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.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
- frontal crash. The air bag will 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 8 to 11 mph
(13 to 18 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 air bag is not
designed to inflate in rollovers, side impacts or rear
impacts, because inflation would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near
- frontal impacts.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing system
detects that the vehicle is in a crash. The sensing system
triggers a release of gas from the inflator, which inflates the
air bag. The inflator, air bag and related hardware are all part
of the air bag modules inside the steering wheel and in the
instrument panel in front of the right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near - frontal collisions,
even belted occupants can contact the steering wheel or the
instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily because
an occupant’s motion is not toward those air bags. Air
bags should never be regarded as anything more than a
supplement to safety belts, and then only in moderate to
severe frontal or near
- frontal collisions.
