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.
1. Use the round end of the door key or a coin to
pry open the transmitter.
2. Once the transmitter is separated, use a pencil
(or similar object) to remove the old battery.
Do not use a metal object.

3. Replace the battery. Insert the new battery as the
instructions under the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Resynchronize the transmitter. See
ªResynchronizationº following.
Resynchronization
Pressing the remote keyless entry transmitter buttons
numerous times (approximately 250 times) out of
the vehicle's operating range may cause the transmitter
not to work. Replacing the battery and pressing the
transmitter buttons out of range will also cause the
transmitter not to work. If only the instant alarm button
works, the transmitter needs to be resynchronized to the
receiver. Do this by pressing and holding both the lock
and unlock buttons on the transmitter for about eight
seconds. You must be within range of the vehicle.
Once the transmitter has been resynchronized, the locks
will cycle from lock to unlock. See your dealer for
service if your transmitter doesn't work 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 AUTO or ECON and the temperature
between 65 F (18 C) and 85 F (29 C).
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 use this feature, your
vehicle must be in PARK (P)
or NEUTRAL (N) and the
VALET lockout switch must
be off.
Press the trunk release button, located on the left side of
the instrument panel, to open the trunk.
You can also press the trunk button on the remote
keyless entry transmitter to access the trunk
compartment. To disable the use of this feature, see
ªValet Lockout Switchº in the Index.

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 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.
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.

Move the trunk release lockout switch to ON.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

Leave only the valet key.

Take all other keys and the Remote Keyless Entry
transmitter with you.

Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will flash,
reminding you to activate
the system.
The light will also flash if the battery has been
disconnected and reconnected. To arm the system, do
the following:
1. Open the door.
2. Lock the door using the power door lock or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all the doors. The SECURITY light should go
off within about 30 seconds.
The horn will sound and the lamps will flash for about
30 seconds when the door or trunk is opened without the
key or the remote keyless entry transmitter. The horn
also sounds if the locks are damaged.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
button or the remote keyless entry transmitter.
To avoid activating the alarm by accident:

Always unlock a door with a known key or use the
remote keyless entry transmitter. (Using a known
key or pressing the unlock button on the remote
keyless entry transmitter disables the theft
-deterrent
system.) Unlocking a door any other way, such
as using an unknown key, will activate the
alarm system.

The vehicle should be locked with the door key after
the doors are closed if you don't want to activate the
theft
-deterrent system.
If you activate the alarm by accident, unlock any door
with your key. You can also turn off the alarm by using
the unlock button on the remote keyless entry
transmitter or by using a known key. The alarm won't
stop if you try to unlock a door any other way

2-17
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door.
Wait 30 seconds until the SECURITY light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, 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 fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
theft
-deterrent system when leaving your vehicle.
Valet Lockout Switch
The valet lockout switch is
located inside the glovebox.
Pushing the VALET lockout switch to ON will disable
the use of the power trunk, fuel door and garage door
openers. Pushing the switch to OFF again will make
these features reusable. Locking the glove box with the
key will also help to secure your vehicle.
The remote keyless entry transmitter cannot be used to
open the trunk or fuel door if the valet lockout switch is
in the ON position. Also, the valet key will not unlock
the glovebox or trunk.

Exterior Lighting Battery Saver
If the headlamp or manual parking lamp control
has been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is turned to
OFF. This protects draining the battery in case you have
accidentally left the headlamps or parking lamps on. If
you need to purposely leave the lamps on for more than
10 minutes with the ignition in OFF or ACCESSORY,
turn the manual control knob off and then back on.
To delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
If the headlamp switch is turned on after the ignition key
is moved to either OFF or ACCESSORY, the lamps will
not time out.
Interior Lamps
Instrument Panel
Intensity/Brightness Control
The displays automatically dim when it becomes dark
outside and your lights are on. The displays
automatically brighten when it becomes light outside.
Backlighting will only remain active as long as the
parking lamps are on and it is dark outside.
Courtesy Lamps
The courtesy lamps are located on the ceiling above the
rear seat. These lamps come on with the control lamp
knob or when any door is opened and it is dark outside.
Puddle lamps are located on the bottom of the front and
rear door trim.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
