Autonomous ventilation
Autonomous ventilation supplies fresh air to the passenger compartment when the engine is off, which can significantly reduce the temperature in the passenger compartment (e.g. if a parked car is heated by the sun).
Additional heater (heater)
Can be used both when the engine is off for pre-heating the vehicle, and while driving (e.g. when the engine warms up). The heater works in conjunction with a heater, air conditioner or Climatronic air conditioner. Additional (autonomous) the heater also preheats the engine. When fuel is burned from the fuel tank while the auxiliary (autonomous) heater heats up the coolant. The coolant heats the air that enters the interior of the car (if fan speed B or C is non-zero).
Carefully! Working additional (autonomous) the heater draws fuel from the fuel tank and independently controls the fuel level in the tank. If there is very little fuel left in the tank, the additional (autonomous) the heater is switched off. It must be ensured that the exhaust pipe of the additional (autonomous) the heater, located in the lower part of the vehicle, was not clogged and the flow of exhaust gases was not blocked. When operating an additional (auxiliary heater) the battery is discharging. After repeatedly turning on the autonomous heating and ventilation for a long time, it is necessary to drive several kilometers to charge the battery.
Note: When the optional (autonomous) heater fan B or C is only switched on when the coolant temperature reaches approx. 50°C. When the outside temperature is low, steam may form in the area of the engine compartment. This is normal and should not cause concern. For proper operation of the auxiliary heater and independent ventilation, it is necessary that the air intake in front of the windshield is not blocked by ice, snow or fallen leaves. To ensure that warm air can enter the passenger compartment after switching on the additional heater, leave the temperature, fan speed and vents open at the optimum setting for you. It is recommended to selector

The transmitter with battery is installed inside the remote control. The receiver is located in the cabin of the vehicle. With a fully charged battery, the range of the remote control reaches several hundred meters. In the presence of obstacles between the remote control and the vehicle, bad weather conditions and a discharged battery, the range of the remote control may be significantly reduced. To enable or disable the optional (autonomous) heater, hold the remote control vertically, antenna A up. The antenna must not be covered by fingers or palm. Confident remote on/off of the optional (autonomous) the heater is possible only if the distance from the remote control to the vehicle is at least 2 m. After pressing the button, the indicator in the key fob-remote shows the user confirmation / result of the action.
