2005 MERCEDES-BENZ C CLASS COUPE reset

74 Safety and SecurityOccupant safetyWhen the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 56 indicator lamp will illuminate
for approximately six seconds when the en-
gine is started and then, depending on occu-
pant weight sensor readings from the seat,
remain illuminated or go out. With the
56 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 56 indicator lamp out, the
front passenger front air bag is activated.
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
56 indicator lamp will illuminate for
approximately six seconds when the engine
is started and then go out, indicating that
the front passenger front air bag is activat-
ed.
If the 56 indicator lamp is
illuminated, the front passenger front air
bag is deactivated and will not be deployed.
If the 56 indicator lamp is not illumi-
nated, the front passenger front air bag is
activated and will be deployed:

in the event of certain frontal impacts


if impact exceeds a preset deployment
threshold


independently of the side impact air
bags.
If the front passenger front air bag is
deployed, the rate of inflation will be
influenced by:


the rate of relevant vehicle deceleration
as assessed by the air bag control unit


front passenger's weight category as
identified by the Occupant Classification
System (OCS).
Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer's instruc-
tions.
