103 Controls in detail
Climate control
The climate control is operational whenev-
er the engine is running. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the AC
OFF
mode is selected.

Warning
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burn or frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls to direct the air away from the foot-
well air vents.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.

104 Controls in detailClimate control
Setting the temperature
Use temperature controls5 (
page 103)
to separately 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°F (22°C).Increasing

Turn the temperature control5
slightly upwards.
A red marking will be visible and the
climate control system will correspond-
ingly adjust the interior air tempera-
ture.
iThe selected temperature is reached as
quickly as possible.
Severe 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.
iIf you use the standard settings for
heating or cooling the passenger com-
partment (
page 102), you will rarely
need to change the temperature, air
volume or air distribution.

Decreasing
Turn the temperature control5
slightly downwards.
A blue marking will be visible and the
climate control system will correspond-
ingly adjust the interior air tempera-
ture.
Adjusting air volume
Use air volume control9 (
page 103) to
adjust the air volume. The following sym-
bols are found on the control:

106 Controls in detailClimate controlAir 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
Press buttonÐ (
page 102).
The indicator lamp on theÐ button
comes on.Deactivating

Press buttonÐ (
page 102).
The indicator lamp on theÐ button
goes out.
The air recirculation mode is deactivated
automatically:


after five minutes if the outside temper-
ature is below approximately 41°F
(5 °C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5 °C)
At outside temperatures above 79°F
(26 °C), the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
Warning!
G
When the outside temperature is below
41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.iThe air recirculation mode is activated
automatically at high outside tempera-
tures.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
