See Operator’s
ManualThe passenger front air bag and the
passenger-side knee bag are
activated while driving even though a
child, small individual, or object below
the system’s weight threshold is on
the passenger seat, or the passenger
seat is empty. Objects on the seat or
forces acting on the seat may make
the system sense supplemental
weight.Stop the vehicle in a safe location as soon as possible and check the
passenger seat for the following:
Switch off the ignition (page 37).
Apply the parking brake (page 59).
Remove child and child restraint from passenger seat.
Make sure that no objects which are applying supplemental weight
onto the seat are present. The system may recognize such supple-
mental weight and sense that an occupant on the passenger seat is
of a greater weight than actually present.
Keep the seat unoccupied, close the passenger door and switch on
the ignition (
page 37).
Monitor the 75indicator lamp on the center console
(

any time the seat is unoccupied. Wait at least 60 seconds for the sys-
tem to complete the necessary check cycles and to make sure neither

If above conditions are met, you can occupy the passenger seat again.
Depending on the passenger classification sensed by the
OCS (
page 71), the 75indicator lamp will remain
illuminated or go out.
If above conditions are not met, the system is not working properly. Have
the system checked as soon as possible by an authorized Mercedes-Benz
Center.
Warning!G
If the 75indicator lamp
remains illuminated with an adult occupant
on the passenger seat even after performing
the above corrective steps, do not have any passenger use the passenger seat until the
