Possible causes/consequences and M M Solutions
The classification of the person on the front-passenger seat is
incorrect.
Make sure the conditions for a correct classification of the per-
X
son on the front-passenger seat are met (
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the
X
front-passenger seat may not be used.
Have OCS checked as soon as possible at an authorized
X
Mercedes-Benz Center.
OCS is malfunctioning.
Make sure there is nothing between the seat cushion and the
X
child seat.
Make sure that the entire base of the child restraint system rests
X
on the seat cushion of the front-passenger seat. The backrest of
the forwards-facing child restraint system must, as far as pos-
sible, be resting on the backrest of front-passenger seat. If nec-
essary, adjust the position of the front-passenger seat.
Make sure that the seat cushion length is fully retracted.
X
When installing the child restraint system, make sure that the
X
seat belt is tight. Do not pull the seat belt tight with the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.
Check the installation of the child restraint system.
X
Make sure that the head restraint does not apply a load to the
child restraint system. If necessary, adjust the head restraint
accordingly.
Make sure that no objects are applying additional weight onto
X
the seat.
If the PASSENGER AIR BAG OFF indicator lamp remains off and/
X
or the PASSENGER AIR BAG ON indicator lamp lights up, do not
install a child restraint system on the front-passenger seat. It is
recommended that you install the restraint system on a suitable
rear seat.
Have OCS checked as soon as possible at an authorized
