nabout using THERMATIC
automatic climate control
The following contains notes and recommen-
dation sonoptimum use of THERMATIC auto-
matic climate control.
R Activat eclimate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 22 †.
R Only use the demisting func tion briefly until
the windscreen is clea ragain.
R Only use the air-recirculation mode briefly,
e.g. if ther eare unpleas anto utside odours
or when in atunnel. The windows could
otherwis emist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE func tion to adopt the tem-
peratur esettings on the driver' sside for
the front-passenger side as well. The indi-
cator lamp above the ábutton goes
out. 138

the windscreen is clear again.
R Only use the air-recir culation mode briefly,
e.g. if there are unpleasant outside odours
or when in atunnel. The windows could
otherwis emist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE func tion to adopt the tem-

WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air dehumidification function
is only available when the engine is running.

maintained automatically at
aconstan tlevel.
The system automatically regulates the tem-

Automatic mode will achieve optimal opera-
tion if cooling with air dehumidification is also
activated. If desired, cooling with air dehu-
midification can be deactivated.
In the rear compartment ,you can also switch
climate control for the rea rseats to automatic
