When Should an Airbag Inﬂate?

Frontal airbags are designed to inﬂate in moderate to

severe frontal or near-frontal crashes to help reduce the

potential for severe injuries mainly to the driver’s or

right front passenger’s head and chest. However, they

are only designed to inﬂate if the impact exceeds a

predetermined deployment threshold. Deployment

thresholds are used to predict how severe a crash is

likely to be in time for the airbags to inﬂate and

help restrain the occupants.

Whether your frontal airbags will or should deploy is not

based on how fast your vehicle is traveling. It depends

largely on what you hit, the direction of the impact,

and how quickly your vehicle slows down.

Frontal airbags may inﬂate at different crash speeds.

For example:

• If the vehicle hits a stationary object, the airbags

could inﬂate at a different crash speed than if the

vehicle hits a moving object.

• If the vehicle hits an object that deforms, the

airbags could inﬂate at a different crash speed than

if the vehicle hits an object that does not deform.

• If the vehicle hits a narrow object (like a pole), the

airbags could inﬂate at a different crash speed

than if the vehicle hits a wide object (like a wall).

• If the vehicle goes into an object at an angle, the

airbags could inﬂate at a different crash speed

than if the vehicle goes straight into the object.

Thresholds can also vary with speciﬁc vehicle design.

Frontal airbags are not intended to inﬂate during vehicle

rollovers, rear impacts, or in many side impacts.

In addition, your vehicle has dual-stage frontal airbags.

Dual-stage airbags adjust the restraint according to

crash severity. Your vehicle has electronic frontal

sensors, which help the sensing system distinguish

between a moderate frontal impact and a more severe

frontal impact. For moderate frontal impacts, dual-stage

airbags inﬂate at a level less than full deployment.

For more severe frontal impacts, full deployment occurs.

Your vehicle may or may not have roof-rail airbags.

See Airbag System on page 1-54. Roof-rail airbags are

intended to inﬂate in moderate to severe side crashes.

Roof-rail airbags will inﬂate if the crash severity is above

the system’s designed threshold level. The threshold

level can vary with speciﬁc vehicle design.

Roof-rail airbags are not intended to inﬂate in frontal

impacts, near-frontal impacts, rollovers, or rear impacts.

Both roof-rail airbags will deploy when either side of

the vehicle is struck.

In any particular crash, no one can say whether an

airbag should have inﬂated simply because of the

damage to a vehicle or because of what the repair costs

were. For frontal airbags, inﬂation is determined by

what the vehicle hits, the angle of the impact, and how

quickly the vehicle slows down. For roof-rail airbags,

deployment is determined by the location and severity of

the side impact.
