WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Possible causes/consequences and M M Solutions
The classification of the person on the front-passenger seat is incor-
rect.
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 forward-facing child restraint system must lie as flat as possi-
ble against the backrest of the front passenger seat. If necessary,
adjust the position of the front-passenger seat.
Make sure that the seat cushion length is fully retracted.

When installing the child restraint system, make sure that the
X
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.
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
accordingly.
Make sure that no objects are applying additional weight onto the
X
seat.
If the PASSENGER AIR BAG OFF indicator lamp remains off
X
and/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 child restraint system on a
suitable rear seat.
Have OCS checked as soon as possible at an authorized
