closed, the ignition is off and the Retained Accessory
Power (RAP) is inactive. One of the following modes
may be selected for each transmitter:

To verify the mode selected, remove the key from the
ignition and close all of the doors after you've exited the
vehicle. Press the lock button on the transmitter to be
veri®ed and con®rm the appropriate feedback.
Repeat with the unlock button.
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 toyour 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.
See your dealer to have additional transmitters matched
to your vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.

Rear Door Security Locks
Your vehicle is equipped
with rear door security
locks that prevent
passengers from opening
the rear doors of your
vehicle from the inside.
To use one of these locks, do the following:
1. Open the rear door you want to lock.
2. Move the lever located on the inside door edge, all
the way to the lock symbol.
3. Close the door.
4. Do the same thing to the other rear door lock.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use.
To open a rear door when the security lock is on, do the
following:
1. Unlock the door.
2. Open the door from the outside.If you don't cancel the security lock feature, adults or
older children who ride in the rear seat won't be able to
open the rear door from the inside. You should let
adults and older children know how these security locks
work, and how to cancel the locks.
To cancel the rear door lock, do the following:
1. Unlock and open the door from the outside.
2. Move the lever all the way to the unlock symbol.
3. Do the same for the other rear door.
The rear door locks will now work normally.
Lockout Protection
The power door locks will not work if the key is in the
ignition and a door is open. You can override this feature
by holding the driver's side power door lock switch for
more than three seconds.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from the inside. Then get out and
close the door. Or, press the lock button on the remote
keyless entry transmitter after shutting the doors.
If your vehicle has a theft-deterrent system, see
Content
Theft-Deterrent on page 2-18.
2-13

Trunk Security Override
The remote keyless entry transmitter will unlock the
trunk even if the trunk release lockout switch is in LOCK.
Emergency Trunk Release Handle
Notice:The emergency trunk release handle is not
designed to be used to tie down the trunk lid or
as an anchor point when securing items in the trunk.
Improper use of the emergency trunk release
handle could damage it.
There is a glow-in-the-dark emergency trunk release
handle located near the trunk latch. This handle will glow
following exposure to light. Pull the release handle up
to open the trunk from the inside.

Theft-Deterrent Systems
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.
Content Theft-Deterrent
Your vehicle may have a
content theft-deterrent
alarm system. With
this system, the
SECURITY light will ¯ash
as you open the door
(if your ignition is off).
This light reminds you to activate the content
theft-deterrent system when leaving your vehicle.
To activate the system, do the following:
1. Open the door.
2. Lock the door with the power door lock switch or
with 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 about 30 seconds. The alarm is not armed
until the SECURITY light goes off.If a door is opened without the key or remote keyless
entry transmitter, the alarm will go off. Your vehicle's
lamps will ¯ash and the horn will sound for 30 seconds.
The lamps and horn will then turn off to save
battery power.
Remember, the content 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 a 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
afterthe 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 the driver's
door with your key. You can also turn off the alarm
by pressing the unlock button on the remote keyless
entry transmitter. The alarm won't stop if you try
to unlock a door any other way.
2-18

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down 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 car, 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 lamps ¯ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see
Fuses and Circuit Breakers on page 5-86.
If the alarm does not sound or the vehicle's lamps do
not ¯ash, the vehicle should be serviced by an
authorized service center.
