Your heater and ventilation controls
Accident risk!
You are strongly recommended to
adhere to the heating system settings
described on the next few pages. The
windows could otherwise fog over. You
could otherwise cause an accident
because of the resulting reduced
visibility.
Adjusting the temperature
The further you push the knob (A) to the
right hand side, the warmer the flow of
air will be.
How to adjust the recirculated air or
fresh air flow
Accident risk!
Use the recirculated air mode
only for brief periods. The windows
could otherwise fog over.
The oxygen content in the passenger
compartment will be depleted. This
reduces concentration and thus
increases the danger of fatigue.
Heater/ventilation
Select the upper position for fresh air
(A).
> The air is drawn in from outside the
car.
