Front passenger
airbag
activated
See Operator’s Manual
Front passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front
passenger seat is empty. Ob-
jects on the seat or forces act-
ing on the seat may make the
system sense supplemental
weight.
Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Switch off the ignition (
page 36).
Open the front passenger door.
Remove child and child restraint from front passenger seat and
properly secure the child in rear seat employing the child restraint
if necessary.
Remove any other items from on and around the front passenger
seat and make sure the storage pocket on the back of the front pas-
senger seat is empty.
Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged behind
or around the seat, head restraints pushing against roof etc.). The
system may recognize such forces as supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.
Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 36).

See Operator’s Manual
Monitor the 75 indicator lamp on the center console (
page 27) and
the multifunction display in the instrument cluster (
page 26) for the following:
With the seat unoccupied and the ignition turned on,
the 75 indicator lamp on the center console should illuminate and re-
main illuminated, indicating that the OCS (
page 81) has deactivated the front
passenger front air bag.
the message

or
the message
Front passenger airbag deactivated See Operator’s Manual
should not appear in the multifunction display at any time the seat is unoccu-
pied. 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. De-
pending on the front passenger classification sensed by the OCS (
page 81), 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
out even after performing the above correc-
tive steps, do not have any children 12 years
old and under and other small individuals
use the front passenger seat until the sys-
tem has been repaired.

Possible solution
Front passenger
airbag
deactivated
See Operator’s Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Switch off the ignition (
page 36).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (
page 41).
Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged under-
neath, behind or around the seat). Such forces may cause the sys-
tem to sense that an occupant of a lesser weight than actually
present is on the front passenger seat.
Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 36).
