Remember, the 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
button or the remote keyless entry transmitter.
To avoid activating the alarm by accident,
do the following:

Always unlock a door with a known key or use the
remote keyless entry transmitter. (Using a known
key or pressing the unlock button on the remote
keyless entry transmitter disables the theft
-deterrent
system.) Unlocking a door any other way, such
as using an unknown key, will activate the
alarm system.

The vehicle should be locked with the door key after
the doors are closed if you don't want to activate the
theft
-deterrent system.
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 remote keyless entry
transmitter or by starting the vehicle with a known key.
The alarm won't stop if you try to unlock a door any
other way.
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 remote
keyless entry transmitter and close the door. Wait
30 seconds until the SECURITY light goes off.
3. Reach in and unlock the door using the manual lock
lever and open the door. The horn will sound and the
headlamps will flash.
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 activate the
theft
-deterrent system when leaving your vehicle.

Valet Lockout Switch
The valet lockout switch is
located inside the glovebox.
Pushing the VALET lockout switch to ON will disable
the use of the power trunk, fuel door and garage door
openers. Pushing the switch to OFF again will make
these features reusable. Locking the glove box with the
key will also help to secure your vehicle.
The remote keyless entry transmitter cannot be used to
open the trunk or fuel door if the valet lockout switch is
in ON. Also, the valet key will not unlock the glovebox
or trunk.
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.

2-20
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.
If the engine 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.

2-21
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 require
two current driver's keys (black in color). 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:

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.

After the engine has started, turn the key to OFF, and
remove the key.

Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.
The SECURITY 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.

Repeat the 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.

stored in the underseat storage compartment as shown.
Convenience Net
The convenience net is located inside the back wall of
the trunk. Put small loads, like grocery bags, behind the
net. It can help keep them from falling over during sharp
turns or quick starts and stops.

trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.
