seatback.
J(Heated Seat and Seatback):Press to turn on the
heated seat and seatback.
The light on the button will come on to indicate that the
feature is working. Press the button to cycle through the
temperature settings of high, medium, and low and to turn
the heat to the seat off. Indicator lights will show the level
of heat selected: three for high, two for medium, and one

Head Restraints
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant’s head.
This position reduces the chance of a neck injury in a
crash.Pull the head restraint up
to raise it. To lower the
head restraint, press the
release button, located on
the top of the seatback,
while you push the head
restraint down.
The second row seats have head rests that can be
adjusted up and down.

Lap-Shoulder Belt
All seating positions in your vehicle have a lap-shoulder
belt except for the center front passenger position
(if equipped) if your vehicle is a crew or extended
cab, which has a lap belt. SeeLap Belt (Crew and
Extended Cab) on page 1-34for more information.
Here is how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the
belt go back slightly to unlock it. Then pull the belt
across you more slowly.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let
the belt go back all the way and start again.
Engaging the child restraint locking feature
may affect the passenger sensing system.
SeePassenger Sensing System on page 1-81.3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-35.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
See “Shoulder Belt Height Adjustment” later in
this section.
1-28

Shoulder Belt Height Adjuster
Your vehicle has a shoulder belt height adjuster for the
driver and right front passenger.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should
be away from your face and neck, but not falling off
your shoulder. Improper shoulder belt height adjustment
could reduce the effectiveness of the safety belt in a
crash.
To move the adjuster
down for the regular and
crew cabs, squeeze the
buttons (A) on the sides of
the height adjuster and
move the height adjuster
to the desired position.On the extended cabs,
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.

The manufacturer’s instructions that come with the
booster seat state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below t test:
Sit all the way back on the seat. Do the knees bend
at the seat edge? If yes, continue. If no, return to
the booster seat.
Buckle the lap-shoulder belt. Does the shoulder belt
rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See “Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt on page 1-28for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
Does the lap belt t low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
Can proper safety belt t be maintained for the
length of the trip? If yes, continue. If no, return
to the booster seat.
Q:What is the proper way to wear safety belts?
A:An older child should wear a lap-shoulder belt
and get the additional restraint a shoulder belt can
provide. The shoulder belt should not cross the face
or neck. The lap belt should t snugly below the hips,
just touching the top of the thighs. This applies belt
force to the child’s pelvic bones in a crash. It should
never be worn over the abdomen, which could cause
severe or even fatal internal injuries in a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-28.
According to accident statistics, children and infants
are safer when properly restrained in the rear seating
positions than in the front seating positions.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.

{CAUTION:
Children who are up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer protection for adults and older
children, but not for young children and
infants. Neither the vehicle’s safety belt system
nor its airbag system is designed for them.
Young children and infants need the protection
that a child restraint system can provide.
Q:What are the different types of add-on child
restraints?
A:Add-on child restraints, which are purchased by the
vehicle’s owner, are available in four basic types.
Selection of a particular restraint should take into
consideration not only the child’s weight, height,
and age but also whether or not the restraint will
be compatible with the motor vehicle in which it will
be used.
1-40

For most basic types of child restraints, there are
many different models available. When purchasing
a child restraint, be sure it is designed to be
used in a motor vehicle. If it is, the restraint will
have a label saying that it meets federal motor
vehicle safety standards.
The restraint manufacturer’s instructions that
come with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck. This is
necessary because a newborn infant’s neck is
weak and its head weighs so much compared
with the rest of its body. In a crash, an infant
in a rear-facing seat settles into the restraint,
so the crash forces can be distributed across
the strongest part of an infant’s body, the back
and shoulders. Infants should always be
secured in appropriate infant restraints.
{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children should always be secured in
appropriate child restraints.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, overhead console, front
sensors, rollover sensor module, or airbag wiring
can affect the operation of the airbag system.
