Air conditioning
Air is cooled and dried
when the air conditioning
is switched on, then is heated back up
to suit the temperature setting.
Depending on weather conditions, the
windscreen may fog over momentarily
when the engine is started. Switching
on the air conditioning system reduces
this effect.
Moisture condensate forms in the
air conditioning and is discharged
underneath the car. Traces of water on
the ground are therefore normal.

Maximum cooling effect
This program enables you
rapidly to achieve
maximum cooling effect when the
engine is running, at outside tempera-
tures of approx. 5
6
upwards.
The temperature displays 9 jump to
16
6
, the system switches to the recir-
culated-air mode and air emerges at
the maximum flow rate from the ventila-
tion grilles only. Be sure to keep these
grilles open when you select this
program.
Automatic Recirculated Air
Control (AUC)
If the air outside the car
has an unpleasant odour
or contains pollutants, you can shut off
the supply to the interior of the car
temporarily. The air inside the car is
then recirculated. Obtain the desired
operating mode by pressing the button
as often as necessary.
>
Indicator lights off: airflow from
outside the car
>
Left indicator light on  AUC opera-
tion: the system identifies pollutants
in the outside air and shuts off the
supply if necessary. The air inside the
car is then recirculated.
After this, the automatic system
switches between outside air supply
and recirculated air according to the
available air quality
>
Right indicator light on: the outside
air supply is permanently shut off.
The air inside the car is recirculated.
If your car has a multifunctional steering
wheel with recirculated air switch (see
page 20), you can use it to change
between "Off" and the recirculated air
mode (or between AUC and the recircu-
lated air mode).
If the windows mist up in recircu-
lated mode, switch this mode off
and, if necessary, also increase the air
supply.
