WARNING

If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.

Do not use seat accessories
that block the inflation path of a
seat-mounted side impact airbag.

Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path
of an inflating roof-rail airbag
will be blocked.

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 front outboard 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 the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.

Frontal airbags may inflate at
different crash speeds depending
on whether the vehicle hits an
object straight on or at an angle,
and whether the object is fixed
or moving, rigid or deformable,
narrow or wide.

Thresholds can also vary with
specific vehicle design.

Frontal airbags are not intended
to inflate during vehicle rollovers,
rear impacts, or many side impacts.

In addition, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The 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.
