Solutions
The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son of a stature corre-
sponding to that of an
adult.
The classification of the person on the front-passenger seat is incor-
rect.
X
Make sure the conditions for a correct classification of the person
on the front-passenger seat are met (
Y
page 51).
X
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
X
Have OCS checked as soon as possible at a Mercedes-Benz Com-
mercial Van Center.
The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seat
is:
R
unoccupied
R
occupied with the
weight of a child up to
twelve months old in a
child restraint system
OCS is malfunctioning.
X
Make sure there is nothing between the seat cushion and the child
seat.
X
Make sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as flat as possible
against the backrest of the front-passenger seat. If necessary,
adjust the position of the front-passenger seat.
X
When installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger
seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
X
Check for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
X
Make sure that no objects are applying additional weight onto the
seat.
X
If the PASSENGER AIR BAG OFF indicator lamp remains off, do not
install a child restraint system on the front-passenger seat. It is
recommended that you install the child restraint system on a suit-
able rear seat.
X
Have OCS checked as soon as possible at a Mercedes-Benz Com-
mercial Van Center.

been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
