airbag is turned off until the fault is cleared. If an object
is lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the PAD Indicator Light (If Equipped) and the Airbag
Warning Light. Once the lodged object is removed, the
fault will be automatically cleared after a short period of
time.

The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.

The Occupant Classification Module (OCM) (If
Equipped) is located beneath the front passenger seat.
The OCM classifies the occupant into categories based
on the measurements made by the seat weight sensors.
The OCM communicates with the Occupant Restraint
Controller (ORC). The ORC uses the occupant cat-
egory to determine whether the front passenger airbag
should be turned off. It also determines the rate of
airbag inflation during a collision.
