Good visibility
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the
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.Activating

Press buttonF in the climate
control panel (
page 167).
The indicator lamp on the button
comes on.
Deactivating

Press buttonF again.
The indicator lamp on the button goes
out.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before
driving. 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
operating simultaneously and there is
insufficient 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
automatically turns itself back on.

168 Controls in detailClimate controlThe climate control is operational when-
ever the engine is running. You can oper-
ate 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 modeAC
OFF
is selected
(
page 173).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burns or frost-
bite on unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected 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 foot-
well air vents (
page 170).
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
“Opening (Summer opening feature)”
(page 221).
Keep the air intake grille in front of the
windshield free of snow and debris.
