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.
Switch on the ignition (page 36).Activating
Press buttonF or1 in the
climate control panel (
page 189) or
automatic climate control panel
(
page 199).
The indicator lamp on the button
comes on.
Deactivating
Press buttonF or1 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 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 on
again.

Climate control
The 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 A/C mode is deactivated
(
page 196).
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 on unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion control (
page 189) 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 252). 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.
Do not obstruct air flow by placing objects on the
air flow-through exhaust slots below the rear
window.

ume and air distribution switches off.
Warning!G
When the climate control is switched off, the
outside air supply and circulation are also
switched off. Only choose this setting for a
short time. Otherwise the windows could
fog up, impairing visibility and endangering
you and others.
iWhen operating the climate control system
in automatic mode, you will only rarely need to
adjust the temperature, air volume and air distri-
bution.
In automatic mode, the dehumidify function is
switched on when the system is cooling. If nec-
essary, this function can be switched off by
pushing the2 button.
