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
climate zones using the Climatronic control unit. In this case, the indicator light in the SYNC .button
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.
.WARNING
High voltage systems in the engine compartment can cause electrical shocks or even
electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially CAReful when using jumper
cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or
being started:
– Never touch ignition cables. Never touch other components of the high-voltage
electronic ignition system.
– Never touch the wiring of the HID - High Intensity Discharge (Xenon) headlights.
.WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can
cause serious personal injury. Always remember that the radiator fan is temperature-
controlled and can come on suddenly even when the engine has been switched off for a while
and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks
from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the
high-voltage ignition system. Always use extreme CARe.
– Always make sure that jewelry, loose clothing and long hair do not get caught in
rotating engine parts. Before starting any work remove your jewelry, take off your necktie,
tie back and cover your hair, and do not wear clothing that can hang down and get caught
in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a
check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools.
Objects left behind can cause malfunctions, engine damage, and even fires.
.WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing
burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids
can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when
you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the
ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
