Parking heater
The parking heater is powered by the car's traction battery. It is used to heat the battery and for heating the passenger compartment during preconditioning.
Note
Make sure that the battery has sufficient charge when the parking heater is used. If the charge level in the battery is too low, the heater will switch off.
Auxiliary heater
The auxiliary heater is powered by the car's traction battery. It starts and is controlled automatically when heating is required while the car is being driven. It switches off automatically when the car is turned off.
Note
If you deactivate the auxiliary heater's automatic starting, it may impact comfort in the passenger compartment as the climate control system will then have no heat source during electrical operation.
