Anchor the top strap to this bracket. Once you have the
top strap anchored, you'll be ready to secure the child
restraint itself.
Securing a Child Restraint in the Center
Front Seat Position
Don't use child restraints in this position.
The restraints won't work properly.

1-43
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 right front passenger air bag. 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.

1-45
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
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.) 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.

1-47
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, 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.

1. Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
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.
Side Access Panel (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 on the panel to open it.
You must close the side access panel before you can
close the driver's door.

2-9
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.
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.

2-10 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.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.
If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.
Content Theft-Deterrent
(If Equipped)
Your vehicle may be equipped with a Content
Theft
-Deterrent alarm system.
With this system, the
SECURITY light will flash
as you open the door
(if your ignition is off).
This light reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.

2-11
3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.
If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go off. Your vehicle's
headlamps will flash and the horn will sound for
110 seconds, then will turn off to save the battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are locked.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any door with the
key. You can also turn off the alarm by pressing UNLOCK on
the remote keyless entry transmitter. The alarm won't stop if
you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
