorL , the manual settings
take precedence over the daytime runninglamps.
Low-beam headlamps
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to L .
Even if the light sensor does not detect that it is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the L position. This is a particularly useful
function in the event of rain and fog. X To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to position 2or start the engine.
X Turn the light switch to L.
The green Lindicator lamp in the instru-
ment cluster lights up.
Front fog lamps
In conditions where visibility is poor due to
fog, snow or rain, the fog lamps improve vis-
ibility as well as making it easier for other road
users to see you. They can be operated
together with the parking lamps or together
with the parking lamps and low-beam head-lamps. X To switch on the front fog lamps: turn
the SmartKey in the ignition lock to position
2 or start the engine.
X Turn the light switch to Lorà .

only the turn signal lamp on the corre-
sponding side of the vehicle will flash.
X To switch off the hazard warning lamps:
press button :. The hazard warning lamps automatically
switch on if:
R an air bag is deployed or
R the vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 6 mph (10 km/ h)again after a full
brake application.
iThe hazard warning lamps still operate if
the ignition is switched off.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. The corner- ing light function can only be activated when
the low-beam headlamps are switched on.
Active: R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.

Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to identify pedes-
trians, cyclists and animals.
Active: when the lights are switched on.
Adaptive Highbeam Assist
General notes
You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to
low beam.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize 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
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late. In this or similar situations, the automatic high-
beam headlamps will not be deactivated or
activated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the high-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 conditions.
In particular, the detection of obstacles can
be restricted if there is: R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured
