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.

g128 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 ai r
vents:
R Keep the air inlet between the windscree n
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.

vents in the central position to provide vir-
tually draught-free ventilation. Setting the centre air vents Centre air vent

skin in the immediate vicinity of the vents.
Make sure that you reduce the heater out-
put in time. 1
