Air conditioner operation
Read and follow the introductory information and safety information first⇒
Introduction to the subject 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 not moving 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.
For manual AC
- Switch off air recirculation ⇒ Air recirculation .

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.

The air coming out of the vents flows through the passenger compartment and out through vents below the rear window. Do not cover these slots with clothing or other things.
