Supplemental front air bag system
The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box.
These systems are designed to meet optional
certification requirements under U.S. regulations.
They are also permitted in Canada. The optional
certification allows the front air bags to be de-
signed to inflate somewhat less forcefully than
previously.However, all of the information,
cautions and warnings in this manual still
apply and must be followed.
The supplemental front air bag system is de-
signed to inflate in higher severity frontal colli-
sions, although it may inflate if the forces in an-
other type of collision are similar to those of a
higher severity frontal impact. It may not inflate in
certain frontal collisions. Vehicle damage (or lack
of it) is not always an indication of proper supple-
mental front air bag system operation.
The supplemental air bag system has dual stage
inflators for both the driver and passenger air
bags. The system monitors information from the
crash zone sensor, the diagnosis sensor unit and
seat belt buckle sensors that detect if the seat
belts are fastened. Inflator operation is based on
the severity of a collision and whether the seat
belts are being used. Only one front air bag may
