defroster as soon as the rear window is
clear. The defroster is automatically
deactivated after approximately
6 to 17 minutes of operation depending on
the outside temperature.

G
Any accumulation of snow and ice should be
removed from the rear window before
driving. Visibility could otherwise be
impaired, endangering you and/or others.
!
If the rear window defroster switches off too
soon and the indicator lamp starts flashing, this
means that too many electrical consumers are
operating simultaneously and there is insuffi-
cient voltage in the battery. The system re-
sponds automatically by deactivating the rear
window defroster.
As soon as the battery has sufficient voltage, the
rear window defroster automatically switches
back on automatically.

187 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.
The air conditioning will not engage (no
cooling) if the ±mode is activated
(
page 194).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents. Always keep sufficient dis-
tance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution controls (
page 190) to di-
rect 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
pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and/or others.
i
Severe 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. The automatic 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.
