1-10 Rear Seat (Extended Cab)
Folding the Rear Seat
The extended cab's rear seat can be folded up to provide
more cargo space. To fold the seat:
1. Pull forward on
the release strap
located under the
rear seat cushion.
2. Fold the seat cushion upward until it latches with
the seatback.
3. Push and pull on the
seat to make sure the
seat is secure.
The extended cab's rear seat can also be folded open for
more seating space. To use the seat:
1. Push rearward on the seat cushion while pulling up
on the release strap under the seat cushion. Pull the
seat cushion downward until it latches.
2. After pulling the seat cushion down, pull up on it to
make sure it is locked.

1-12
To return the seat to the passenger position, lift the floor
load panels and latch them into the seatback. Lift the
seatback up and push rearward all the way. Then lower
the seat cushion until it latches into position.
Pull forward on the seatback and up on the seat cushion
to make sure the seat is securely in place.
Check to see that the buckles on the driver's side
seatback are accessible to the outboard and center
occupant and are not under the seat cushions.
Safety Belts: They're for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
And it explains the air bag system.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers' belts
are fastened properly too.

1-19
4. 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 isn't long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you'd be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should
go over the shoulder and across the chest. These parts
of the body are best able to take belt restraining forces.
The safety belt locks if there's a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.

1-26
CAUTION:
Air bags inflate with great force, faster than the
blink of an eye. If you're too close to an inflating
air bag, as you would be if you were leaning
forward, it could seriously injure you. Safety belts
help keep you in position before and during a
crash. Always wear your safety belt, even with air
bags. The driver should sit as far back as possible
while still maintaining control of the vehicle.
CAUTION:
Anyone who is up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. Air bags plus lap
-shoulder belts offer
the best protection for adults, but not for young

CAUTION: (Continued)
children and infants. Neither the vehicle's safety
belt system nor its air bag system is designed
for them. Young children and infants need the
protection that a child restraint system can
provide. Always secure children properly in your
vehicle. To read how, see the part of this manual
called ªChildren.º
There is an air bag
readiness light on
the instrument panel,
which shows the
air bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

1-33
CAUTION:
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger's air bag could inflate
even though the switch is off.
If your vehicle is a regular cab pickup and
this ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in your
vehicle) until you have your vehicle serviced.
If your vehicle is an extended cab pickup and
this ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in the right
front passenger's seat) until you have your
vehicle serviced.
To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in, and
move the switch to the ON position.

1-37
Lap-Shoulder Belt (Extended Cab and Crew Cab)
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted. The 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.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

1-43
CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby doesn't weigh
much
-- until a crash. During a crash a baby
will become so heavy it is not possible to hold it.
CAUTION: (Continued)
CAUTION: (Continued)
For example, in a crash at only 25 mph (40 km/h),
a 12
-lb. (5.5 kg) baby will suddenly become a
240
-lb. (110 kg) force on a person's arms. A baby
should be secured in an appropriate restraint.

1-45
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 always should
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 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's unprotected by any
bony structure. This alone could cause serious or
fatal injuries. Young children always should be
secured in appropriate child restraints.

1-48
Q:How do child restraints work?
A:A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built
-in child restraint system is a
permanent part of the motor vehicle. An add
-on
child restraint system is a portable one, which is
purchased by the vehicle's owner.
For many years, add
-on child restraints have
used the adult belt system in the vehicle. To help
reduce the chance of injury, the child also has to
be secured within the restraint. The vehicle's belt
system secures the add
-on child restraint in the
vehicle, and the add
-on child restraint's harness
system holds the child in place within the restraint.
One system, the three
-point harness, has straps
that come down over each of the infant's shoulders
and buckle together at the crotch. The five
-point
harness system has two shoulder straps, two hip
straps and a crotch strap. A shield may take the
place of hip straps. A T
-shaped shield has shoulder straps that are
attached to a flat pad which rests low against the
child's body. A shelf
- or armrest-type shield has
straps that are attached to a wide, shelf
-like shield
that swings up or to the side.
When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is,
it will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system in
your vehicle, but the child also has to be secured within
the restraint to help reduce the chance of personal injury.
When securing an add
-on child restraint, refer to the
instructions that come with the restraint which may be
on the restraint itself or in a booklet, or both, and to this
manual. The child restraint instructions are important, so
if they are not available, obtain a replacement copy from
the manufacturer.

1-49 Where to Put the Restraint
(Regular Cab Pickup)
The child restraint must be secured properly in the right
front passenger seat. If you want to secure a rear
-facing
child restraint in the right front passenger's seat, turn off
the passenger's air bag. See ªAir Bag Off Switchº and
ªSecuring a Child Restraint in the Right Front Seat
Positionº in the Index for more on this, including
important safety information.
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Be sure to turn
off the air bag before using a rear
-facing child
restraint in the right front seat position.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle
-- even when no child is in it.
Where to Put the Restraint
(Extended Cab Pickup)
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in the rear seat, including an infant
riding in a rear
-facing infant seat, a child riding in a
forward
-facing child seat and an older child riding in a
booster seat. There is limited space in the rear seating
area of an extended cab model. If you want to secure a
child restraint in a rear seating position of an extended
cab model, especially in the rear center position, be sure
to study the instructions that came with your child
restraint to see if there is enough room to secure your
seat properly.
If a forward
-facing child seat must be secured in the
vehicle's right front seat, the seat should be moved back
as far as possible. However, it is better to secure the
restraint in a rear seat.
If you want to secure a rear
-facing child restraint in the
right front passenger's seat, turn off the passenger's air
bag. See ªAir Bag Off Switchº and ªSecuring a Child
Restraint in the Right Front Seat Positionº in the Index
for more on this, including important safety information.
