When Should an Airbag Inﬂate?

The driver’s and right front passenger’s frontal airbags

are designed to inﬂate in moderate to severe frontal or

near-frontal crashes. But they are designed to inﬂate

only if the impact exceeds a predetermined deployment

threshold. Deployment thresholds take into account a

variety of desired deployment and non-deployment

events and 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.

In addition, your vehicle has “dual-stage” frontal airbags,

which adjust the restraint according to crash severity.

Your vehicle is equipped with electronic frontal sensors

which help the sensing system distinguish between a

moderate frontal impact and a more severe frontal

impact. For moderate frontal impacts, these airbags

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 16 mph

(19 to 26 km/h), and the threshold level for a

full deployment is about 18 to 22 mph (29 to 35.4 km/h).

The threshold level can vary, however, with speciﬁc

vehicle design, so that it can be somewhat above

or below this range.

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.

Frontal airbags (driver and right front passenger) are not

intended to inﬂate during vehicle rollovers, rear impacts,

or in many side impacts.
