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 ( Y page 27).
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 ( Y page 118)
R the on-board computer ( Y page 231)

Operation
1 WLeft-hand standing lamps
2 XRight-hand standing lamps
3 TParking lamps, license plate and
instrument cluster lighting
4 ÃAutomatic headlamp mode, control-
led by the light sensor
5 LLow-beam/high-beam headlamps
B RRear fog lamp
C NFog 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 if
you: 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 .
116Exterior 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 1 in 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" func-
tion via the on-board computer, the day-
time 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 231). If the engine is running and you turn the light
switch to T or L , the manual settings
take precedence over the daytime running
lamps.
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 2 or start the engine.
X Turn the light switch to L.
The green L indicator 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 L or à .

ment cluster goes out.
Only vehicles with front fog lamps have the
fog lamps function.
Rear fog lamp
The rear fog lamp improves visibility of your
vehicle for the traffic behind in the event of
thick fog. Please take note of the country-
specific regulations for the use of rear fog
lamps. X To switch on the rear fog lamps: turn the
SmartKey in the ignition lock to position 2
or start the engine.

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 T parking lamps
for several hours. If possible, switch on theX right or the W left standing lamp.
X To switch on: turn the light switch to T.
The green indicator lamp in the instrument cluster lights up.
Standing lamps
Switching on the standing lamps ensures the corresponding side of the vehicle is illumina-
ted. X

SmartKey is not in the ignition lock or it is in position 0.
X Turn the light switch to W (left-hand side
of the vehicle) or X (right-hand side of

air dehumidification
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and

Setting climate control to automatic
General notes
In automatic mode, the set temperature is
maintained automatically at a constant level. The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi- cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
