automatic mode.
XSet the temperature to 72 ‡ (22 †).
iOnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear again.
iOnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or when
in a tunnel. The windows could otherwise fog
up, since no fresh air is drawn into the vehicle in air-recirculation mode.

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, only deactivate the "Cooling with air-dehumidification" function briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The air
inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal
and not a sign that there is a malfunction.
Activating/deactivating
XPress the ¿rocker switch up or down.

The system automatically detects whether the
soft top is open or closed and automatically
adjusts the air settings depending on the soft
top status.

Rear window defroster
General notes
The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.

ProblemPossible causes/consequences and MSolutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated.The battery has not been sufficiently charged.
XSwitch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.

General notes
You can also temporarily deactivate the flow of
fresh air manually if unpleasant odors are enter-
ing the vehicle from outside. The air already
inside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.
