- Parking heater - heats the engine and 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.
The heater is fuel-driven and is fitted in the front right-hand wheel housing.
Battery and charging
The heater is powered by the car's starter battery. If the charge level of the starter battery is too low, then the heater is switched off automatically and the driver display shows a message.
Fuel and refuelling
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.
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.
