1-14 In Brief
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 3‑28 for more
information.
The passenger airbag status
indicator will be visible on the
overhead console when the vehicle
is started.

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 3‑38 orInfants
and Young Children on page 3‑40.
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.
.Wear the lap part of the belt low
and snug on the hips, just
touching the thighs. In a crash,
this applies force to the strong
pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your
abdomen. This could cause
serious or even fatal injuries.

3-16 Seats and Restraints
Extended Cab
On the extended cab, push down on
the release button (A) and move the
height adjuster to the desired
position.
You can move the adjuster up just
by pushing up on the shoulder belt
guide.
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 3‑20.
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.
