WARNING  
Stale air causes driver fatigue and reduces alertness, which can cause accidents, collisions,  
and serious personal injury.  
Never switch off the fan for a long time because no fresh air will enter the passenger  
compartment.

Please first read and note the introductory information and heed the WARNINGS  
Temperature  
The desired interior temperature cannot be lower than the outside air, because the heating and  
ventilation system cannot cool or dehumidify the air.  
Heating  
Maximum heating output and fast defrosting will only be possible after the engine has reached  
operating temperature.  
Settings for optimum visibility  
Switch off the air recirculation, Air recirculation.  
Set the fan to the desired speed ⇒ꢀfig. 131 (2).  
Turn the temperature knob to the center position (1).  
Open all air vents in the instrument panel, Air vents.  
Turn the air distribution knob (3) to the desired setting.  
Operation  
Please first read and note the introductory information and heed the WARNINGS  
The air conditioner works only when the ignition is switched on. The cooling system for the passenger  
compartment works only when the engine is running and the fan is on.  
The air conditioner is most efficient when the windows and the power sunroof are closed. If the vehicle  
is stationary and the passenger compartment becomes very hot due to sunlight, briefly opening the  
windows and the power sunroof may speed up the cooling process.  
Keep the air intake slots in front of the windshield free of ice, snow, and leaves so that the heating and  
ventilation systems can work properly.  
Settings for optimum visibility  
When you switch on the cooling system, both the temperature and humidity in the vehicle are reduced.  
This will help make passengers feel more comfortable and help keep the windows from fogging up.  
Switch off the air recirculation, Air recirculation.  
Set the fan to the desired speed.  
Turn the temperature knob to the center position.  
Open and adjust all air vents in the instrument panel, Air vents.  
Turn the air distribution knob to the desired setting.  
Push the ꢀꢁꢂbutton to turn on the air conditioner. The indicator light in the button lights up.  
Heating  
Maximum heating output and defrosting performance are not possible until the engine has reached  
operating temperature.  
Air conditioner does not work  
The air conditioner may not switch on for one of the following reasons:  
The engine is not running.  
The fan is switched off.  
The air conditioner fuse has blown.  
The outside air temperature is colder than about +38 °F (+3 °C).  
The air conditioner compressor has been temporarily switched off due to excessive engine coolant  
temperature.  
There is another malfunction in the vehicle. Have the air conditioner checked by an authorized  
Volkswagen dealer or authorized Volkswagen Service Facility.  
Special considerations  
When it is very hot and humid outside, water condensation can drip from the air conditioner  
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.  
The climate control system adjusts the passenger compartment temperature as fast as possible  
considering the outside temperature.  
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is  
started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
