Along with seat belts and pretensioners, Advanced Front
Airbags work with the knee bolsters to provide improved
protection for the driver and front passenger. Side airbags
also work with seat belts to improve occupant protection.
• The Occupant Classification Module (OCM) is lo-
cated 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 Con-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
• Your vehicle has four Weight Sensors located between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
• The Supplemental Side Airbag Inflatable Curtains
(SABIC) may deploy during collisions where the
impact is confined to a particular area of the side of the
vehicle, depending on the severity and type of colli-
sion. In these events, the ORC will deploy the SABIC
only on the impact side of the vehicle. Because airbag
sensors estimate deceleration over time, vehicle speed
and damage by themselves are not good indicators of
whether or not an airbag should have deployed.
A quantity of non-toxic gas is generated to inflate the
side curtain airbag. The inflating side curtain airbag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one quarter of the time it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the side curtain
