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 theft-deterrent alarm system.
A light located on top of your instrument panel (near the
center of the vehicle, next to the windshield) will ¯ash
slowly to let you know that the system has been armed.While armed, the doors will not unlock with the power
door lock switch.
Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition to ON. The
horn will sound and the parking lamps will ¯ash for up to
two minutes.
When the alarm is armed, the liftgate may be opened
with the remote keyless entry transmitter or with a key.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
door lock switch to lock the doors while any door or
the liftgate is open and the key is removed from
the ignition. If you would like to turn on power door lock
switch arming, see
Vehicle Personalization on
page 2-61.
When the security light ¯ashes quickly the system is
ready to arm with the power door lock switches.
Then the security light will stop ¯ashing and stay on
when you press the rear of the power door lock switch,
to let you know the system is arming. After all doors
and the liftgate are closed and locked, the security light
will begin ¯ashing at a very slow rate to let you know
the system is armed.
2-27

Arming with the Remote Keyless Entry
Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key
is not in the ignition. The security light will turn on to let
you know the system is arming. After all doors and
the liftgate are closed and locked, the security light will
begin ¯ashing at a very slow rate to let you know
the system is armed.
Arming with Your Key
Your alarm system will arm when you use your key to
lock the doors. The security light will turn on to let
you know the system is arming. After all doors and the
liftgate are closed and locked, the security light will
begin ¯ashing at a very slow rate to let you know the
system is armed. If you would like your key not to
arm the system, see
Vehicle Personalization on
page 2-61.
Arming Con®rmation
If remote unlock con®rmation is on, your parking lamps
will ¯ash brie¯y to let you know when your alarm
system has disarmed. If you would not like the parking
lamps to ¯ash, see
Vehicle Personalization on
page 2-61.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The security light will stop ¯ashing to let you know the
system is no longer armed.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the doors. The security light will stop
¯ashing to let you know the system is no longer armed.
If you would like your key not to disarm the alarm
system, see
Vehicle Personalization on page 2-61.

PASS-KeyžIII
Your PASS-KeyžIII 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 modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
žIII uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-KeyžIII Operation
Your vehicle is equipped
with the PASS-KeyžIII
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
žIII 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.
When the PASS-Key
žIII 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 the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
2-29

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 instrument panel PASS
KEY fuse. If the 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 or
a locksmith who can service the PASS-Key
žIII to
have a new key made. SeeFuses and Circuit Breakers
on page 5-96.
It is possible for the PASS-Key
žIII decoder to learn the
transponder value of a new or replacement key. Up
to 10 additional keys may be programmed for the
vehicle. This procedure is for learning additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith
who can service PASS-Key
žIII to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
žIII to get a new key blank that is cut exactly
as the ignition key that operates the system.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
žIII to
have new keys made. To program additional keys you
will need two current driver's keys (black in color).
You must add a step to the following procedure. After
Step 3 repeat Steps 1 through 3 with the second current
driver's key. Then continue with Step 4.To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the ignition key in the ignition and start the
engine. If the engine will not start see your dealer
for service.
3. After the engine has started, turn the key to OFF
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
žIII system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
žIII system at this time.
If you lose or damage a PASS-Key
žIII key, see your
dealer or a locksmith who can service PASS-KeyžIII to
have a new key made.

Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
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 HomeLink
žTransmitter.
Read the instructions completely before attempting to
program the HomeLink
žTransmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
žprogramming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
žbuttons should be erased
for security purposes. Refer to ªErasing HomeLinkž
Buttonsº or, for assistance, contact HomeLinkžon the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the 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
transmitter to the remaining two HomeLink
žbuttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
ž
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand 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 ªGate Operator and Canadian
Programmingº later in this section.
4. The indicator light will ¯ash slowly at ®rst and then
rapidly after HomeLink
žsuccessfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
