The heater has two sub-functions:
- Parking heater - heats the passenger compartment as needed when the parking climate's preconditioning is activated.
- Auxiliary heater - heats the passenger compartment while driving.
The heater is a high-voltage coolant heater and is mounted in the front right-side wheel housing.
Battery and charging
The heater is powered by the vehicle's hybrid battery. If the charge level in the hybrid battery is too low, the heater will switch off automatically and a message will be displayed in the instrument panel.
Note
Make sure that the battery has sufficient charge if the heater must be used.
