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
0
6/327 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 25 6/
77 7
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.
