Supplemental front air bag system
The driver supplemental air bag is located in the
center of the steering wheel; the front passenger
supplemental air bag is mounted in the instru-
ment panel above the glove box. These systems
are designed to meet optional certification re-
quirements under U.S. regulations. They are also
permitted in Canada. The optional certification
allows front air bags to be designed to inflate
somewhat less forcefully than previously. How-
ever, all of the information, cautions and
warnings in this manual still apply and
must be followed. The front air bags are
designed to inflate in higher severity frontal
collisions, although they may inflate if the forces
in another type of collision are similar to those of
a higher severity frontal impact. They may not
inflate in certain frontal collisions. Vehicle dam-
age (or lack of it) is not always an indication of
proper supplemental air bag 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
inflate in a crash, depending on the crash sever-
ity and whether the front occupants are belted or
