Good visibility
Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after
approximately 6 to 17 minutes of
operation depending on the outside tem-
perature.
Switch on the ignition (page 39).Activating
Press button1 on the climate con-
trol panel (
page 220) or the automat-
ic climate control* panel (
page 234).
The indicator lamp on the button
comes on.
Deactivating
Press button1 once more.
The indicator lamp on the button goes
out.
!With the sunshade raised and the respective
door window open, the sunshade could disen-
gage and snap back when driving at high vehicle
speeds, e.g. on highways, and damage the
retractor. You should therefore always either
close the door window or lower the sunshade
when driving at high speed.
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, too
many electrical consumers are operating simul-
taneously and there is insufficient voltage in the
battery. The system responds automatically by
switching the rear window defroster off.
As soon as the battery has sufficient voltage, the
rear window defroster switches back on auto-
matically.

221 Controls in detail
Climate control
The climate control is operational whenev-
er the engine is running. You can operate
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 en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
(
page 228).
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 to unpro-
tected skin in the immediate area of the air
vents.
Always keep sufficient distance between un-
protected parts of the body and the air
vents. If necessary, use the air distribution
controls (
page 220) 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 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 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 254). 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.
