A
CAUTION:
If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating air bag must be kept clear. Don't
put anything between an occupant and an air
bag, and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering and don't let seat covers block the
inflation path of a side impact air bag.
When should an air bag inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal or
near-frontal crashes. The frontal air bags are designed to
inflate only if the impact speed is above the system's
designed "threshold level." If your vehicle goes straight
into a wall that doesn't move or deform, the threshold
level is about 9 to 15 mph (14 to 24
km/h).
The
threshold level can vary, however, with specific vehicle
design, so that it can be somewhat above or below this
range. If your vehicle strikes something that will move
or deform, such as a parked car, the threshold level will
be higher. The driver's and right front passenger's
frontal air bags are not designed to inflate in rollovers,
side impacts, or rear impacts, because inflation would
not help the occupant.
The driver's and right front passenger's side impact air
bags are designed to inflate in moderate to severe side
crashes involving a front door. A side impact air bag
will inflate if the crash severity is above the system's
designed "threshold level." The threshold level can vary
with specific vehicle design. Side impact air bags are not
designed to inflate in frontal or near-frontal impacts,
rollovers or rear impacts, because inflation would not
help the occupant. A side impact air bag will only
deploy on the side of the vehicle that is struck.
