Heating and air-conditioning systems
72
AUTO program
The AUTO program adjusts the air
distribution to the windscreen and
side windows, towards the upper
body area and into the footwell for you. The air
flow and your temperature specifications will be
adapted to outside influences as a result of sea-
sonal changes, e.g. sunlight or window mist.
The cooling function is switched on automati-
cally in the AUTO program.
Adjusting air flow manually
Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it. You can
switch the automatic air flow control back on by
pressing the AUTO button.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic air-conditioning system. All indicators go
out.
Press any button except REST to reactivate the
automatic air-conditioning system.
Automatic Air Recirculation Control
AUC/recirculated-air mode
Set the desired operating mode by
pressing this button repeatedly:
> LEDs off: outside air is con-
stantly entering the car.
>
Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
> Right-hand LED on, recirculated-air mode:
outside air supply is shut off permanently.
The air inside the car is recirculated.
You can activate/deactivate recirculated-air
mode by means of a button
*
in the steering
wheel, see page 9 .
If the windows fog over in the recircu-
lated-air mode, switch it off and, if neces-
sary, increase the air flow rate.
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.

Using residual heat
The heat stored in the engine is
used to heat the car's interior, for
instance when waiting at a level
crossing.
You can use this function for up to 15 minutes
after switching off the engine if it is warm and
the battery is sufficiently well charged. The out-
side temperature must be below 25
6 (77 7 ).
The LED in the button comes on if these condi-
tions are met and the function is activated.
Defrosting and demisting windows
This program removes ice and
condensation quickly from the
windscreen and from the front side
windows. When the program is switched on, the
LED comes on.
Switching cooling function on and off
When the cooling function is on, air
is cooled and dried, then reheated
according to the temperature set-
ting. Depending on weather conditions, the
windscreen may fog over momentarily when
the engine is started.
The cooling function can be activated only
when the engine is running it is switched on
automatically along with the AUTO program.
Rear window heating
When the rear window heater is
switched on, the LED comes on.
The heater switches off automati-
cally after a certain time.
