System Self-Test - Mercedes-Benz C-Class Operator's Manual

A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
If you place a child in a forward-facing child
R
restraint on the front-passenger seat:
move the seat as far back as possible
-
use the proper child restraint
-
recommended for the age, size and
weight of the child
secure child restraint with the vehicle's
-
seat belt according to the child seat
manufacturer's instructions
For children larger than the typical 12-
R
month-old child, the front-passenger front
air bag may or may not be activated.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
is empty or occupied by the weight of a
R
typical child up to twelve months old,
seated in a child restraint system.
is occupied by a small individual, such as a
R
young teenager or a small adult.
is occupied by a child in a child restraint
R
system whose weight is greater than that
of a typical twelve month old child.
These are examples of when the OCS
deactivates the front-passenger front air bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
Occupant safety
If the SmartKey is removed from the ignition
lock or is in position 0, the PASSENGER AIR
BAG OFF indicator lamp does not light up.

WARNING
If the red 6 SRS warning lamp in the
instrument cluster and the 45
indicator lamp light up simultaneously, the
OCS is malfunctioning. The front passenger
front air bag will be deactivated in this case.
Have the system checked by qualified
technicians as soon as possible. Contact an
authorized Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
Sit with the seat belt properly fastened in a
R
position that is as upright as possible with
your back against the seat backrest.
When seated, a passenger should not
R
position him/herself in such a way as to
cause the passenger's weight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximate the passenger's weight
category.
Read and observe all warnings in this
R
chapter.
