Programmable Automatic Door Locks
(If Equipped)
If your vehicle has power door locks, it will be equipped
with an auto lock/unlock feature which enables you to
program your vehicle's power door locks.
The following is a list of the available
programming options:

All doors lock/Only the driver's door unlocks:
Press the lock side of the power lock switch on the
door panel once and then the unlock side once. If
your vehicle is not equipped with remote keyless
entry, you may not be able to utilize this option.

All doors lock/All doors unlock: Press the lock
side of the power lock switch on the door panel
once, and then 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 the unlock side 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.
For more information, see your dealer.
If your vehicle has an automatic transmission it will be
programmed to have all the doors lock automatically
when the shift lever is moved out of PARK (P). All the
doors will unlock when the shift lever is moved back
into PARK (P).
On a manual transmission, all doors will lock when
the vehicle speed is greater than 15 mph (24 km/h).
The doors will unlock when the key is removed from
the ignition.
The following instructions detail how to program your
door locks. Choose one of the previous programming
options before entering the programming mode.

2-9
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 while you perform the next step.
2. Turn your 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 previous four programming
options 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 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 you are
leaving the program mode). If the lock/unlock
switches are not pressed while in the programming
mode, the auto lock/unlock setting will not
be modified.Rear Door Security Lock (If Equipped)
With this feature, you can lock the rear doors so they
may not be opened from the inside by passengers.
The security lock lever is
located on the inside edge
of each rear door.
To use the security locks, do
the following:
1. Open one of the rear doors.
2. Slide the lever up to the lock symbol to engage the
lock or, slide the lever down to the unlock symbol to
disengage the lock.
3. Close the door.
4. Repeat these steps on the opposite rear door..
If the security locks are engaged, the rear doors of your
vehicle cannot be opened form the inside. If you want to
open a rear door when a security lock is on, unlock the
door and open the door from the outside.

Lockout Prevention
This feature stops the power door locks from locking
when the keys are in the ignition and a door is open, to
protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and
the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the locks from inside. Then get out and
close the door.
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.
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,

2-11
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 or
resynchronization is necessary. See the instructions
that follow.

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

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.
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.

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.
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 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 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.
