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 » page 104.
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.
WARNING (Continued)
■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
■
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
temperature 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 or the Climatronic is to
be carried out by a specialist company.
CAUTION
■
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.
Note
The used air streams out through the vents in the luggage compartment.
