R
Only use demisting mode until the misted
windscreen is clear again.
R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant odours or in dusty con-
ditions. The windscreen and the window may
otherwise mist up as the flow of fresh air is
deactivated and the air inside the vehicle is
circulated.

Automatic climate control is a combination of an
automatic heating and ventilation system and a
cooling system. The automatic climate control
can also control an auxiliary heating system
and/or an auxiliary air-conditioning system.
Recommendations for optimal climate control:
R
Switch on automatic mode. All basic func-
tions are controlled automatically and the
cooling function is activated. The indicator
lamp in the
Ã
button lights up.
R
Set the temperature to 22 †. Only change the
temperature in small increments.
R
After long journeys, use the residual heat of
the engine to heat the stationary vehicle. The
indicator lamp in the
Á
button lights up.
R
Only use demisting mode until the misted
windscreen is clear again.
R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant odours or in dusty con-
ditions. The windscreen and the window may
otherwise mist up as the flow of fresh air is
deactivated and the air inside the vehicle is
circulated.
Switching the cooling with air dehu-
midification function on/off
General notes
For vehicles with an air-conditioning system or
automatic climate control you can cool down
and dry the air inside the vehicle during warm
weather to a set temperature.
Depending on the equipment, the "cooling with
air dehumidification" function can be switched
on with one or two levels.
If the function has been switched on with two
levels, switch off the "cooling" function first to
cool the air inside the vehicle. The indicator
lamp in the
¿
or
Á
button is then lit
green. When necessary, you can also switch on
the "dehumidification" function. The air inside
the vehicle will then also dehumidify and the
windows and the windscreen cannot mist up.
The indicator lamp in the
¿
or
Á
button is
then lit red.
The "cooling" function is more fuel-efficient than
the "cooling with air dehumidification" function.
Only switch on the "cooling with air dehumidifi-
cation" function if the windows and the wind-
screen mist up.
If the function is switched on using one level, you
can only switch on the "cooling with air dehu-
midification" function. The indicator lamp in the
¿
or
Á
button is then lit red.
