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.

1-17 Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see ªSeatsº in the Index)
so you can sit up straight.
3. 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.
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.

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
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

To turn off the right front passenger's air bag, insert
your ignition key into the switch, push in, and move the
switch to AIR BAG OFF.
The AIR BAG OFF light will come on to let you know
that the right front passenger's air bag is off. The right
front passenger's air bag will remain off until you turn it
back on again, and the AIR BAG OFF light will stay on
to remind you that the air bag is off.
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.

Lap-Shoulder Belt (Extended 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.

4. Buckle, position and release the safety belt as
described in ªRear Seat Passenger Positions
(Extended Cab)º earlier in this section. Make sure
that the shoulder belt crosses the shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out from
the guides. Slide the guide onto the storage clip.
Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. Neither
the distance traveled nor the age and size of the traveler
changes the need, for everyone, to use safety restraints.
In fact, the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Smaller Children and Babies
CAUTION:
Children who are 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
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.

1-43
CAUTION:
Smaller children and babies should always be
restrained in a child or infant restraint. The
instructions for the restraint will say whether it is
the right type and size for your child. A very
young child's hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child's abdomen. In a crash, the belt would apply
force right on the child's abdomen, which could
cause serious or fatal injuries. So, be sure that
any child small enough for one is always properly
restrained in a child or infant restraint.
Infants need complete support, including support for the
head and neck. This is necessary because an infant's
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear
-facing restraint settles into the restraint, so the crash
forces can be distributed across the strongest part of the
infant's body, the back and shoulders. A baby should be
secured in an appropriate infant restraint. This is so
important that many hospitals today won't release a
newborn infant to its parents unless there is an infant
restraint available for the baby's first trip in a
motor vehicle.

CAUTION: (Continued)
Secure the baby in an infant restraint. If you're
using the infant restraint in the right front
passenger's position, be sure to turn off the 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.
