3233997 - E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING - Description (Sedan)
Description
The rear window heater element, door mirror demister coils and the windscreen heater element absorb a considerable amount of energy. They must therefore be turned off once they have been working for a certain period of time.The demisting of the heated rear windscreen and the rear view mirrors takes place with a timer, according to the following logic.The system is turned on with:
- the ignition in the ON position
- engagement signal coming from the special button, in the air conditioning/heater control panel (or from the "rapid demisting" function of the actual air conditioner).
The power supply is also cut off under the following conditions:
- ignition key in the OFF position;
- disengagement signal from the button (or from the "rapid demisting" function);
- after the initial 10 minutes of operation, if the battery voltage goes below 11.6 V (if the voltage goes back up above 13 V, then the supply is restored).
Description
- The LED in the button stays on whilst the heated rear windscreen is activated.
