Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met. And, if your
vehicle has roof-mounted rollover airbags, safety
belt pretensioners can help tighten the safety
belts in a side crash or a rollover event.
Pretensioners work only once. If they activate
in a crash, you will need to get new ones,
and probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 89.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your
dealer/retailer will order you an extender. When
you go in to order it, take the heaviest coat you will
wear, so the extender will be long enough for
you. To help avoid personal injury, do not
let someone else use it, and use it only for the
seat it is made to t. The extender has been
designed for adults. Never use it for securing child
seats. To wear it, attach it to the regular safety
belt. For more information, see the instruction
sheet that comes with the extender.

Airbag System
Your vehicle has a frontal airbag for the driver and
a frontal airbag for the right front passenger.
Your vehicle may also have roof-mounted side
impact airbags designed for either side impact or
rollover deployment. Roof-mounted side impact
airbags are available for the driver and the
passenger seated directly behind the driver and
for the right front passenger and the passenger
seated directly behind that passenger.
If your vehicle has roof-mounted side impact
airbags, the word AIRBAG will appear on
the airbag covering on the sidewall trim near the
driver’s and right front passenger’s window.
Even if you have no right front passenger seat in
your vehicle there is still an active frontal airbag
in the right side of the instrument panel. Do not
place cargo in front of this airbag.{CAUTION:
Be sure that cargo is not near an airbag.
In a crash, an in ating airbag might force
that object toward a person. This could
cause severe injury or even death.
Secure objects away from the area in
which an airbag would in ate. For more
information, seeWhere Are the Airbags?
on page 72andLoading Your Vehicle on
page 356.
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 in ating bag, all
airbags must in ate very quickly to do their job.

Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. 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. All airbags are designed
to work with safety belts but do not
replace them.
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to in ate in

CAUTION: (Continued)
rollover, rear crashes, or in many side
crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided in
the past.
Roof-mounted side impact airbags are
designed to in ate in moderate to severe
crashes where something hits the side of
your vehicle. They are not designed to
in ate in frontal or in rear crashes. If the
vehicle is equipped with rollover capable
airbags, it has been designed to deploy
the roof-mounted side impact airbags in
the event of a vehicle rollover. Everyone
in your vehicle should wear a safety belt
properly — whether or not there is an
airbag for that person.
