236 SAFETY
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.
