vehicle.
The air conditioner only uses the refrigerant R-134a.
This refrigerant does not damage the earth’s ozone
layer.
Climate Control (on Vehicles with Air Conditioning)1. Set the airflow control (2) to position 1 to 4. Position 4 gives maximum cooling.
2. Set the temperature switch (1) as required (The interior temperature is regulated by the

the preset temperature, warm air is automatically
supplied).
3. Set the air distribution control (3) to h.
4. To switch on air conditioning, press switch (4).
WARNING!
While driving, deactivate the air conditioning
only temporarily to prevent window fogging.

HEATER BOOSTER
The switch (1) for activating the
heater booster system is located in
the center section of the dashboard.
The heater booster system can be
switched on while the vehicle is
being driven to help the engine to
reach its normal operating
temperature more quickly, which
will help to heat up the passenger compartment as
quickly as possible when the heating is switched on. To switch on with the engine running:
Press switch (1), the indicator lamp (2) lights up.
To switch off:
Press switch (1) again or switch the engine off. The
heater booster will then switch to run-on mode (about
2minutes).
NOTE:
When the vehicle is being driven and a coolant
temperature of over 185 °F (+80 °C) is reached, the
heater booster system will switch to regulation mode.
If the coolant temperature drops to below 167 °F
(+75 °C) with the heater booster system switched on,
heat output is increased again.
If the key is turned to position 0 in the ignition lock
(run-on for about 2 minutes), the last setting selected at
switch (1) is retained when the engine is restarted
(memory function).
The operation of the heater booster system is usually
not required at outside temperatures above 41 °F
(+5 °C).
