(automatic mode)i Switch on the automatic mode. The
indicator lamp in button à comes on.(Y page 179)Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the tilt/sliding
panel closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode ( Y page 179) is
deactivated.GWarning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
XKeep the air intake grille in front of the
windshield free of snow and debris.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” ( Y page 97). The climate
control will then adjust the interior
temperature to the set value much faster.

Deactivating the climate control
systemGWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time. Otherwise the
windows could fog up, impairing visibility and
endangering you and others.

XPress button Ã.
The indicator lamp in the button comes on.
Air volume and air distribution are adjusted
automatically.
Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.
XPress button ¿.
The indicator lamp in the button goes out.
The cooling function switches off after a
short delay.
Activating
Moist air can fog up the windows. You can
dehumidify the interior air with the air
conditioning.
XPress button ¿.
The indicator lamp in the button comes on.
i The evaporator will be vented when the
air conditioning has been in use.
Approximately 1 hour after locking the
vehicle, the blower switches on
automatically. The blower will run for
30 minutes at its lowest level. The blower
noise is normal and not an indication of a
malfunction. When you unlock the vehicle
in the meantime, venting will be
interrupted. If the vehicle battery is low,
automatic evaporator venting will not occur
in order to preserve the battery.
Automatic mode
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
In automatic mode, cooling with
dehumidification is switched on. This function
can be switched off if necessary.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up

Setting temperature
You can adjust the air temperature on each
side of the passenger compartment. You
should raise or lower the temperature setting
in small increments, preferably starting at
72‡ (22†).

XIncreasing/decreasing: Turn

Adjusting air vents
GWarning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
XKeep the air intake grille in front of the
windshield free of snow, leaves, sticks, and
any other debris.
XAlways keep all air vents and grilles in the
passenger compartment free from
obstruction.
iFor draft-free ventilation, move the
adjustable center and side air vents to the
middle position.
