Parking heater
The parking heater is one of two subfunctions of the car's heater. The heater is fitted in the front right-hand wheel housing.

This symbol illuminates in the driver display1 when the parking heater is active.
Note
When the heater is running2, smoke may be emitted from the right-hand front wheel housing and a low hum may be heard. A ticking sound from the fuel pump may also be heard from the rear section of the car. This is perfectly normal.
The parking heater starts automatically if the parking climate's preconditioning is activated and the passenger compartment needs to be heated up.
It switches off automatically when a set timer time or the heater's maximum run time expires, or if the car is restarted.
The heater's maximum running time is 40 minutes.
Note
Make sure there is enough fuel in the car's normal fuel tank if the parking heater needs to be used2.
Make sure that there is enough charge in the hybrid battery if the parking heater needs to be used.
Warning
Do not use preconditioning2:
- In unventilated spaces indoors. Exhaust gases are emitted if the heater starts.
- In locations with combustible or flammable material nearby. Fuel, gas, long grass, sawdust, etc. may ignite.
- When there is a risk that the heater’s exhaust line may be blocked. For example, deep snow inside the front right-hand wheel housing can obstruct the heater’s ventilation.
Remember that the preconditioning can be started by a timer that has been set for a long time in advance.
