2-9 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.
1. Use a coin (or a similar object) to pry open
the transmitter.

2-10
2. Once the transmitter is separated, use a pencil (or a
similar object) to remove the old battery. Do not use
a metal object.
3. 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 the instructions
that follow.
Resynchronization
Pressing the 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 fuel door 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 horn
will sound and the exterior lamps will flash once. The
system should now operate properly. See your dealer for
service if your transmitter still 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 and the temperature between
65F (18C) and 85F (29C). 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
The trunk lock release button
is located on the left side of
the instrument panel below
the lamp controls. To use this
feature, your vehicle must
be in PARK (P) or
NEUTRAL (N) and the
VALET lockout button must
be in the OFF position.
To open the trunk, press the trunk lock release
button upward.
You can also press the trunk release button on the
Remote Keyless Entry (RKE) transmitter to access the
trunk compartment.

The trunk storage system can be used to organize many
different items inside the trunk. The storage
compartment (A) is located on top of the spare tire
cover (B).To install the storage system:
1. Remove the mat from the floor of the trunk. Remove
the handle from the spare tire panel and store it with
the spare tire.

2-14 Trunk Lid Tie Down
CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can't see or smell CO. It
can cause unconsciousness and even death. If you
ever need to drive with your trunk lid open, then:

Make sure all windows, the rear seat
pass
-through and sunroof are closed.

Turn the fan on your heating and cooling
system to its highest speed, with the setting
on VENT. This forces fresh outside air into
your vehicle.

Open all air ducts on the instrument panel.
Don't use the Trunk Lid Tie Down if you are
towing a trailer, or if you are carrying a pet in the
trunk, because of the danger of CO.
This feature is used to secure the trunk lid if it will not
close completely, such as when carrying large packages
in the trunk.
1. Attach the end loop of the tie down to the retainer
located at the center of the trunk sill (see view B).
2. Attach the clip end of the tie down to the D
-ring on
the trunk lid (see view A).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end to release
and loosen the cord.

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.

Lock the glove box.

Lock all doors except the driver's.

Give the valet key to the valet. Then take the master
key with you.
Theft-Deterrent System
If the ignition is off and any
door is open, the
SECURITY light will flash,
reminding you to arm
the system.

yellowblue
2-16
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
system. The SECURITY light should come on and
stay on.
3. Close all the doors. The SECURITY light should go
off within approximately 30 seconds.
When the theft system activates, the horn will sound and
the lamps will flash for about 30 seconds when the door
or trunk is opened without the key or RKE system.
Remember, the theft
-deterrent system won't arm if you
lock the doors with a key or use the manual door lock. It
activates only if you use a power door lock with the
door open or the RKE system.
To avoid activating the alarm by accident:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the RKE
system. (Pressing the unlock button on the RKE
transmitter disables the theft
-deterrent system.)
Unlocking a door any other way will activate the
alarm when a door or the trunk is opened.If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the RKE system, or by
starting the car with a valid key.
Changes or modifications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
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 RKE
system and close the door. Wait 30 seconds until the
SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the RKE
transmitter or by starting the car with a valid key.

2-17
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 arm the
theft
-deterrent system when leaving your vehicle.
Valet Lock
This switch is located inside the glove box on the
left
-hand side. Pressing this switch to ON will disable
the use of the trunk, fuel door and garage door opener.
Pressing this switch to
OFF will make these
features reusable.
Locking the glove box with your key will also help to
secure your vehicle. Note that the RKE transmitter can't
open the trunk or fuel door if the valet lock switch is in
the ON position.
PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III 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.
PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If when trying to start the vehicle, the engine does not
start and the STARTING DISABLED REMOVE KEY
message is displayed in the Driver Information Center,
your key should be checked for damage. Turn the
ignition off and try again.If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see ªFuses and
Circuit Breakersº in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer or a locksmith who can service the
PASS
-Key III to have a new key made.
If you are ever driving and the SERVICE THEFT
SYSTEM message is displayed in the Driver
Information Center or the SECURITY light comes on
and stays on, you will be able to restart your engine if
you turn it off. Your vehicle is not protected by the
PASS
-Key
III system at this time. Your PASS-Key III
system is not working properly and must be serviced by
your dealer.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.
