The Additional heater/Parking heater is located by the firewall on the right-hand side of the engine compartment. The heater consists of:

• the heater unit
• the combustion preheater module (CPM)
• the exhaust system with muffler
• the air intake.

The heater is connected to:

• the engine cooling system
• the fuel tank
• the Control area network (CAN).

The heater is checked by CAN signals. The parking heater also has a water pump. Both versions have a fuel pump (FP) located on the rear axle near the fuel tank for the vehicle.

The turn signal lamp stalk is used to control the heater. The information appears in the driver information module (DIM).
