Heated Windshield (HFS)

The heated front screen is available as an option on all heater versions. For the IHKA system the heated front screen shares the same control switch and LED as the heated rear window. The heated front screen operation is timed dependent on the outside temperature and controlled by the BC1.

When the programmed defrost mode is requested with a short push on the defrost switch, all heated screens are switched on automatically. The LED will switch on only when the engine is running.

Workshop Hint 

The Heated Rear Window Relay is attached to the back of the fusebox located near the A pillar.

This relay is integral with the fuse box and cannot be replaced separately.

Workshop Hint 

Neither Heated Window (Front or Rear) will operate unless the engine is running. If the engine is turned off while the Heating is active, Heating will be switched off.
