exterior lamps will ¯ash twice when unlocking the vehicle
and ¯ash 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 ¯ash 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 ¯ash once and the horn chirps
when locking the vehicle.
The exterior lamps will not ¯ash if the manual parking
lamps are on.
If your vehicle is equipped with the DIC, you must
program this feature using it. See
Driver Information
Center (DIC) on page 3-45.

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.
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
veri®ed and con®rm the appropriate feedback.
Repeat with the unlock button.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go toyour dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
See your dealer to have additional transmitters matched
to your vehicle.
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.

Rear Door Security Locks
Your vehicle is equipped
with rear door security
locks that prevent
passengers from opening
the rear doors of your
vehicle from the inside.
To use one of these locks, do the following:
1. Open the rear door you want to lock.
2. Move the lever located on the inside door edge, all
the way to the lock symbol.
3. Close the door.

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
content theft-deterrent
alarm system. With
this system, the
SECURITY light will ¯ash
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.If a door is opened without the key or remote keyless
entry transmitter, the alarm will go off. Your vehicle's
lamps will ¯ash 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
afterthe 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 the driver's
door with your key. You can also turn off the alarm
by pressing the unlock button on the remote keyless
entry transmitter. The alarm won't stop if you try
to unlock a door any other way.
2-18

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 ¯ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see
Fuses and Circuit Breakers on page 5-86.
If the alarm does not sound or the vehicle's lamps do
not ¯ash, the vehicle should be serviced by an
authorized service center.
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.
2-19

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.
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.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
Fuses
and Circuit Breakers on page 5-86. 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 who can service the
PASS-Key
žIII to have a new key made.
It is possible for the PASS-KeyžIII 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 programming additional
keys only.
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. You must 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. Verify that the new key has PK3
žstamped on it.
2. Insert the current driver's 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.
2-20

4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. 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.
6. 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
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 to have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle doesn't need an elaborate
ªbreak-in.º But it will perform better in the long run
if you follow these guidelines:
·Don't drive at any one speed Ð fast or
slow Ð for the ®rst 500 miles (805 km). Don't
make full-throttle starts.
·Avoid making hard stops for the ®rst 200 miles
(322 km) or so. During this time your new
brake linings aren't yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
·Don't tow a trailer during break-in. See ªTowing
a Trailerº in the Index for more information.
