Heating and ventilation
Heating, manual air conditioning system, Climatronic
Introduction
The heating heats and ventilates the vehicle interior. The air conditioning sys-
tem 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 works under the following conditions.
The cooling system is switched on.
The engine is running.
The outside temperature is below 2 ° C.
The blower is switched on.
Fogging is prevented when the cooling system is switched on.
It is possible to boost the effectiveness of the cooling system by briefly acti-
vating the air recirculation system » page 114.
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 should be turned off about 10 minutes before the end of
the journey.
▶
Once a year, the air conditioning should be disinfected by a specialist garage.
WARNING
■
The blower should always be on to prevent the windows from misting.
Otherwise there could be an accident.
■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
Notice
■
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.
■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.
