Picture shows pre-production model.
Details and Technology
An auxiliary heat exchanger is connected to the water circuit in parallel with the front end heat exchanger.
The heat exchanger is installed under the floor behind the B-pillar, on the left hand side of the vehicle. The
control panel, with controls for temperature and air volume, is situated in the instrument panel. The warm
air is routed upwards through the floor panel and enters the load compartment/passenger compartment
via a duct bolted to the wood floor. The auxiliary heat exchanger can only be switched on when the engine
is running.
Benefits and Arguments
• Improved comfort in cold weather
Better heating of the load compartment/passenger compartment when the engine is switched on.
Remarks

Heater Booster (XC2) or additional Warm Water Heating (XG3) or Front Auxiliary Heater (HDB). Not
available on 3500 Chassis Cab models.
