General notes Thermatic is only operational when the
engine is running. Optimum operation is only
achieved when you drive with the side win-
dows and sliding/tilting sunroof*/panorama
sliding sunroof* closed .
You can allow the air-conditioning system to
adjust automatically or you can adjust it man-
ually.
In automatic mode, Thermatic cools or heats
the vehicle interior according to:
R The selected temperature
R The outside temperature
R The intensity of the sunlight
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 111). This
helps you to achieve the desired interior
temperature more quickly.
The integrated filter filters out most particles
of dust and completely filters out pollen.
i A clogged filter reduces the amount of ai r
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Service Booklet. As it depends on envi- ronmental conditions, e.g. heavy air pollu-
tion, the interval may be slightly shorter
than stated in the Service Booklet. G
Risk of accident
Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise mist up. This may
prevent you from observing the traffic con-
ditions, thereby causing an accident. Activating/deactivating Thermati

functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.

to the usual airflow noises when the slid -
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior .
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises .
i It is also possible to open and close the
sliding/tilting sunroof from the outsid e
