Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, 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.

Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
iWhen the air conditioning is switched
off, the outside air supply and circula-
tion are also switched off. Only choose
this setting for a short time. Otherwise
the windows could fog up.

Use temperature control rocker
switches3 and5 (

temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).Increasing

Maximum cooling MAX COOL
If the left and right air distribution controls
as well as the airflow volume control are
set toU and there is a high need for
cooling, the display “MAX COOL” appears
in the front and rear display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof* or tilt/sliding panel*
are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside. This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.Activating

When the outside temperature is below
41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.

G
Never operate the side windows and
tilt/sliding sunroof* or tilt/sliding panel* if
there is the possibility of anyone being
harmed by the opening or closing proce-
dure.
In case the procedure causes potential dan-
ger:
Vehicles with tilt/sliding sunroof: The clos-
ing of the side windows can be immediately
halted by pressing or pulling the respective
window switch. The closing of the tilt/slid-
ing sunroof can be immediately halted by
moving the switch for the tilt/sliding sun-
roof in any direction.
The closing of the side windows and the
tilt/sliding sunroof can be reversed by again
pressing and holding theO button.
Vehicles with panorama roof: The closing of
the side windows and tilt/sliding panel can
be immediately halted by releasing theO
button.
iThe air recirculation mode is activated
automatically:
at high outside temperatures
if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel
If you have turned off the air condition-
ing (page 206) or (
page 207) or
the outside temperature is below 41°F
(5°C), the air recirculation mode will
not switch on automatically.
iIf you keep buttonO pressed, the
side windows and the tilt/sliding sun-
roof* or tilt/sliding panel* will return to
their previous position.
