Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: 2-zone Thermatic
4-zone Thermotronic*
Rear-compartment air conditioning*
242-zone Thermatic is an automatic air-condi-
tioning system combining an automatic heat-
ing and ventilation system with a cooling
system. 4-zone Thermotronic is a luxury automatic
air-conditioning system combining an auto-
matic heating and ventilation system with a
cooling system. You can control the air con-
ditioning separately for each zone in the vehi-
cle. The rear-compartment air conditioning
allows a separate temperature setting for the
rear compartment.

Rear-compartment air conditioning is only available in conjunction with 4-zone Thermotronic. Cont

163General notes
2-zone Thermatic controls the temperature of
the vehicle interior and filters out undesirable
substances from the air.
4-zone Thermotronic* controls the tempera-
ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
2-zone Thermatic/4-zone Thermotronic* is
only operational when the engine is running.
Optimum operation is only achieved when
you drive with the side windows and sliding/ tilting sunroof*/panorama sliding sunroof*
closed.
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 109). This will
speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out
pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may obstruct your view
of the traffic situation, thereby causing an
accident. Cont
