General notes
The vehicle is equipped with the Thermatic
air-conditioning system. Thermatic combines
an automatic heating and ventilation system
with a cooling system.
Thermatic controls the temperature and the
humidity of the vehicle interior and filters out
undesirable substances from the air.
Thermatic is only operational when the
engine is running. Optimum operation is ach-
ieved only when you drive with the side win-
dows and sliding/tilting sunroof* closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 85). 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 pol-
len. 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

Air conditioning
124 Switching the air conditioning on/off
i When the air conditioning is switched off,
the air supply and air circulation are also
switched off. Only select this setting briefly,
otherwise the windows may mist up.
Thermatic X
Make sure that the key is in position 2in
the ignition lock or that the engine is run-
ning.
X To activate: turn thumbwheel 1clock-
wise to the desired position (apart from the
0 position) (Y page 122).
X The previously selected settings come into
effect again.
X To deactivate: turn thumbwheel 1anti-
clockwise to position 0(Y page 122). Switching cooling with air dehumidi-
fication on/off
The "cooling with dehumidification" function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. This prevents the windows from misting
up. G
Risk of accident
If the "cooling with air dehumidification"
function is deactivated, the air inside the
vehicle will not be cooled (during warm
weather) or dehumidified. The windows
could mist up more quickly. This may pre-
vent you from observing the traffic condi-
tions, thereby causing an accident. H
Environmental note
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. X
To activate: press the9button.
The indicator lamp in the 9button lights
up.
X To deactivate: press the9button.
The indicator lamp in the 9button goes
out. Controlling the air conditioning auto-
matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
To do so, the system automatically regulates
the temperature of the dispensed air, the air-
flow and the air distribution. The "cooling with
air dehumidification" function is on.
X Make sure that the engine is running.
X Set the desired temperature.
X To activate: press theUbutton
(Y page 122).
The indicator lamp in the Ubutton
comes on. Automatic air distribution and
airflow are activated.
X To deactivate: press theUbutton.
The indicator lamp in the Ubutton goes
out. Automatic air distribution and airflow
are deactivated. Cont

Different temperatures can be set for the
driver's and front-passenger sides.
X To increase/reduce: turn thumbwheels
2 and 3clockwise or anti-clockwise .
Only change the temperature setting in
small increments. Start at 22 †.
i The temperature of the air from the rear-
compartment air vents and the centre air
vents is the same.
i If you turn the temperature thumbwheel
on one side of the vehicle fully to the right
or left, you will increase or reduce the tem-
perature on the other side of the vehicle at
the same time. Adjusting the air vents
G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Setting the centre air vents Centre air vents
