If your vehicle has a right front passenger’s side impact
air bag it is located in the side of the passenger’s
seatback closest to the door.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Do not put
anything between an occupant and an air bag,
and do not attach or put anything on the
steering wheel hub or on or near any other air
bag covering. Do not let seat covers block the
ination path of a side impact air bag.

What Will You See After an Air Bag
Inates?
After the air bag inates, it quickly deates, so quickly
that some people may not even realize the air bag
inated. Some components of the air bag module will
be hot for a short time. These components include the
steering wheel hub for the driver’s frontal air bag and the
instrument panel for the right front passenger’s frontal
air bag. For vehicles with side impact air bags, the side
of the seatback closest to the driver’s and/or right front
passenger’s door will be hot. The parts of the bag that
come into contact with you may be warm, but not too hot
to touch. There will be some smoke and dust coming from
the vents in the deated air bags. Air bag ination doesn’t
prevent the driver from seeing or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but can not get out of the vehicle after an
air bag inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inate (if battery power is available). You can lock
the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.
