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. But they are designed to inﬂate

only if the impact speed is above the system’s

designed “threshold level.”

In addition, your vehicle has “dual stage” frontal air bags,

which adjust the amount of restraint according to crash

severity. For moderate frontal impacts, these air bags

inﬂate at a level less than full deployment. For more

severe frontal impacts, full deployment occurs. If the front

of your vehicle goes straight into a wall that does not

move or deform, the threshold level for the reduced

deployment is about 12 to 18 mph (19 to 29 km/h), and

the threshold level for a full deployment is about 18 to

24 mph (29 to 38.5 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, rear

impacts, or in many side impacts because inﬂation

would not help the occupant.

Your vehicle may or may not have a driver’s side impact

air bag. See Air Bag Systems on page 1-48. A driver

’s side impact air bag is designed to inﬂate in moderate

to severe side crashes involving the driver’s 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. A

driver’s side impact air bag is not designed to inﬂate

in frontal or near-frontal impacts, rollovers 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. For frontal air bags, inﬂation is determined

by the angle of the impact and how quickly the

vehicle slows down in frontal and near-frontal impacts.

For side impact air bags, inﬂation is determined by

the location and severity of the impact.
