2-15 Remote Trunk Release Lockout
The trunk release lockout
switch in the glove box
must be on for the TRUNK
button to work. This feature
allows you to secure items
in the trunk when you must
leave the ignition key with
an attendant.
To secure the trunk, turn off the TRUNK RELEASE
switch, lock the glove box, then take the door key with
you. Now the trunk button to the left of the steering
column will not open the trunk.
Trunk Security Override
The remote keyless entry transmitter (if equipped), will
open the trunk even if the trunk release lockout switch
is OFF.
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.
With the ignition off and the driver's door open, 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.
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.

2-16 Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's 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.

Turn off the TRUNK RELEASE lockout in the
glove box.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.
Universal Theft-Deterrent
(If Equipped)
If your vehicle has
this option, it has a
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 theft
-deterrent
system when leaving your vehicle.
Activating the system:
1. Open the door.
2. Lock the door with the power door lock switch while
the door is open, or with the remote keyless entry
transmitter. The SECURITY light should turn 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.

2-17
If the SECURITY light comes on for one minute and
then shuts off while the ignition is on, the security
system has detected a problem with itself. See your
dealer for service.
If a door or the trunk is opened without the key or remote
keyless entry transmitter, the alarm will go off. It will
also go off if the trunk lock is damaged. Your vehicle's
lamps will flash and the horn will sound for one minute,
and then will go off in order to save battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or manual door lock. It
activates only if you use a power door lock switch with
a door open, or 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. You must still shut off the alarm by inserting the key
in the door lock, or by pressing the UNLOCK button on
the remote keyless entry transmitter.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, lock the door by using the door key or the
manual door lock switch.

Always unlock a door with a key, or use the remote
keyless entry system 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 UNLOCK
on the remote keyless entry transmitter, if you have it.
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.
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
II
Your vehicle is equipped
with the PASS
-Key II
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key II is a passive
theft
-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS
-Key II system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. For about three minutes, the starter
won't work and fuel won't go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY light turns on,
the key may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and 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 starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS
-Key II.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will flash. But you don't have to wait
three minutes before trying another ignition key.

See your dealer or a locksmith who can service the
PASS
-Key II to have a new key made.
If you're 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 II system, however,
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. In an emergency, call the
Buick Premium Roadside Assistance Center at

-800-252-1112. In Canada, call 1-800-268-6800.
New Vehicle ªBreak-Inº
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 -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
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.
