Useful information
i This 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.

ist workshops (Y page 26). Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. Therefore, your
vehicle is equipped with special daytime run- ning lamps. In some countries, operation of
the headlamps varies due to legal require-
ments and self-imposed obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
(Y page 238). Setting the exterior lighting
Setting options Exterior lighting can be set using:

WARNING
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.

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 parking lamps and the low-beam headlamps are switched on or off
automatically depending on the brightness of the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to Ã.
Canada only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law in 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 238).
If the engine is running and you turn the light
switch to TorL, the manual settings
take precedence over the daytime running
lamps. Low-beam headlamps G
WARNING
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.
Parking lamps ! If the battery has been excessively dis-
charged, the parking lamps or standing
lamps are automatically switched off to
enable the next engine start. Always park
your vehicle safely and sufficiently lit
according to legal standards. Avoid the
continuous use of the Tparking lamps
for several hours. If possible, switch on the
X right or the Wleft standing lamp.
X To switch on: turn the light switch to T.
The green Tindicator lamp in the instru-
ment cluster lights up.
Standing lamps
Switching on the standing lamps ensures the corresponding side of the vehicle is illumina-
ted. Exterior lighting

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.
i The 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. It 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.
Cornering light function with traffic circle
function: The cornering light function is activated on
both sides before entering a traffic circle
through an evaluation of the current GPS
position of the vehicle. It remains active until
after the vehicle has left the traffic circle. In
this way, pedestrians crossing the road, for
example, are illuminated by your vehicle in
good time. 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. Exterior lighting

Important safety notes
G
WARNING
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 Switching Adaptive Highbeam Assist
