Rear window defroster
Turn the SmartKey in starter switch to
position2.
Activating
Press button F in the control panel
of the climate control.
The indicator lamp in the button comes
on.
Deactivating

Press button F in the control panel
of the climate control.
The indicator lamp in the button goes
out.
!Heavy accumulation of snow and ice
should be removed before activating
the defroster.
The defroster is automatically turned
off after approximately 6-17 minutes of
operation depending on the outside
temperature and vehicle speed.
If several power consumers are turned
on simultaneously, or the battery is
only partially charged, it is possible that
the defroster will automatically turn it-
self off.
When this happens, the indicator lamp
inside the switch starts blinking.
As soon as the battery has sufficient
voltage, the defroster turns itself back
on.
iThe rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, turn off the de-
froster as soon as the rear window is
clear.

158 Controls in detailClimate controlThe climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. 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
(
page 162).
Setting the temperature
Use temperature controls2 and3 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).
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 159).
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.
