Possible solution
Monitor the 75 indicator lamp on the center console (୴ page 29) and
the multifunction display in the instrument cluster (
୴ page 26) for the following:
With the seat unoccupied and the ignition turned on,
ț the 75 indicator lamp on the center console should illuminate and
remain illuminated, indicating that the OCS (
୴ page 75) has deactivated the
front passenger front 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 least 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. De-
pending on the front passenger classification sensed by the OCS (
୴ page 75), the
75 indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the sys-
tem checked as soon as possible by an authorized Mercedes-Benz Center.
Warning! G
If the 75 indicator lamp
remains illuminated with an adult occupant
on the front passenger seat even after per-
forming the above corrective steps,
do not have any passenger use the front
passenger seat until the system has been
repaired.
