Switch off seat heating when it is not needed
to help reduce unnecessary fuel consumption.
Tips and troubleshooting
Please read the introductory information and
heed the Warnings and Notice
126.
If the cooling system switches off automatically or
will not switch on
The air conditioner only works when the engine is
running and the outside temperature is above about
+38 °F (+3 °C).
The air conditioner compressor switches off auto-
matically when the engine is very warm.
— Switch on the fan.
— Check the fuse for the air conditioning system
→ page 231, Replacing fuses.
— If there is still cause for concern, have the air con-
ditioner checked by an authorized Volkswagen
dealer or authorized Volkswagen Service Facility.
If the heating system does not switch on or does
not work as expected
The heating and defrost features are most effective
when the engine is warm.
— If there is a cause for concern, have the system
checked by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
If the windows fog up
The windows can fog up if they are colder than the
outside temperature and the air is very humid. Cold
air absorbs less moisture than warm air, which is
why windows fog up frequently in cold weather.
— 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 and to
help prevent the windshield from fogging up.
— Do not cover the air vents in the rear of the lug-
gage compartment so that air can flow through
the passenger compartment from front to rear.
— Press the button to switch on the defog/
defrost feature → page 127, Overview of the cli-
mate controls.
Maximum heating output and defrosting perform-
ance are not possible until the engine has reached
operating temperature.

If the wrong temperature units are set
The inside and outside temperatures can be dis-
played in either Fahrenheit (F) or Celsius (C).
— Change the temperature units in the
menu in the Infotainment system → page 26, In-
fotainment system operation and displays.
If there is water under the vehicle
When it is very hot and humid outside, water con-
densation can drip from the air conditioner evapora-
tor and form a puddle under the vehicle. This is nor-
mal and does not indicate a leak.
