Safety Belts
Refer to the following sections for
important information on how to use
safety belts properly.
.Safety Belts on page 3‑12.

Properly on page 3‑13.
.Lap-Shoulder Belt on page 3‑14.

Passenger Sensing
System
The passenger sensing system,
if equipped, turns off the front
outboard passenger frontal airbag
under certain conditions. No other
airbag is affected by the passenger
sensing system.
If the vehicle has one of the
indicators pictured in the following
illustrations, then the vehicle has a
passenger sensing system for the
right front passenger position unless
there is an airbag off switch located
in the glove box.
If there is an airbag off switch, the
vehicle does not have a passenger
sensing system. SeeAirbag On-Off
Switch on page 3‑29 for more
information.
The passenger airbag status
indicator will be visible on the
overhead console when the vehicle
is started.

page 3‑32 for important information.
Mirror Adjustment
Using hood-mounted air deflectors
and add-on convex mirror
attachments could decrease mirror
performance.

safety belts makes such good
sense.
Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
safety belt?
A: You could be—whether you
are wearing a safety belt or not.
Your chance of being conscious
during and after a crash, so you
can unbuckle and get out, is
much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear safety
belts?
A: Airbags are supplemental
systems only; so they work with
safety belts —not instead of
them. Whether or not an airbag
is provided, all occupants still
have to buckle up to get the
most protection. Also, in nearly all states and in
all Canadian provinces, the law
requires wearing safety belts.
How to Wear Safety Belts
Properly
This section is only for people of
adult size.
There are special things to know
about safety belts and children. And
there are different rules for smaller
children and infants. If a child will
be riding in the vehicle, see
Older
Children on page 3‑39 orInfants
and Young Children on page 3‑41.
Follow those rules for everyone's
protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts. There are important things to know
about wearing a safety belt properly.
.Sit up straight and always keep
your feet on the floor in front
of you.
.Always use the correct buckle
for your seating position.

After you move the adjuster to
where you want it, try to move it
down, without squeezing the buttons
for the regular and crew cabs,
or without pushing the release
button for extended cabs, to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
belts during the early stages of a
moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. And, if your
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle's safety belt system. See
Replacing Safety Belt System Parts
after a Crash on page 3‑21.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they are
available through your dealer. The
guides may provide added safety
belt comfort for older children who
have outgrown booster seats and
for some adults. When installed and
properly adjusted, the comfort guide
positions the belt away from the
neck and head.
Here is how to install a comfort
guide to the shoulder belt:
1. Remove the guide from its
storage clip on the interior body.
2. Place the guide over the beltand insert the two edges of the
belt into the slots of the guide.

Replacing Safety Belt
System Parts after a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑18.
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front
passenger.
The vehicle may have the following
airbags:
.A seat‐mounted side impact
airbag for the driver.
.A seat‐mounted side impact
airbag for the right front
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the right
front passenger and the person
seated directly behind the right
front passenger.

3-22 Seats and Restraints
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 3‑25.
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.
{WARNING
Because airbags inflate with great
force and faster than the blink
of an eye, anyone who is up
against, or very close to any
airbag when it inflates can be
seriously injured or killed. Do not
sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
