Parking heater

The parking heater heats the passenger compartment as necessary before driving if the car's preconditioning is activated.

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

When this symbol illuminates in the driver display, the parking heater may be active1.


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.

Depending on factors such as battery level, passenger compartment temperature and ambient temperature, the heater has different running times, but never longer than 40 minutes.


Make sure there is enough fuel in the car's 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.


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.


If there is a smell of fuel, unusual amounts of smoke, black smoke, or unusual sounds coming from the parking heater2, switch off the heater and, if possible, pull out its fuse. Volvo recommends that an authorised Volvo workshop should be contacted for repair.
