When using a top strap-equipped child restraint in a rear
outboard seating position of a crew cab model, route the
top strap through the opening in the head restraint. Then,
attach it to the anchor point for that seating position.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself. Tighten the top strap
when and as the child restraint manufacturer's
instructions say.
Securing a Child Restraint in a Rear
Outside Seat Position (Crew Cab Models)
You'll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one. Be sure
to follow the instructions that came with the child
restraint. Secure the child in the child restraint when and
as the instructions say.
1. Put the restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

1-49
5. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint. If
you're using a forward
-facing child restraint, you may
find it helpful to use your knee to push down on the
child restraint as you tighten the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
Securing a Child Restraint in the Center
Front Seat Position (Regular Cab &
Extended Cab Models) and in the Center
Rear Seat Position (Crew Cab Models)
Don't use child restraints in these positions.
The restraints won't work properly.

1-50
Jump Seats (Extended Cab)
Don't use child restraints in these positions.
The restraints won't work properly.
Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a passenger air bag. If your vehicle is a
regular cab pickup or an extended cab pickup, there's a
switch on the instrument panel that you can use to turn
off the right front passenger's air bag when you want
to secure a rear
-facing child restraint at the right front
passenger's position. See ªAir Bag Off Switchº in
the Index for more on this, including important
safety information.

1-51
Unless your vehicle has the air bag off switch and the
passenger's air bag has been turned off, never put a
rear
-facing child restraint in the right front passenger's
seat. Here's why:
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. If your vehicle
is a crew cab, do not use a rear
-facing child
restraint in the right front passenger's position.
If your vehicle is a regular cab pickup or an
extended cab pickup, be sure to turn off the air
bag before using a rear
-facing child restraint in
the right front seat position.
If a forward-facing child restraint is suitable for
your child, always move the passenger seat as far
back as it will go.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat of a
crew cab.

1-52
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 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. See ªAir Bag Off
Switchº in the Index.
You'll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one. Be sure
to follow the instructions that came with the child
restraint. Secure the child in the child restraint when and
as the instructions say.
1. Your vehicle has a right front passenger's air bag.
If your vehicle is a regular cab pickup or an extended
cab pickup and you are using a rear
-facing child
restraint in this seat, make sure the air bag is turned
off. See ªAir Bag Off Switchº in the Index. On all
models, if your child restraint is forward
-facing,
always move the seat as far back as it will go before
securing it in this seat. See ªSeatsº in the Index.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

1-54
6. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint.
If you're using a forward
-facing child restraint, you
may find it helpful to use your knee to push down on
the child restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
If you were using a rear
-facing child restraint in a
regular cab model or extended cab model, turn on the
right front passenger's air bag when you remove the
rear
-facing child restraint from the vehicle unless the
person who will be sitting there is a member of a
passenger air bag risk group. See ªAir Bag Off Switchº
in the Index.
CAUTION:
If the right front passenger's air bag is turned off
for a person who isn't in a risk group identified
by the national government, that person won't
have the extra protection of an air bag. In a
crash, the air bag wouldn't be able to inflate and
help protect the person sitting there. Don't turn
off the passenger's air bag unless the person
sitting there is in a risk group. See ªAir Bag Off
Switchº in the Index for more on this, including
important safety information.

2-10 Rear Door Security Lock (If Equipped)
With this feature, you can
lock the rear doors so they
can't be opened from the
inside by passengers.
To use one of these locks:
1. Open one of the rear doors.
2. You will find a security lock lever located on the
inside edge of the door. Move the lever up to engage
the lock. Move the lever down to disengage the lock.
3. Close the door.
4. Do the same thing to the other rear door.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and open the door from the outside.
Lockout Prevention
This feature protects you from locking your key in
the vehicle when the key is in the ignition and a door
is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.
Remote Keyless Entry System
(If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.

2-13
To replace the battery in the keyless entry transmitter:
1. Insert a thin coin in the slot between the covers of
the transmitter housing near the key ring hole.
Remove the bottom by twisting the coin.
2. Remove and replace the battery with a three volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.

2-14
Third Door (Extended Cab)
(If Equipped)
Your vehicle may be equipped with a side access panel
for convenience in loading and unloading cargo.
To open the side access panel, first open the driver's
front door. Then, use the handle located on the front
edge of the door panel to open it.
You must close the side access panel before you can
close the driver's door.
Tailgate
You can open the tailgate by pulling up on the handle
while pulling the tailgate down.
When you put the tailgate back up, be sure it
latches securely.
Follow these steps if you want to remove the tailgate:
1. Raise the tailgate slightly.
2. Remove both retaining
cables. To remove each
cable, turn it so the end
faces the front. Then,
push forward so the
larger part of the hole is
over the bolt. Pull the
end over the bolt.

2-15
3. With the tailgate halfway down, pull the tailgate
toward you at the left side and then move the tailgate
to the left to release the right side.
Reverse the procedure to reinstall. Make sure the
tailgate is secure.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have an automatic transmission,
taking your key out also locks your transmission.
Also remember to lock the doors.
