Important information
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled (in warm weather) or dehumidi-
fied. The windows could fog up more quickly.
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 appear on the underside of
the vehicle when in cooling mode. This is normal
and not a sign that there is a malfunction.

Adjusting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable. On vehicles with a rear-compartment air-condi-
tioning system, you can also adjust the air vents
in the roof duct.
iFor virtually draft-free ventilation, adjust the
sliders of the center air vents to the center
position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
Rnever cover the vents or the ventilation grilles
in the vehicle interior.

Operation with the remote control
Important information
You can switch the auxiliary heating on/off and
set the operating duration using the remote con-
trol. You can use up to 4 remote control units on
the vehicle. These must be synchronized for the
receiver in your vehicle (
Ypage 109).
The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
Rsources of interference
Rsolid objects between the remote control and
the vehicle
Rthe remote control being in an unfavorable
position in relation to the vehicle
Rtransmitting from an enclosed space

Replacing the remote control battery
GWARNING
Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatalinjury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention
immediately.
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
If the indicator lamp on the remote control
flashes red rapidly, the remote control battery is
discharged. You should replace the remote con-
trol battery.
You need a battery of the type CR2430, which
can be obtained at any qualified specialist work-
shop.
