Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or
in different words.
You’ll also see warning labels
on your vehicle. They
use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3

Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key@
Ill uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key@ 111 Operation
Your vehicle is equipped with PASS-Key@ Ill
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key@
Ill is a passive
theft-deterrent system. This means you don’t have to do
anything special to arm or disarm the system. It works
when you insert or remove the key from the ignition.
When the PASS-Key@
Ill 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 5-97. 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@
Ill to have a new key made. In an
emergency, contact Pontiac Roadside Assistance.
See Roadside Assistance Program
on page 7-5 for
more information.
It is possible for the PASS-Key@
Ill 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.
If all the currently programmed keys are lost
or do not operate, you must see your dealer or a
locksmith who can service PASS-Key@
Ill to have keys
made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key@
Ill to get a new key blank that is cut exactly
as the ignition key that operates the system.
2-1 7

Canadian Owners: If you lose or damage your keys,
only a
GM dealer can service PASS-Key@ Ill to
have new keys made.
To program additional keys, you
will need 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 (black
in color). Then continue with Step 3.
To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master 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.
4. Insert the key to be programmed and turn it to RUN
within five seconds
of removing the original key.
5. 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.
6. Repeat Steps 1 through 5 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@ Ill system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key@
Ill system at this time.
If you lose or damage your PASS-Key@ Ill key, see your
dealer or a locksmith who can service PASS-Key@
Ill
to have a new key made.

Starting and Operating Your
Vehicle
New Vehicle Break-In Ignition Positions
With
the key in the ignition switch, you can turn it to
five different positions. The ignition switch is located
on the right side of the steering column.
Notice: Your vehicle doesn’t need an elaborate
“break-in.” But
it will perform better in the long
run if you follow these guidelines:
e
e
e 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 “Towing a Trailer”
in the Index for
more information. A
(ACCESSORY): This position lets
you use things like
the radio and windshield wipers while the engine is
off. To use accessory, push in the key and turn it toward
you. The steering wheel will stay locked.
3-1 9

Notice: If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key;
if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none
of these works,
then your vehicle needs service.
B (LOCK): This position locks the ignition, steering
wheel and transaxle. It’s a theft-deterrent feature. It’s also
the only position from which you can remove the key.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use
OFF if you must have
the vehicle pushed or towed.
D (RUN): This position is where the key returns to after
you start the vehicle. With the engine
off, you can use
RUN to display some of the warning and indicator lights.
E (START): This position starts the engine.
A warning chime will sound
if you open the driver’s door
while the ignition is in
OFF, LOCK or ACCESSORY
and the key is in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power, (RAP), the power
windows, audio system and sunroof will continue to work
up to
10 minutes after the ignition key is turned to
OFF and none of the doors are opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position - that’s a
safety feature. To restart while you’re already moving,
use NEUTRAL
(N) only.
Nofice: Don’t try to shift to PARK (P) if your
vehicle is moving.
If you do, you could damage the
transaxle. Shift to
PARK (P) only when your
vehicle is stopped.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to
do the following:
Prevent ignition key removal unless the shift lever is
in PARK (P) with the shift lever button fully released.
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than
OFF or
LOCK. The shift lock release is always functional
except in the case
of a dead or low voltage
(less than
9 V) battery.
