Additional heater (autonomous heating and ventilation) (Skoda Octavia 5E)

Operating conditions of the additional heater (autonomous heating and ventilation, hereinafter briefly: autonomous heater): the battery charge is sufficient, there is enough fuel in the fuel tank (counter. pictogram In the instrument cluster display is not lit).

Autonomous ventilation

Autonomous ventilation supplies fresh air to the car interior when the engine is off, which allows to significantly reduce the temperature in the interior (for example, if a parked car is heated by the sun).

Additional heater (autonomous heater)

Can be used both with the engine off for preliminary heating of the car and while driving (for example, when warming up the engine). The heater works in conjunction with the heater, air conditioner or Climatronic climate control system. Additional (autonomous) the heater also preheats the engine. When the fuel from the fuel tank is burned during operation of the additional (autonomous) the heater heats up the coolant. The coolant heats the air that enters the car's interior (if the rotation speed of fan B or C is different from zero).

Caution! Additional working (autonomous) the heater takes fuel from the fuel tank and independently controls the fuel level in the tank. If there is very little fuel left in the tank, an additional (autonomous) the heater is switched off. It is necessary to ensure that the exhaust pipe of the additional (autonomous) heater, located at the bottom of the car, was not clogged and the flow of exhaust gases was not blocked. When the additional (autonomous heater) the battery is discharged. After repeated switching on of the autonomous heating and ventilation for a long time, it is necessary to drive several kilometers to charge the battery.

Note: When working additionally (autonomous) heater fan B or C only switches on when the coolant temperature reaches about 50°C. At low outside temperatures, steam may form in the engine compartment. This is normal and should not cause concern. For the independent heater and independent ventilation to function properly, the air intake in front of the windshield must not be 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 optimal temperature setting, fan speed and open deflectors. It is recommended to select the air flow direction or .

The transmitter with the battery is installed inside the remote control. The receiver is located inside the car. When the battery is fully charged, the range of the remote control reaches several hundred meters. If there are obstacles between the remote control and the car, bad weather conditions and a discharged battery, the range of the remote control may be significantly reduced. To turn on or off the additional (autonomous) heater, hold the remote control vertically with antenna A facing up. The antenna should not be covered by your fingers or palm. Confident remote switching on/off of additional (autonomous) heater is only possible if the distance from the remote control to the car is at least 2 m. After pressing the button, the indicator in the key fob shows the user confirmation/result of the action.
