Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.
Activating
Press buttonFon the climate con-
trol panel (
page 173) or the automat-
ic climate control panel (

!Always guide the sunblind by hand. Do
not let it snap back, as the retractor
could be damaged.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

187 Controls in detail
Automatic climate control*
The automatic climate control is a 4-zone
intelligent climate control system. Your ve-
hicle interior is divided into 4 zones.With the help of a sun sensor, the automat-
ic climate control determines the relation
of the sun to the vehicle and automatically
adjusts the inside temperature for every in-
dividual zone.
You can set the temperature for each of
the 4 zones separately. These settings can
be assigned to a SmartKey and stored in
memory (
page 152).
The automatic climate control is operation-
al whenever the engine is running. It cools
the vehicle’s interior according to the an-
gle and intensity of the sun’s rays, the out-
side temperature and the selected
temperature. You can operate the climate
control system in either the automatic or
manual mode.
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 burn or frostbite to 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
(page 186) to direct the air away from the
footwell air vents.

188 Controls in detailAutomatic climate control*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 186).
Setting the temperature
Use temperature control3 for the left
side or5 for the right side 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
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.
iSevere 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.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.
