Parking heater

Updated 14/02/2022

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 active.1

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.

The heater has different running times. depending on factors such as battery level, passenger compartment temperature, and ambient temperature. If the battery is fully charged, the charger is connected, and the timer is set in good time before departure, enhanced preconditioning can be activated automatically in a cold climate. Enhanced preconditioning may mean a running time of a maximum of 120 minutes. The running time without enhanced preconditioning is up to 30 minutes.3

Depending on factors such as fuel availability, battery level, passenger compartment temperature and ambient temperature, the heater has different running times, but never longer than 30 minutes.1

Note

Make sure there is enough fuel in the car's fuel tank if the parking heater needs to be used.2

Make sure that there is enough charge in the hybrid battery if the parking heater needs to be used.

Warning

Do not use preconditioning if the car is equipped with a fuel-driven heater*:

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.

Warning

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.
