184 Controls in detail
Climate control
The climate control is operational when-
ever the engine is running. You can oper-
ate the climate control system in either the
automatic or manual mode. The system
cools or heats the interior depending on
the selected interior temperature and the
current outside temperature. Nearly all dust particles, pollutants and
odors are filtered out before outside air
enters the passenger compartment
through the air distribution system.
The air conditioning will not engage (no
cooling) if the
A/C mode is deactivated
(
page 189).
Warning!G
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 on unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance
between unprotected pa rts of the body and
the air vents. If necessary, use the air distri-
bution control (
page 186) to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
Warning!G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility an d endangering you and
others.
iSevere conditions (e.g. strong air pollution)
may require replacement of the filter 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, see “Summer opening fea-
ture” (
page 193). The climate control will then
adjust the interior temperature to the set value
much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.

Air conditioning
The cooling function, only operational
when the engine is running, cools the
vehicle interior down to the selected
temperature. The cooling function also
dehumidifies the air in the vehicle interior,

tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.
