Important safety notes

G WARNING
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
could 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.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
keep the air inlet grille on the hood and in
R
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
never cover the air vents or air intake grills
R
in the vehicle interior.

For virtually draft-free ventilation, adjust
the sliders of the air vents to the center
position.

Setting the glove box air vent
When automatic climate control is activated,

cool its contents. The level of airflow depends
on the airflow and air distribution settings.
At high outside temperatures, open the air
vent and activate the "cooling with air
dehumidification" function.
