Volkswagen Touran Owners Manual: Operation

First read and observe the introductory information and safety warnings 

The auxiliary heater exhaust system, located under the vehicle, must not be blocked by snow, mud or other items. The exhaust fumes must not be obstructed in any way. The emissions generated by the auxiliary heater are removed via an exhaust pipe fitted underneath the vehicle.

When the vehicle interior is being heated, the warm air is first directed towards the windscreen and then via the air vents to the vehicle interior. This is dependent on the ambient temperature. You can determine the flow of the air by adjusting the position of the vents, for example to face the side windows.

The temperature at which the auxiliary heater heats the vehicle interior could be higher if the temperature control of the heating and fresh air system or air conditioning system was set to the highest setting before the auxiliary heater was switched on. This depends also on the ambient temperature.

When is the auxiliary heater not switched on?

• The auxiliary heater requires approximately the same amount of electricity as the dipped beam headlights. If the charge level of the vehicle battery is low, the auxiliary heater will switch off automatically or cannot be switched on. This will prevent problems with starting the engine.

• Activation is for one heating period only. The preset time has to be activated for every start.

Operating noises can be heard if the auxiliary heater is switched on.

At high levels of humidity in the outside air, but at low temperatures, condensation from the heating and fresh air system may evaporate through the active auxiliary heater. If this is the case, steam may appear underneath the vehicle. The vehicle is not damaged.

The vehicle battery will discharge if the auxiliary heater runs several times in an extended period. Drive the vehicle for an appropriate distance in order to recharge the vehicle battery. As a rule of thumb, drive the vehicle for the length of time you ran the system.
