the desired program is shown on
the Control Display.
1 Air toward the windshield and side windows
2 Air for the upper body

Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
This function is only available when the engine
is running.
The cooling function helps to avoid condensa-
tion on the window surfaces or to quickly
remove them.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program.

Maximum cooling

Maximally cooled air is obtained as
quickly as possible at an outside
temperature above approx. 327/
06 and with the engine running.
The automatic climate control switches into the
recirculated-air mode at the lowest tempera-
ture. The maximum air volume flows out of the

You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system
LED off: outside air flows in continuously.
Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
Right LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
continuously.<
Pressing the right side switches on
the residual heat utilization when
the following conditions are met:
Up to 15 minutes after switching off the
engine
With the engine at operating temperature
With sufficient battery voltage
At an outside temperature below 777/
