When shouldan air bag inflate? The air bag is designed to inflate in moderate to severe frontal or near-frontal crashes. The air bag will inflate only if the impact speed is above the system's designed "threshold level." If your vehicle goesstraight into a wall that doesn't move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h). The threshold level can vary, however, with specific vehicle design, that so it canbe 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 inflationwould not help the occupant. . In any particular crash, no one cansay whether an air bag should have inflated simply becauseof the damage to a vehicle orbecause of what the repair costs were. Inflation isdetermined by the angleof the impact and the vehicle's deceleration. Vehicle damage is only one indication of this. The air bag system is designed to work properly under a wide rangeof conditions, including off-road usage. Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See "Off-Road Driving" in the Index for more tips off-road driving. on What makes an air bag inflate? In a frontal or near-frontal impact of sufficient severity, the air bag sensing system detects that the vehicle is suddenly stopping asa result of a crash. The sensing system triggers a chemical reaction of the sodium azide sealed in the inflator. The reaction produces nitrogen gas, which inflates the air bag. The inflator, air bag and related hardware areall part of the air bag module packed inside the steering wheel. How does an air bag restrain? In moderateto severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel. The air bag supplements the protection provided by safety belts. Air bags distribute the force of the impact more evenly over occupant's upper body, stopping the the occupant moregradually. 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 nottoward the air bag. Air bags should never be regarded as anything more than a supplement to safety belts, and then only in moderate to severefrontal or near-frontal collisions. 1-32

When
should an air
bag
inflate?
The air
bag is designed to
inflate in moderate to severe
frontal or near-frontal crashes. 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
9
to
16
mph
(14
to
26
km/h).
The threshold level
can vary, however, with specific
vehicle
design,
so
that
it
canbe 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
the vehicle’s deceleration. Vehicle damage is only one
indication of this.
The
air
bag
system
is
designed to work properly under a
wide
range of conditions, including off-road usage.
Observe
safe driving speeds, especially on rough terrain.
As
always, wear your safety belt. See “Off-Road
Driving” in the Index
for
more
tips
on off-road driving.
What makes an air
bag
inflate?
In a frontal
or near-frontal impact of sufficient severity,
the air bag sensing system detects that the
vehicle
is
suddenly stopping
as a result of a crash. The sensing
system triggers a chemical reaction
of
the sodium azide
sealed in the inflator. The reaction produces nitrogen
gas, which inflates the air
bag. The inflator, air
bag
and
related hardware
are all part
of
the air bag
module
packed inside the steering wheel.
How
does an air
bag
restrain?
In
moderateto severe frontal
or
near-frontal collisions,
even belted occupants can contact the steering wheel.
The
air
bag
supplements 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
moregradually. 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 the
air bag.
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.
