Monitor the 56 indicator lamp on the center console (୴ page 27) and the mul-
tifunction display in the instrument cluster (
୴ page 24) 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 77) has deactivated the air bag.
ț the message
Front passenger air bag activated see Oper.’s Man.
or the mes-
sage

should not ap-
pear 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 77), 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
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.
