Function

Actuation of the rear window heater switch is directly read in by the SAM control unit.

The SAM control module then supplies power to the heated rear window, for 10 min.

The integrated LED provides a status feedback message via the rear window heater switch.

Actuating the rear window heater switch again before expiration of the heating period deactivates the rear window heater.
