Security Feedback
This feature provides feedback to the driver when the
vehicle receives a command from the remote keyless
entry transmitter. Feedback is only provided if all doors
are closed, the ignition is off and the Retained
Accessory Power (RAP) is inactive. One of the
following modes may be selected for each transmitter:
Mode 1: No feedback when locking or
unlocking vehicle.
Mode 2: Parking lamps, back
-up lamps and the
DRL exterior lamps will flash twice when unlocking
the vehicle and flash once when locking the vehicle.
Mode 3: Horn chirps when all doors are unlocked
(second time the button is pressed) and when locking
the vehicle.
Mode 4: Parking lamps, back
-up lamps and the DRL
exterior lamps will flash twice each time the button with
the unlock symbol is pressed; the horn chirps when
all doors are unlocked. Parking lamps and the DRL
exterior lamps flash once and the horn chirps when
locking the vehicle.
Feedback will be provided according to the mode that
has been selected. The exterior lamps will not flash if
the manual parking lamps are on.To change to another mode, do the following:
1. Close all the doors and turn the ignition on. Keep all
doors closed throughout this procedure.
2. Press and hold LOCK on the driver's power door lock
switch throughout this procedure. All the doors will lock.
3. Press the trunk button on the transmitter. The
security feedback will remain in its current mode.
The horn will chirp as feedback.
4. Press the trunk button again. Each time the trunk
button is pressed, the security feedback will advance
to the next mode, and the horn will chirp.
5. Release the power door lock switch. The security
feedback will remain in the most current mode selected.
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.
To verify the mode selected, remove the key from the
ignition and close all of the doors after you've exited the
vehicle. Press the lock button on the transmitter to be
verified and confirm the appropriate feedback.
Repeat with the unlock button.
If your vehicle is equipped with the Driver Information
Center (DIC), you must program this feature through
the DIC. See ªDriver Information Centerº in the Index.

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.

To unlock the trunk from the outside, insert the master
key and turn it clockwise.
Remote Trunk Release and Trunk Lockout
The TRUNK PUSH OPEN
release button is on the
driver's door trim map
pocket. Push this button
to open the trunk.
The transaxle must be
in PARK (P) or
NEUTRAL (N) for the
remote trunk release
button to work.
To lock the trunk from inside your vehicle, insert the
master key and turn it clockwise to LOCK. The VALET
key will not work in this procedure.
Trunk Security Override
The remote keyless entry transmitter, will open the trunk
even if the trunk release lockout switch is in LOCK.

2-18 Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still 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.

Insert the master key into the trunk release button
and turn it to LOCK.

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.
Content Theft-Deterrent
(If Equipped)
Your vehicle may have
a content 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 content
theft
-deterrent system when leaving your vehicle.
To activate the system do the following:
1. Open the door.
2. Lock the door with the power door lock switch
or with the remote keyless entry transmitter. The
SECURITY light should come 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.

2-19
If a door is opened without the key or remote
keyless entry transmitter, the alarm will go off.
Your vehicle's lamps will flash and the horn will sound
for 30 seconds. The lamps and horn will then turn off
to save battery power.
Remember, the content 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 switch with a door open, or with the remote
keyless entry transmitter. You should also remember
that you can start your vehicle with the correct ignition
key if the alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any door
with your key. You can also turn off the alarm by
pressing the button with the unlock symbol on the
remote keyless entry transmitter. The alarm won't
stop if you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver's
window and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should, but the
vehicle's lamps flash, 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 alarm does not sound or the vehicle's lamps do not
flash, the vehicle should be serviced by an authorized
service center.

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.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.

2-21
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 who can service the PASS
-Key III to
have a new key made.
It is possible for the PASS
-Key III 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.
Canadian Owners: If you lose or damage your keys,
only a GM dealer can service PASS
-Key III to have
new keys made. To program additional keys you will
need two current driver's keys (black in color). You add
a step to the following procedure. After Step 2 repeat
Steps 1 and 2 with the second current driver's key.
Then continue with Step 3.To program the new key, do the following:
1. Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start, see your dealer for service.
2. After the engine has started, turn the key to OFF, and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
4. The SECURITY telltale light will turn off once the
key has been programmed. It may not be apparent
that the SECURITY light went on due to how
quickly the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to restart your engine
if you turn it off. Your PASS
-Key III system, however,
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by the PASS
-Key
III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer to have a new key made.
