Automatic window fog detection
Automatic window fog detection checks whether the windows are fogged up and if necessary
automatically adjusts the air flow to the windshield and side windows or switches on the windshield
heating. If the fan or the air conditioner AC is turned off, automatic window fog detection cannot work
properly.
Residual heat mode
The residual engine heat can be used for a limited time to heat the passenger compartment when the
ignition is switched off.
x Switch off the ignition.
x Push the REST .button. The feature will appear in the Climatronic display.
x Press the REST .button again to switch the feature off early.
The feature is switched off if it is draining the battery too much, and it does off automatically after 30
minutes. The fan speed is reduced to save energy.
Applying driver settings to all climate zones
The driver-side settings for temperature, fan speed, and air distribution can be applied to all of the
other climate zones.
x Push the SYNC .button. The indicator light in the button lights up and the changes are applied to
all climate zones.
x Push the SYNC .button again to cancel the feature.
The synchronization feature is deactivated if individual settings are entered for one of the other

goes out.
Air conditioner does not work
The air conditioner may not switch on for one the following reasons:
x The engine is not running (or a hybrid vehicle is not ready to drive).
x The fan is turned off.
x The air conditioner fuse has blown.
x The ambient air temperature is colder than +38 °F (+3 °C).
x The air conditioner compressor has been temporarily switched off due to excessive engine coolant
temperature.
x 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 the vents and flow through the passenger compartment and out through the
vents below the rear window. Do not cover these slots with clothing or other objects.
