Climate control
Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.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 button9 (
page 179).
The indicator lamp on the button goes
out. The cooling function switches off
after a short delay.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press button9 (
page 179) again.
The indicator lamp on the button
comes on.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
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.

193 Controls in detail
Automatic climate control*
The automatic climate control is operation-
al whenever the engine is running. You can
operate the automatic climate control sys-
tem in either the automatic or manual
mode. The system cools or heats the inte-
rior depending on the selected interior
temperature and the current outside tem-
perature.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 A/Cmode is deactivated
(
page 192).
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
on 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 192) to di-
rect the air to air vents in the vehicle interior
that are not in the immediate area of unpro-
tected 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 pollu-
tion) may require replacement of the fil-
ter before its scheduled interval.
A clogged filter will reduce the air vol-
ume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off. The cli-
mate control will then adjust the interi-
or temperature to the set value much
faster.
Keep the air intake grille in front of the
windshield free of snow and debris.
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.
