Visual and audible seat-belt warning

For the seat-belt warning, the signals of the 2 seat-belt buckle switches (driver's belt/front-passenger belt) are monitored separately.

If the seat occupancy detector detects that the passenger seat is occupied, the passenger belt must be inserted into the seat belt buckle. This switches off the seat-belt warning.

The following situations are taken into account in respect of the issuing of a seat-belt warning:

• Front seat belt not fastened and distance driven less than 200 m 
  • Driver's side only:

    If the distance driven is less than 200 m, only the seat-belt warning lamp lights up. The vehicle may for example be driven out of a garage without triggering an acoustic seat-belt warning.

  • Front seat belt not fastened and distance driven more than 200 m 

    The seat-belt warning lamps lights up. The acoustic seat-belt warning is activated for approximately 90 seconds.

    Once the seat belt has been fastened, the seat-belt warning lamp goes out. The acoustic seat-belt warning is deactivated.

    • Driver's side:
    • If the seat belt has not  been fastened by the end of the acoustic seat-belt warning, the seat-belt warning lamp will stay on.
    • Passenger side:

    If the seat belt has not  been fastened by the end of the acoustic seat-belt warning, the seat-belt warning lamp and the acoustic seat-belt warning are deactivated.

  • Unfastening the front seat belt when the vehicle is in motion 
    • Driver's side:

      The seat-belt warning lamps lights up immediately.

      After approx. 15 seconds an acoustic seat-belt warning is activated for approx. 90 seconds.

      Once the seat belt has been fastened, the seat-belt warning lamp goes out. The audible seat-belt warning is deactivated.

      If the seat belt has not  been fastened by the end of the acoustic seat-belt warning, the seat-belt warning lamp will stay on.

    • Passenger side:

    After approximately 15 seconds, the seat-belt warning lamp will light up and an audible seat-belt warning will be issued for approx. 90 seconds.

    Once the seat belt has been fastened, the seat-belt warning lamp goes out. The audible seat-belt warning is deactivated.

    If the seat belt has not  been fastened by the end of the acoustic seat-belt warning, the seat-belt warning lamp and the acoustic seat-belt warning are deactivated.

    NOTE: Deactivating the acoustic seat-belt warning

    The acoustic seat-belt warning can be deactivated using encoding.

    This does not affect a legally stipulated seat belt warning.
