enter the vehicle.
NOTE: Prolonged air recirculation can worsen the air
quality and lead to fogging up of the windows. Shut off
air recirculation as soon as possible.
Only with automatic heat regulation and regulated air
conditioning (Optional):
Air recirculation is automatically switched off after
about 15 minutes or when engine is shut off.
Heating1. Set the airflow control (2) as required.
2. Set the temperature control (1) as required.

De-Fogging and De-Icing The Front Windows1. Set the airflow control (2) to position 3 or 4.
2. Set the temperature control (1) to P .
3. Set the air distribution control (3) to Z.
4. Switch off air recirculation, refer to "Air
Recirculation" . NOTE:
On vehicles with auxiliary heater (water
heater):
The additional heat exchanger in the load
compartment should be switched off to quickly de-fog
and de-ice the windshield and front side windows,
refer to "Auxiliary Heat Exchanger in Load
Compartment".
For how to switch on heater booster mode, refer to
"Heater Booster".
On vehicles with air conditioner (Optional):
At outside temperatures above 41 °F (+5 °C), switch on
the air conditioner for quicker dehumidification, refer
to "Air Conditioning, Regulated".

122 UNDERSTANDING YOUR INSTRUMENT PANELResidual Engine Heat Utilization (REST)
The REST switch (1) is located on the
center section of the dashboard.
The residual engine heat utilization
system can be used to keep the
vehicle interior warm for some time
after the engine is switched off.
Turn the key to position 0 in the ignition lock or
remove it altogether.
To switch on:
1. Press the residual engine heat utilization switch (1), the indicator lamp (2) lights up.
The blower will run at speed 1 regardless of the
setting of the airflow control.
2. Set the temperature control as required, refer to "Heating, Ventilation".
To switch off:
Press the residual engine heat utilization switch (1)
again, the indicator lamp (2) goes out. The residual engine heat utilization is automatically
switched off if:
1. the key is turned to position 2 in the ignition lock,
2. after about 30 minutes,
3. if the battery voltage is too low.
AIR CONDITIONING, REGULATED (OPTIONAL)
The air conditioning switch (1) is
located on the center section of the
dashboard.
The air conditioning can be used to
cool or dehumidify the air in the
vehicle. The selected temperature is
reached as quickly as possible and
then held constant.
The air conditioning is only operational when the
engine is running.

To switch on:
Press switch (1), the indicator lamp (2) in the switch
lights up.
To switch off:
Press switch (1) again, the indicator lamp (2) goes out.
NOTE : Run the air conditioning at least once a month
for about 10 minutes.
It is possible that the air conditioning will
automatically switch off at outside temperatures below
41 °F (+5 °C). Dehumidification is then also not
possible.
Condensation may emerge from the underside of the
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
Tempmatik. If the interior temperature falls below
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.

124 UNDERSTANDING YOUR INSTRUMENT PANELNOTE: Open and adjust the air vents as required, refer
to "Side Air Vents and Center Air Vents" .
At high outside temperatures, a better cooling
performance is achieved by switching on air
recirculation. For note on air recirculation, refer to "Air
Recirculation" .
Dehumidification
(on Vehicles with Air Conditioning)1. Set the airflow control (2) to position 3 or 4.
2. Set the temperature control (1) as required.
3. Set the air distribution control (3) between X
