Rear Seat Passengers
It’s very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in the
rear seat are hurt more
often in crashes than those
who are wearing safety belts.
Rear passengers who aren’t safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
The positions next to the windows have
lap-shoulder belts.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields. A booster seat (F-G) is a child restraint designed to
improve the fit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a five-point harness.
A booster seat can also help a child to see out the
window.

What Will You See After an Air Bag
Inflates?
After the air bag inflates, it quickly deflates, SG quickly
that some people may not even realize the air bag
inflated. 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 deflated air bags. Air
bag inflation doesn’t prevent the driver from seeing or
being able
to steer the vehicle, nor does it stop
people from leaving the vehicle. hen an
E bag inflates, there __ dust in t..-
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 a door. If you experience breathing problems following an air bag deployment, you
should seek medical attention.
