Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on
even during the daytime. Therefore, your vehicle
is equipped with special daytime running lamps.
In some countries, operation of the headlamps
varies due to legal requirements 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
(
Ypage 206).

fog, snow or spray):
RSmartKey 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 activated
the Daytime Running Lightsfunction via
the on-board computer, the daytime running
lamps or the parking lamps and the low-beam
headlamps are switched on or off automati-
cally depending on the brightness of the ambi- ent light.
XTo switch on automatic headlamp mode:
turn the light switch to Ã.
Canada only:
The daytime running lamps improve the visibility
of your vehicle during the day. The daytime run- ning lamps function is required by law in Can-
ada. 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 sta-

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 head-
lamps switch on when the ignition is switched on and the light switch is set to the Lposition.
This is a particularly useful function in the event
of rain and fog.
XTo switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to posi- tion 2or start the engine.
XTurn the light switch to L.

ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. 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.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button goes out.
RVehicles with 3-zone automatic climate con-
trol: use the residual heat function if you want
to heat or ventilate the vehicle interior when
the ignition is switched off. The residual heat
function can only be activated or deactivated with the ignition switched off.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa- city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, deactivate the cooling with air-dehumidification function only briefly.
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.
