The auxiliary heater and ventilation
system allows the vehicle interior to be
heated in winter and ventilated in
summer. Operation of the system
allows ice, condensation and a thin
covering of snow to be cleared from the
windscreen. The auxiliary heater is
supplied with fuel from the vehicle fuel
tank and can be operated when the
vehicle is stationary with the ignition
switched off. The auxiliary ventilation
system is supplied with power by the
12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions produced by the auxiliary heater are removed via an exhaust pipe fitted underneath
the vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.
