passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.
.Young children who get into
unlocked vehicles may be
unable to get out. A child can

2-12 Seats and Restraints
The person keeps going until
stopped by something. In a real
vehicle, it could be the windshield...or the instrument panel...or the safety belts!
With safety belts, you slow down as
the vehicle does. You get more time
to stop. You stop over more
distance, and your strongest bones
take the forces. That is why safety
belts make such good sense.
Seats and Restraints 2-25
The vehicle may have the following
airbags:
.A seat-mounted side impact
airbag for the rear seat
passenger seated directly
behind the driver.
.A seat-mounted side impact
airbag for the rear seat
passenger seated directly
behind the right front passenger.
All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger. With seat-mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job.
Here are the most important things
to know about the airbag system:
{WARNING
You can be severely injured or
killed in a crash if you are not
wearing your safety belt
—even if
you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are your only
restraint. See When Should an
Airbag Inflate? on page 2‑28.
Wearing your safety belt during a
crash helps reduce your chance
of hitting things inside the vehicle
or being ejected from it. Airbags
are “supplemental restraints” to
the safety belts. Everyone in your
vehicle should wear a safety belt
properly —whether or not there is
an airbag for that person.
Seats and Restraints 2-27
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol. The
system checks the airbag electrical
system for malfunctions. The light
tells you if there is an electrical
problem. SeeAirbag Readiness
Light
on page 4‑16for more
information.
Where Are the Airbags?
The driver frontal airbag is in the
middle of the steering wheel.
The right front passenger frontal
airbag is in the instrument panel on
the passenger's side.
Driver Side shown, Passenger
Side similar
The seat-mounted side impact
airbags for the driver and right front
passenger are in the side of the
seatbacks closest to the door.
The roof-rail airbags for the driver,
right front passenger, and second
row outboard passengers are in the
ceiling above the side windows.
