System Self-Test - Mercedes-Benz 2013 C-Class Coupe Operator's Manual

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 either empty or occupied by a person
R
with a weight up to that of a typical twelve-
month-old child seated in a standard child
restraint
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.
If the SmartKey has been removed from the
ignition lock or is in position 0, the
Occupant safety
45 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.

System self-test

The 45 indicator lamp lights up if you:
turn the SmartKey to position 1 or 2 in the
R
ignition lock
on vehicles with KEYLESS-GO, press the
R
Start/Stop button once or twice
When an adult is sitting correctly on the front-
passenger seat and is categorized by the OCS
system as an adult, the 45 indicator
lamp lights up and goes off again after
approximately six seconds.
If the passenger seat is not occupied and the
OCS system detects this, the 45
indicator lamp remains lit and does not go off.
