Emergency Trunk Release Handle
Notice:Do not use the emergency trunk
release handle as a tie-down or anchor point
when securing items in the trunk as it
could damage the handle. The emergency
trunk release handle is only intended to aid a
person trapped in a latched trunk, enabling
them to open the trunk from the inside.There is a glow-in-the-dark emergency trunk
release handle located inside the trunk near the
latch. This handle will glow following exposure
to light. Pull the release handle to open the trunk
from the inside.
Rear Seat Pass-Through
Your vehicle has a small door in the rear seat.
This door allows you to access the trunk from
inside the vehicle.
The rear seat armrest must be down for the
pass-through door to open. To release the
pass-through door, move the release up with your
ngers. To close the door, raise it and push it
until it latches.

— (On):Press this side of the button to turn the
lockout feature on. When the lockout feature
is turned on, the trunk cannot be unlocked with
the keyless entry transmitter or the trunk release
button located near the headlamp switch on
the instrument panel.

the Universal Home Remote transmitter, if
equipped.
Locking the glove box with your key will also help
to secure your vehicle.
SeeRemote Keyless Entry (RKE) System
Operation on page 96andTrunk on page 106for
additional information.Content Theft-Deterrent
The security light is
located on the
instrument panel cluster.
If the ignition is off and any door is open, the
security light will ash, reminding you to arm the
system.
To arm the system:
1. Open the door.
2. Lock the door using the power door lock
switch with the door open or the Remote
Keyless Entry (RKE) transmitter. The security
light should come on and stay on.
3. Close all the doors. The security light should
go off within approximately 30 seconds.
If a door or the trunk is opened without a key or a
RKE transmitter, the horn will sound and the
lamps will ash for about 30 seconds.
113

The theft-deterrent system will not 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 transmitter.
To avoid activating the alarm by accident:
Lock the vehicle with the door key or the
manual door lock after the doors are closed.
Always unlock a door with a key or use the
RKE transmitter 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 transmitter system, or by starting the car
with a valid key.
Changes or modications 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 ash.
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.
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, seeFuses and Circuit
Breakers on page 452. 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.

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.
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.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications 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.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you insert or remove
the key from the ignition or transition the key from
RUN, ACCESSORY, or START from the off
position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security light
comes on when trying to start the vehicle, the
key may have a damaged transponder. Turn the
ignition off and try again.
115

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,
seeFuses and Circuit Breakers on page 452.Ifthe
engine still does not start with the other key, your
vehicle needs service. If your vehicle does start, the
rst key may be faulty. See your dealer/retailer who
can service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.
It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
See your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to get a new key blank that
is cut exactly as the ignition key that operates the
system.To program the new key:
1. Verify that the new key has a
1stamped
on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed
and turn it to the RUN position within
ve seconds of removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.

Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode
(LED) indicator light above the Universal Home
Remote buttons, follow the instructions below.
Do not use the Universal Home Remote with any
garage door opener that does not have the stop
and reverse feature. This includes any garage door
opener model manufactured before April 1, 1982. If
you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.
144

Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed
Universal Home Remote buttons should be erased
for security purposes. See “Erasing Universal
Home Remote Buttons” later in section.
When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or
gate operator you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming the Universal Home
Remote System
To program up to three devices:
1. Press and hold down the two outside
Universal Home Remote buttons, releasing
only when the Universal Home Remote
indicator light begins to ash, after
20 seconds. Do not hold down the buttons for
longer than 30 seconds and do not repeat
this step to program a second and/or
third hand-held transmitter to the remaining
two Universal Home Remote buttons.
2. Hold the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from
the Universal Home Remote buttons
while keeping the indicator light in view.
3. At the same time, press and hold both the
desired Universal Home Remote button and
the hand-held transmitter button. Do not
release the buttons until Step 4 has been
completed.
Some entry gates and garage door openers
may require you to substitute Step 3 with
the procedure noted in “Gate Operator and
Canadian Programming” later in this section.
