Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: Heatmatic
2-zone Thermatic* Thermotronic
* Heatmatic is a heating and ventilation system
without a cooling system.
i
The design of the control panel and the
functions of Heatmatic are identical to that
of 2-zone Thermatic.
Exception: 2-zone Thermatic has the addi-
tional "A/C" function 9. 2-zone Thermatic combines a heating and
ventilation system with a cooling system.
i
The design of the control and the func-
tions of 2-zone Thermatic are identical to
that of Heatmatic.
Exception: 2-zone Thermatic has the addi-
tional "A/C" function 9. The Thermotronic automatic air-conditioning
system combines an automatic heating and
ventilation system with a cooling system. You
can control the air conditioning separately for
the driver's and front-passenger sides.Controls

g 119General notes
2-zone Thermatic*/Thermotronic* controls
the temperature and the humidity of the vehi-
cle interior and filters out undesirable sub-
stances from the air.
Heatmatic/2-zone Thermatic*/
Thermotronic* is only operational when the
engine is running. Optimum operation is only
achieved when you drive with the side win-
dows closed. i
Ventilate the vehicle for a brief period
during warm weather. 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 vie w
of the traffic situation, thereby causing an
accident . Cont

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 mistin g
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 window s
could mist up more quickly. This may pre -
vent you from observing the traffic condi-
tions, thereby causing an accident. Controls

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.
The "cooling with air dehumidification" func-
tion is only available with 2-zone Thermatic*
or Thermotronic* .

ification has a delayed switch-off feature. Controlling the air conditioning auto-
matically
Only Thermotronic *features the "control air
conditioning automatically" function .
In automatic mode, the set temperature is
maintained at a constant level fully automat-
ically. To do so, the system automatically
regulates the temperature of the dispensed
air, the airflow and the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary ,
cooling with air dehumidification can be deac-
tivated.
