Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
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 indica-
tors 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 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 activate or deactivate the Passenger Ad-
vanced Front Air Bag depending on the occu-
pant’s seated weight. It is designed to deac-
tivate the Passenger Advanced Front Air Bag
for an unoccupied seat and for occupants
whose seated weight classifies them in a
category other than a properly seated adult.
This could be a child, teenager, or even an
adult.
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
• Passenger Air Bag Disabled (PAD) Indicator
Light – an amber light located on the over-
head sports bar
• Air Bag Warning Light
• Passenger Seat Belt
Occupant Classification Module (OCM)
And Sensor
The Occupant Classification Module (OCM)
is located underneath the front passenger
seat. The Sensor is located beneath the pas-
senger 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 classifica-
tion. The OCM communicates this informa-
tion to the ORC. The ORC uses the classifi-
cation to determine whether it should
activate or deactivate the Passenger Ad-
vanced Front Air Bag.
