Heater

The heater helps the engine and passenger compartment reach the correct temperature before and during driving.
The heater has two subfunctions:
  • Parking heater - heats the passenger compartment, if necessary, when the parking climate control's preconditioning is activated.
  • Additional heater - heats the passenger compartment and engine, if necessary, during driving.

Either a fuel-driven heater or an electric heater is used, depending on the market1.

The heater is fitted in the front right-hand wheel housing.

 Note

When the heater is running, smoke may be emitted from the right-hand front wheel housing and a low hum may be heard. This is perfectly normal2.

Battery and charging

The heater is powered by the car's hybrid battery. If the charge level of the hybrid battery is too low, then the heater is switched off automatically and the driver display shows a message.

 Note

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

Fuel and refuelling3

Warning label on fuel filler flap.

The heater uses fuel from the car's normal fuel tank.

If the car is parked on a steep hill, the front of the car should point downhill to ensure that there is a supply of fuel to the heater.

If the level in the fuel tank is too low then the heater is switched off automatically and the driver display shows a message.

 Note

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

 Warning

Fuel which spills out could be ignited. Switch off the fuel-driven heater before starting to refuel.

Check in the driver display that the heater is switched off. The heat symbol is shown when it is operating.
