Central Door Unlocking System
Your vehicle has a central door unlocking mode and a
theft
-deterrent system. When unlocking the driver's
door, you can unlock the other doors by holding the key
in the turned position for a few seconds or by quickly
turning the door key twice in the lock cylinder.
Power Door Locks
Press the bottom part of the
power door lock switch
located on either front door
to lock all the doors at once.
Press the top of the switch
to unlock all the doors
at once.
The power door lock switches located on the rear doors
can also lock all the doors at once by pressing the
bottom part of them, but they cannot unlock the doors.
Automatic Door Locks
Your vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved out
of PARK (P), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever back into PARK (P). If someone needs to get
out while your vehicle is not in PARK (P), have that
person use the manual lever or power lock switch. When
the door is closed again, it will not lock automatically.
Use the manual lever or power lock switch to lock the
door again. If you need to lock the doors before shifting
out of PARK (P), use the manual lever or power lock
switch to lock the doors.
Programmable Automatic Door Locks
With the ignition in ON, the door locks can be
programmed through prompts displayed by the Driver
Information Center (DIC). These prompts allow the
driver to choose various lock settings. For programming
information, see ªVehicle Programming and
Personalization Featuresº in the Index.

Rear Door Security Locks
Your vehicle is equipped
with rear door security
locks that help prevent
passengers from opening
the rear doors of your
vehicle from the inside.
To use this lock:
1. Turn the knob on the passenger's side rear
door clockwise all the way down to the
ENGAGED position.
2. Close the door.
3. Turn the knob on the driver's side rear door
counterclockwise all the way down to the
ENGAGED position.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use.When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door from the inside.
2. Then open the door from the outside.
To cancel the rear door lock, do the following:
1. Unlock the door and open it from the outside.
2. Turn the knob on the passenger's side of the rear
door counterclockwise all the way back to the
original position.
3. Turn the knob on the driver's side of the rear door
clockwise all the way back to the original position.
The rear door locks will now work normally.
Anti-Lockout Feature
Leaving your key in any ignition position with any
door open will disable the use of the power door lock
switches as well as the lock button on the remote keyless
entry transmitter. If you close the doors, you can lock
them using the remote keyless entry transmitter. It is
always recommended that you remove the ignition key
when locking your vehicle.
Also, the anti
-lockout feature can be overridden by
holding the driver's power door lock switch for three
seconds or longer.

Operation
When you press this
symbol to unlock the
driver's door, the parking
lamps on your vehicle
will flash twice. You can
program your vehicle
so the parking lamps
will not flash.
(For more information,
see ªLock/Unlock
Confirmationº in the Index.)
The parking lamps will also not flash if they have been
turned on manually. Pressing this symbol again within
five seconds will unlock the other doors. Pressing this
symbol will disarm the theft
-deterrent system and turn
on the interior lamps at night.
When you press this symbol to lock the doors,
the parking lamps will flash once and the horn will
sound. The parking lamps will not flash, however, if the
manual parking lamps are left on. (You can program
your vehicle so the parking lamps will not flash and
the horn will not sound. For more information,
see ªLock/Unlock Confirmationº in the Index.)
This arms the theft
-deterrent system.
Press this symbol to open the trunk. (The VALET
lockout switch must be off for this feature to work.)
Your transmitter comes equipped with an
instant panic alarm. To use the alarm, press the horn
symbol with the ignition off. The horn will sound and
the exterior lamps will flash for up to 30 seconds.
To stop the instant panic alarm, press the symbol
again or turn the ignition to ON.
The remote keyless entry transmitter can be used
to recall the memory settings for up to two drivers.
For more information, see ªMemory Seat, Mirrors
and Steering Wheelº in the Index.

Trunk Release Handle (If Equipped)
NOTICE:
The trunk release handle was not designed to be
used to tie down the trunk lid or as an anchor
point when securing items in the trunk. Improper
use of the trunk release handle could damage it.
There is a glow-in-the-dark trunk release handle
located inside the trunk near the latch. This handle will
glow following exposure to light. Pull the release handle
up to open the trunk from the inside.
Theft
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. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.

2-17
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
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.

Move the valet lockout switch to ON.

Leave only the valet key.

Take all other keys and the Remote Keyless Entry
transmitter with you.
Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will flash,
reminding you to activate
the system.
The light will also flash if the battery has been
disconnected and reconnected.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all the doors. The SECURITY light should go
off within about 30 seconds.
When the theft
-deterrent system activates, the horn will
sound and the lamps will flash for about 30 seconds
when the door or trunk is opened without the key or the
remote keyless entry transmitter.

2-19
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.
