in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock
feature which enables you to program your vehicle's
power door locks.
Your vehicle left the factory programmed to lock all
doors when the vehicle is shifted out of PARK (P) and
the engine is running and then unlock all of the doors
when the vehicle is shifted into PARK (P). You can set
the automatic lock feature to lock the doors you choose
when the vehicle is shifted out of PARK (P) and unlock
the doors you choose when the vehicle is shifted into
PARK (P). You can also choose to have none of
the doors lock or unlock. The following instructions
detail how to program your door locks. Before you
enter the program mode, you will want to choose
one of the programming options following the
programming instructions.

2-8
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever all the way toward you
and hold it there while you perform the next step.
2. Turn the key to RUN and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic
door locks. Select one of the four programming
options listed above, and follow the instructions.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, the locks will
automatically lock and unlock to indicate that you
have left the program mode. If this occurs, repeat
the procedure beginning with Step 1.
You can exit the program mode any time by turning
the ignition to RUN (the locks will automatically
lock and unlock to indicate that you are leaving the
program mode). If the lock/unlock switches are not
pressed while in the programming mode, the current
auto lock/unlock setting will not be modified.The following is a list of available programming options:

All doors lock/Driver's door unlocks only: Press
the lock side of the power lock switch on the
door panel once and then the unlock side once.

All doors lock/All doors unlock: Press the lock
side of the power lock switch on the door panel once,
and then press the unlock side twice (this is the
factory setting).

All doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
once, and then press the unlock side of the switch
three times.

No doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
twice. This turns off the automatic lock feature.
See your dealer for more information.
Lockout Prevention
To protect you from locking your key in the vehicle,
this feature stops the power door lock from locking
the driver's door 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.

Child Security Locks
You will find a security lock lever on the inside edge of
each rear door. Your vehicle may be equipped with one
of the two labels shown.With this feature, you can lock the rear doors so they
can't be opened from the inside by passengers. To use
the security locks do the following:
1. Open one of the rear doors.
2. Move the lever up to engage the security lock.
Move the lever down to disengage the security lock.
3. Close the door.
4. Do the same thing to the other rear door.
The rear doors on 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.

Keyless Entry System
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.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the
interior lights will come on. Pressing UNLOCK again
within three seconds will cause the remaining doors to
unlock. The parking lamps will flash and the interior
lights will come on.

Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.
Remote Panic Alarm
When the button with the horn symbol on the keyless
entry transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting the vehicle.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.

Tailgate
Use the ignition/door key to unlock/lock the tailgate.
Open the tailgate by lifting up on its handle while
pulling the tailgate toward you.
To shut the tailgate, firmly push it upward until it latches.
After you put the tailgate back up, pull it back towards
you to be sure it is latched securely.
Tailgate Removal
The tailgate on your vehicle can be removed to allow for
different loading situations. Although the tailgate can be
removed without assistance, you may want someone to
assist you with the removal to avoid possible damage to
the vehicle.To remove the tailgate, do the following:
1. Raise the tailgate
slightly and release
both retaining cable
clips. To release the
retaining cable clips,
lift the cable so it points
straight out and push
the cable clip forward.
2. With the tailgate at a slight upward angle, pull back
on the tailgate at the right edge and then move the
tailgate to the right to release the left edge.
Reverse the above 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 ignition and transmission will be locked.
Also remember to lock the doors.
If the key is in the ignition, with any door open, and
you try to lock your doors with the power door locks,
the driver's door will not stay locked. This will help to
keep you from locking your keys in the vehicle.
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
Even if you park in a lot where someone will be
watching your vehicle, it's still 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.

2-25
Content Theft-Deterrent
Your vehicle is equipped with a Content Theft-Deterrent
alarm system.
With this system, the
SECURITY message will
flash as you open the door
(if your ignition is off).
This message 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
message should come on and stay on. If you're using
the remote keyless entry transmitter, the door does
not need to be open.
3. Close all doors. The SECURITY message should go
off after approximately 15 seconds. The alarm is not
armed until the SECURITY message 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 about
two minutes, 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 closed.

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 the system has
been armed.
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 or by
placing the key in the ignition and turning it to START.
