This system has a range of about 3 feet (1 m) up to
30 feet (9 m). 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 to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

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.

If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
The driver's door will unlock when UNLOCK
is pressed.
If UNLOCK is pressed again within five seconds, all
doors will unlock. Pressing the UNLOCK button will
also illuminate the interior lamps. See ªIlluminated
Entryº in the Index.All doors will lock when LOCK is pressed.
The trunk will unlock when the trunk symbol is pressed
when the ignition is in OFF. The trunk symbol will also
work when the ignition is on, but only while the
transaxle is in PARK (P).
Instant Alarm
When the button with the horn symbol on the remote
keyless entry transmitter is pressed, the horn will sound
and the headlamps and taillamps will flash for up to one
minute. This can be turned off by pressing the instant
alarm button again or by turning the ignition on. If your
vehicle is equipped with the Universal Theft
-Deterrent
feature, you may also turn off the instant alarm by
unlocking the vehicle with a key.
Personal Choice Features
The following list of features that are available on your
vehicle can be programmed to each driver's preference
for each of the key transmitters.

Memory Door Locks: This feature programs your
door locks to automatically lock or unlock when
shifting in and out of PARK (P).

after five seconds.

Perimeter Lighting: When the UNLOCK button on
the key transmitter is pressed, the headlamps,
parking lamps, back
-up lamps and cornering lamps
will turn on.
For more detailed information and programming

vehicle receives a command from the remote keyless
entry transmitter. One of the following modes may be
selected for each transmitter:

Vehicles are delivered programmed in Mode 5. To
change to another mode:
1. Turn the ignition key to OFF.
2. Press and hold LOCK on the driver's power door
lock switch.
3. Press the trunk button on the transmitter. The
transmitter will remain in its current mode.
4. Press the trunk button again. Each time the trunk
button is pressed, the transmitter will advance to the
next mode.
5. Release the power door lock switch.
This procedure only changes the mode for the
transmitter used to change this setting. The procedure
will need to be repeated for the second transmitter.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 only four transmitters
matched to it.
See your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two 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.
For battery replacement, use one Duracell
battery, type
DL
-2032, or a similar type.To replace the battery:
1. Insert a coin into the notch near the key ring. Turn
the coin counterclockwise to separate the two halves
of the transmitter.
2. Once the transmitter is separated, use a pencil eraser
to remove the old battery. Do not use a metal object.
3. Remove and replace the battery. Replace it as the
instructions inside the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Test the operation of the transmitter with your
vehicle. If the transmitter does not work,
resynchronize the transmitter.
Resynchronization
After replacing the battery in your transmitter, or if only
the instant alarm works, the transmitter needs to be
resynchronized to the receiver. Do this by pressing and
holding both the LOCK and UNLOCK buttons at the
same time for about eight seconds. You must be within
range of the vehicle.
Once the transmitter has been resynchronized, the horn
will chirp and the exterior lamps will flash once. The
system should now operate properly.

Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock Release
To unlock the trunk from the outside, insert the door key
and turn it clockwise.
Remote Trunk Release
The TRUNK release button
is on the instrument panel
to the left of the steering
column. The transaxle
must be in PARK (P) or
NEUTRAL (N).
If the remote trunk release button does not open the
trunk, make sure the remote trunk release lockout switch
in the glove box is in the on position.

yellowblue
2-15 Remote Trunk Release Lockout
The trunk release lockout
switch in the glove box
must be on for the TRUNK
button to work. This feature
allows you to secure items
in the trunk when you must
leave the ignition key with
an attendant.
To secure the trunk, turn off the TRUNK RELEASE
switch, lock the glove box, then take the door key with
you. Now the trunk button to the left of the steering
column will not open the trunk.
Trunk Security Override
The remote keyless entry transmitter (if equipped), will
open the trunk even if the trunk release lockout switch
is OFF.
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.
With the ignition off and the driver's door open, 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
and transaxle. And 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.

yellowblue
2-16 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?

If possible, park in a busy, well lit area.

Put your valuables in a storage area, like your
trunk or glove box. Be sure to close and lock the
storage area.

Close all windows.

Turn off the TRUNK RELEASE lockout in the
glove box.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.
Universal Theft-Deterrent
(If Equipped)
If your vehicle has
this option, it has a
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 when leaving your vehicle.
Activating the system:
1. Open the door.
2. Lock the door with the power door lock switch while
the door is open, or with the remote keyless entry
transmitter. The SECURITY light should turn 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.
