Front passenger
airbag disabled
See Oper. 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 315).

Have the front passenger vacate the seat and exit the vehicle.

Adjust the seat in a height position (
page 318).

Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged underneath, behind or
around the seat). Such forces may cause the system to sense that an oc-
cupant of a lesser weight than actually present is on the front passenger
seat.

Keep the seat unoccupied, close the front passenger door and switch on
the ignition (
page 315).
Monitor the 59indicator lamp right of the instrument cluster
(
page 53) and the multifunction display in the instrument cluster

Possible solution
Front passenger
airbag disabled
See Oper. Manual
With the seat unoccupied and the ignition switched on (
page 315),


the 59indicator lamp right of the instrument cluster should
illuminate and remain illuminated, indicating that the OCS (
page 50)
has deactivated the air bag.


the message “Front passenger airbag enabled See Oper. Manual” or the
message “Front passenger airbag disabled See Oper. 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 dis-
play.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS
(
page 50), the59indicator 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!

If the 59indicator lamp re-
mains 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 pas-
senger seat until the system has been re-
paired.
