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.
