SAFETY 345
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indicators
of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air bags
inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate
while helping to restrain the driver and front
passenger.
Occupant Classification System (OCS) —
Front Passenger Seat
The OCS is part of a Federally regulated safety
system for this vehicle. It is designed to provide
Passenger Advanced Front Air Bag output
appropriate to the occupant’s seated weight, as
determined by the OCS.
The Occupant Classification System (OCS)
consists of the following:

Occupant Restraint Controller (ORC)

Occupant Classification Module (OCM) and
Sensor located in the front passenger seat

Air Bag Warning Light
Occupant Classification Module (OCM) And
Sensor
The Occupant Classification Module (OCM) is
located underneath the front passenger seat.
The Sensor is located beneath the passenger
seat cushion foam. Any weight on the seat will
be sensed by the Sensor. The OCM uses input
from the Sensor to determine the front
passenger’s most probable classification. The
OCM communicates this information to the
ORC. The ORC may reduce the inflation rate of
the Passenger Advanced Front Air Bag
deployment based on occupant classification.
In order for the OCS to operate as designed, it is
important for the front passenger to be seated
properly and properly wearing the seat belt.
The OCS will NOT prevent deployment of the
Passenger Advanced Front Air Bag. The OCS
may reduce the inflation rate of the Passenger
Advanced Front Air Bag if the OCS estimates
that:

The front passenger seat is unoccupied or
has very light objects on it; or

The front passenger seat is occupied by a
small passenger, including a child; or

The front passenger seat is occupied by a
rear-facing child restraint; or

The front passenger is not properly seated or
his or her weight is taken off of the seat for a
period of time.
