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.

Maximum cooling MAX COOL
When operating the automatic climate
control system in automatic modeU
and there is a high need for cooling,
MAX COOL is activated. This provides the
fastest possible cooling of the vehicle’s in-
terior (when retractable hardtop is closed).MAX COOL
will appear in displaye
(
page 192).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the interior.Activating

Press button, (
page 192).
The indicator lamp on the button
comes on.
Warning!
G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 187) is activated, or
press buttonP.
iThe air recirculation mode activates au-
tomatically at high outside tempera-
tures.
The indicator lamp on button, is
not lit when the air recirculation mode
is automatically switched on.
A quantity of outside air is added after
approximately 30 minutes.

The indicator lamp on the button goes
out.
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.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Warning!
G
Never operate the side windows if there is
the possibility of anyone being harmed by
the closing procedure.
In the event that the procedure causes po-
tential danger, the closing of the door win-
dows can be immediately halted by
releasing the, button or by pressing the
respective power window switch.
The closing of the rear side windows can be
immediately halted by releasing the
,button.iIf you press button, and keep it
pressed, the side windows will close.
The closing of the windows can be im-
mediately halted by releasing
button,.
iThe air recirculation mode is deactivat-
ed automatically:

after 5 minutes if the outside tem-
perature is below approximately
41°F (5°C)


after 5 minutes if the air condition-
ing is turned off (
page 200)


after 30 minutes if the outside tem-
perature is above approximately
41°F (5°C)
iIf you press button, and keep it
pressed, the side windows will open.
The opening of the windows can be im-
mediately halted by releasing
