Heating and air conditioning system
WARNING
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and misting. Please familiarize yourself about
how to correctly operate the heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
You should not leave recirculated air mode on over a longer period of
time, as "stale" air may result in fatigue in the driver and occupants, divert
your attention and also cause the windows to mist up. The risk of having an
accident increases. Switch recirculated air mode off as soon as the windows
begin misting up.
Note
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on
at least once a month for approximately 5 minutes at the highest blower stage - also
during the cold season of the year - in order to remove such odours. Also open a
window for a short time.
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte-
rior of the vehicle forms deposits in the evaporator of the air conditioning system.
This produces a permanent odour when the air conditioning system is operating
which can only be eliminated through considerable effort and expense (replace-
ment of compressor).
The used air streams out through the air removal openings in the luggage
compartment.
On vehicles equipped with a factory-fitted radio* or navigation*, the informa-
tion of the Climatronic is also shown on the display. This function can be switched
off, see operating instructions of the radio* or the navigation system*.
