What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates,
so quickly that some people may not even realize
the air bag inflated. Some components of the air bag
--
module the steering wheel hub for the driver's
air bag, or the instrument panel for the right front
--
passenger's bag will be hot for a short time.
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 vents in the
deflated air bags. Air bag inflation doesn't prevent
the driver from seeing or from being able to steer the
vehicle, nor does it stop people from leaving the vehicle.

CAUTION:
When an air bag inflates, 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't get out of the
vehicle after an air bag inflates, then get fresh air
by opening a window or door.

Air bags are designed to inflate only once. After they
inflate, you'll need some new parts for your air bag
system. If you don't get them, the air bag system
won't be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
