Gasoline driven vehicles can use a parking heater with timer function.

The additional heater/parking heater are positioned inside the front fenders, in front of the front left wheel arch.

The heater consists of:

• the heater unit
• the combustion preheater module (CPM)
• the exhaust system
• the air intake
• the water pump.

The heater is connected to:

• the engine cooling system
• the vehicle fuel tank
• central electronic module (CEM).

Both versions have a fuel pump (FP) located on the right-hand side in front of the fuel tank.

Vehicles with the parking heater function use the turn signal lamp stalk to control the heater. The information appears in the driver information module (DIM).
