Possible solution
Monitor the 56 indicator lamp on the center console (୴ page 29) and the mul-
tifunction display in the instrument cluster (
୴ page 26) for the following:
With the seat unoccupied and the ignition turned on,
ț the 56 indicator lamp on the center console should illuminate and remain
illuminated, indicating that the OCS (
୴ page 71) has deactivated the air bag.
ț the message
Front passenger airbag enabled See Operator’s Manual
or the
message
Front passenger airbag disabled See Operator’s Manual
should not
appear in the multifunction display at any time the seat is unoccupied. Wait at last
60 seconds for the system to complete the necessary check cycles and to make
sure neither message appears in the multifunction display.
If above conditions are met, you can occupy the front passenger seat again. Depend-
ing on the front passenger classification sensed by the OCS (
୴ page 71), the
56 indicator 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 56 indicator lamp remains
illuminated with an adult occupant on the
front passenger seat even after performing
the above corrective steps, do not have any
passenger use the front passenger seat until
the system has been repaired.
