Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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.
i Read the information on qualified
specialist workshops: (Y page 27).Exterior lighting
General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. Driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again. Setting the exterior lighting
Setting options Exterior lighting can be set using:

mode: turn the light switch to 0006.
Only for Canada:
The daytime running lamps improve the
visibility of your vehicle during the day. The
daytime running lamps function is required by
law in Canada. It cannot therefore be

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.

stationary and in high ambient light: if you
turn the light switch to 0016, you turn on the
daytime running lamps and parking lamps.
If the engine is running and you turn the light
switch to 000D, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the
visibility 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 274).
If the engine is running and you turn the light
switch to 0016or000D, the manual settings
take precedence over the daytime running

if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp above the 0004button goes

Activating/deactivating cooling with
air dehumidification
Points to observe before use If you switch off the cooling function, the
vehicle will no tbe cooled when weather
conditions are warm. The windows can fog up
more quickly. Only deactivate the cooling
with air dehumidification function for a short
time to preven tthe windows from fogging up.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
Activating/deactivating Example:
0007button
X To activate: press the0007/0005 button.
The indicator lamp in the 0007/0005
button lights up.
X To deactivate: press the0007/0005
button.
The indicator lamp in the 0007/0005
button goes out. The cooling with air
dehumidification function has a delayed
switch-off feature. Problems with the "cooling with air
dehumidification" function When you press the
0007button, the
indicator lamp in the button flashes three
times or remains off. You can no longer switch
on the cooling with air dehumidification
function.
X Visit a qualified specialist workshop. Setting climate control to automatic
Points to observe before use If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Only deactivate the cooling
with air dehumidification function for a short
time to prevent the windows from fogging up.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If necessary, cooling with air
dehumidification can be deactivated.
In the rear compartment, you can also switch
climate control for the rear seats to automatic
mode using the 0006button.
