Heater*

Updated 19/03/2020

The heater has two subfunctions that help to heat the passenger compartment or engine in different situations.

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.

The heater is fuel-driven and is fitted inside the engine compartment.

Note

When the heater is running, smoke may be emitted from under the front part of the car 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.

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.

Note

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

Fuel and refuelling

P5-1507–Climate–Fuel cap heater warning — 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 incline, this may limit the 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 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.
