Please observe the following notes to ensur e
that the air can flow freely through the ai r
vents:
R Keep the air inlet on the bonnet free of
blockage, such as ice or snow, to guarantee
the supply of fresh air into the vehicle inte-
rior.
R Never cover the vents or air inlet and outlet
grilles in the vehicle interior. Opening/closing the air vents

Thermatic

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

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and

Risk of accident
If you deactivate the cooling function with
air dehumidification, the vehicle will not be
cooled in warm weather and the air will not
be dehumidified. The windows could mis t
up more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident. H
Environmental not
e
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
i Condensation may drip from the under-
side of the vehicle when Thermatic is in
cooling mode.
Cooling with dehumidification is operational
when the engine is running, and cools accord -
ing to the interior temperature selected. The
air inside the vehicle is also dried, thereby
preventing the windows from misting up.

event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the ris k
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
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 .
