Good visibility
Switching on
Press the rear window defroster
switchF in the control panel of
the climate control (
page 174) or
the automatic climate control*
(
page 184).
The indicator lamp on the rear window
defroster switchF comes on.Switching off
Press the rear window defroster
switchF again in the control panel
of the climate control or the automatic
climate control*.
The indicator lamp on the rear window
defroster switchF goes out.
!The rear window defroster cannot be
switched on when the retractable hardtop is
open. The indicator lamp starts flashing if the
hardtop is open.

Close the retractable hardtop first.
The rear window defroster can be switched on
again.
!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
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.

174 Controls in detail
Climate control
Climate control panel
The climate control is operational when-
ever the engine is running. 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
enters the interior through the air distribu-
tion system.
The air conditioning will not engage (no
cooling) if the A/Cmode is deactivated
(
page 174).

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 unprotected parts of the body and
the air vents. If necessary, use the air
distribution controls (
page 174) to direct
the air to air vents in the vehicle interior
that are not in the immediate area of un-
protected skin.
Warning!G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.

Climate control
Switching climate control system
on/off
Switching off
Set air volume control2 (page 174)
to position0.
Switching on
Switch on the ignition (page 37).
Set air volume control2 to any speed
(
page 174).
The previous settings are once again in
effect.
Setting the temperature
Use temperature controls1 and4
(
page 174) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
The climate control will adjust to the set
temperature as fast as possible.
Increasing
Turn temperature control 1
and/or4 (
page 174) slightly
clockwise.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
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. 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.
When the retractable hardtop is closed, do not
obstruct air flow by placing objects on the air
flow-through exhaust slots below the rear
window.
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.
