XC90 Twin Engine 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.

Note

When the heater is running1, 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 when extra heat is required if the parking climate control's preconditioning is activated.

It is then switched off automatically when the right temperature, the time of a set timer or the heater's maximum running time has been reached.

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 heater needs to be used1.

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

Warning

Do not use preconditioning1:

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 heater1, switch off the heater and, if possible, pull out its fuse. Volvo recommends that an authorised Volvo workshop should be contacted for repair.
