185 Controls in detail
Automatic climate control
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current 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.
Adjusting the temperature
Use temperature controls6 andb 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 outer adjustment ring slightly
to the right.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite on unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected 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 footwell air vents
(page 187).
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.iIf 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.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

186 Controls in detailAutomatic climate controlDecreasing
Turn the outer adjustment ring slightly
to the left.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Adjusting the temperature for the
center and side air vents
When outside temperatures are low, you
can manually raise the air temperature for
the center and side air vents. The
controls2 are located between the cen-
ter air vents (
page 182).
Turning on warm air

Press the left button (red).
The indicator lamp on the button
comes on. Warm air will enter from the

Maximum cooling MAXCOOL
If the left and right air distribution controls
as well as the airflow volume control are
set to U and there is a high need for
cooling, MAXCOOL is activated.
This provides the fastest possible cooling
of the vehicle interior.

air in the passenger compartment.Activating

Press button , (
page 184).
The indicator lamp on the button
comes on.
iThese settings should only be selected
for a short time.
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.
Warning!
G
Never operate the windows if there is the
possibility of anyone being harmed by the
closing procedure.
In the event that the procedure causes po-

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 conditioner
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
