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.
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 switched
on 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 the:
Rlight switch
Rcombination switch (Ypage 118)
Ron-board computer (Ypage 230)
Light switch
Operation
1 WLeft-hand standing lamps
2XRight-hand standing lamps
3TParking lamps, license plate and
instrument cluster lighting
4ÃAutomatic headlamp mode, control-
led by the light sensor
5LLow-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.
XTurn the light switch to the Ãposition.
The exterior lighting (except the parking/
standing lamps) switches off automatically if
you:
Rremove the SmartKey from the ignition lock
Ropen the driver's door with the SmartKey in position 0in the ignition lock.
Automatic headlamp mode
à 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):
RKey in position 1in the ignition lock: the
parking lamps are switched on or off auto-

matically depending on the brightness of
the ambient light.
RWith 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.
XTo switch on the automatic headlamp
mode: turn the light switch to the Ã
position.
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.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
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 the Tposition, the
daytime running lamps and parking lamps
turn on.
If the engine is running and you turn the light
switch to the Lposition, the manual set-
tings take precedence over the daytime run-
ning 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
(
Ypage 230).
If the engine is running and you turn the light
switch to the TorL position, the man-
ual settings take precedence over the day-
time running lamps.
Low-beam headlamps
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 pa
rticularly useful
function in the event of rain and fog.
XTo switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
XTurn 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.
XTo switch on the fog lamps: turn the key
in the ignition lock to position 2or start the
engine.
XTurn the light switch to LorÃ.

ment cluster lights up.

for several hours. If possible, switch on the
X right or the Wleft standing lamp.
XTo 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.

matically if the vehicle reaches a speed of
above 6 mph (10 km/h) again after a full
brake application.
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:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif 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.
Headlamps fogged up on the inside
Certain climatic and physical conditions may
cause moisture to form in the headlamp. This
moisture does not affect the functionality of
the headlamp.
