The parking heater is one of two subfunctions of the vehicle's heater. The heater is mounted in the front right-side wheel housing.
The parking heater starts automatically if the parking climate's preconditioning is activated and the passenger compartment needs to be heated.
Depending on factors such as battery level, passenger compartment temperature and ambient temperature, the heater has different running times. If the battery is fully charged, the charging cable is plugged in and the timer is set well in advance of departure, increased preconditioning can be automatically activated in cold weather. Increased preconditioning may mean an idling time of up to 120 minutes. The running time without extended preconditioning is up to 30 minutes.
