Introduction
This chapter contains information on the following subjects:
Heating and manual air conditioning
Climatronic (automatic air conditioning)
Climatronic - automatic operation
Air distribution control
Air outlet vents
The heating and air conditioning ventilate and heat the vehicle interior. The air
conditioning system also cools and dehumidifies the vehicle interior.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The cooling system only operates if the following conditions are met.
The cooling system is switched on.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower is switched on.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The cooling system prevents the windows from misting up during
the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect

Health protection
To reduce health risks (e.g. common colds), the following instructions for the
use of the cooling system are to be observed.
›
The difference between the indoor temperature and the outdoor air temper-
ature should not be greater than about 5 ° C.
›
The cooling system is to be turned off about 10 minutes before the end of
the journey.
›
Once a year, a disinfection of the air conditioner is to be carried out by a spe-
cialist company.
WARNING
For your own safety and that of other road users, ensure that all the win-
■
dows are free of ice, snow and misting. The blower should always be on to
prevent the windows from misting up.
Under certain circumstances, air at a temperature of about 5 °C can flow
■
out of the vents when the cooling system is switched on.
CAUTION
111
The air inlet in front of the windscreen must be free of e.g. ice, snow or

■
leaves to ensure that the heating and cooling system operates properly.

leak!
If the coolant temperature is too high, the cooling system is switched off to
