6. Turn the controller to adapt the air distribu-
tion.
Driver's side:
1 Air to windscreen and side windows
2 Air to the upper body area
3 Air to footwells
Front passenger's side:
4 Air to the upper body area
5 Air to footwells
Pressing the AUTO button cancels the air
distribution settings at the control dis-
play, and vice-versa.<
Switching cooling function on and off
Air is cooled and dried when the
cooling function is switched on,
then reheated to suit the tempera-
ture setting. Depending on weather conditions,
the windscreen may fog over momentarily
when the engine is started.
The cooling function is switched on automati-
cally in the AUTO program. The interior can
only be cooled when the engine is running.
Maximum cooling effect
At outside temperatures above
06/327 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
The automatic air-conditioning system
switches to the lowest temperature and oper-
ates in recirculated-air mode. Air flows at maxi-
mum rate only from the outlets for the upper
body area. You should therefore open these
outlets for maximum cooling.
Automatic Air Recirculation Control
AUC/recirculated-air mode
If the air outside the car has an
unpleasant odour or contains pol-
lutants, the supply to the interior of
the car can be shut off. The air inside the car is
then recirculated. In the AUC mode, a sensor
detects pollutants in the outside air and shuts it
out automatically.
Three operating modes can be obtained in suc-
cession by pressing this button repeatedly:
> LED off: ambient air is constantly entering
the car.
> Right-hand LED on, AUC mode: the system
will identify pollutants in the ambient air and
shut off the ambient air supply if necessary.
> Left-hand LED on, recirculated-air mode:
the ambient air supply is permanently shut
off.
If the windows fog over in the recircu-
lated-air mode, switch it off and, if neces-
sary, increase the air volume.
The recirculated-air mode should not be used
continuously for lengthy periods, as the quality
of the air inside the car will otherwise gradually
deteriorate.<
Residual heat
Heat from the engine is stored and
used to heat the car's interior, for
instance when waiting at a level
crossing.
The function can be switched on whenever the
following conditions are met:
> Up to 15 minutes after the engine has been
switched off
> The engine is at operating temperature
> Battery voltage is sufficient
> The outside temperature is below 256/
777
The LED lights up when the function is
switched on.
Following radio readiness, you can adjust the
interior temperature, air flow rate and air distri-
bution.
