SAFETY 169
Occupant Classification System (OCS) —
Front Passenger Seat
The Occupant Classification System (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.
* It is possible for a child to be classified as an adult, allowing
a full-power Passenger Advanced Front Air Bag deployment.
Never allow children to ride in the front passenger seat and
never install a child restraint system, including a rear-facing
child restraint, in the front passenger seat.
The OCS determines the front passenger’s most probable
classification. The OCS estimates the seated weight on the
front passenger seat and where that weight is located. The
OCS communicates the classification status to the ORC.
The ORC uses the classification to determine whether the
Passenger Advanced Front Air Bag inflation rate should be
adjusted.

WARNING!
Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.
Children 12 years or younger should always ride
buckled up in the rear seat of a vehicle with a rear
seat.
