Auxiliary heater (auxiliary water heater)
General
NOTE: The auxiliary heater is not currently designed for engine preheating.
The auxiliary heater optionally available for all Cayenne models makes it possible to create a pleasant climate before the start of a trip in winter and to also defrost the windshield. The auxiliary heater is based on the principle of an auxiliary water heater and is connected to the cooling circuit of the combustion engine and passenger compartment heat exchanger.
Operation
NOTE: The heating function is not deactivated when the outside temperature threshold of 59° F. (15° C) is exceeded in auxiliary heating mode.
Depending on the version, the customer can switch on the auxiliary heater in different ways at outside temperatures below 59° F. (15° C):
- Radio remote control
- Operation of a button in the operating and air-conditioning unit (center console)
- Timer function in the instrument cluster Auxiliary heating mode is switched off when the engine is started (engine speed > 300 rpm) or at the latest after 30 minutes.

The auxiliary heater is switched off by pressing the Off button "B". The LED lights up red. The maximum range (approx. 500 m) of the hand-held transmitter depends on the charge state of the battery as well as on possible interference from buildings and the general surroundings.
