The air-intake aperture for the auxiliary warm-air
heater is located on the inner side of the left

climate control system of your vehicle and has
an auxiliary heating function.
The auxiliary heating system heats the air in the
vehicle interior to the set temperature (prese-

the heat of the running engine. The auxiliary
heating is operated directly using the vehicle's
fuel. For this reason, the tank content must be at
