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 defrost-
er as soon as the rear window is clear.
The defroster is automatically deactivated
after approximately 6 to 17 minutes of op-
eration depending on the outside tempera-
ture.Switching on

Press the rear window defroster
switchF in the control panel of the
climate control (
page 175) or the au-
tomatic climate control* (
page 185).
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.
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.
!The rear window defroster cannot be
switched on when the retractable hard-
top 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 operat-
ing 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 au-
tomatically turns itself back on.

173 Controls in detail
Climate control
The climate control is operational whenev-
er the engine is running. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the interior through the air distribution
system.
The air conditioning will not engage (no
cooling) if the ±mode is selected
(page 175).

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 burn or frost-
bite to 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 175).
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.

174 Controls in detailClimate control
iWhen you turn the thumbwheels4
and7 upwards to the first stop, the
fixed center air vents3 and8 and
the adjustable center air vents5
and6 are open.
When you turn the thumbwheels com-
pletely upwards, only the adjustable
center air vents5 and6 are open.
For draft-free ventilation, move the slid-
ers for the center air vents5 and6
to the middle position.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter 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.
When the retractable hardtop is closed,
do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
Keep the air intake grille in front of the
windshield free of snow and debris.

Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

Press air condition on/off switch°
(page 175).
The indicator lamp on the air condition
on/off switch° comes on.
iIf you press the air recirculation
switch, and keep it pressed
and no side window was operated
manually, the side windows will reopen
to their previous position.
iCondensation may drip from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, the vehi-
cle will not be cooled when the weather con-
ditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
