Vehicle Damage Warnings
Also, in this book you will ®nd 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 speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the following

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock
To unlock the trunk from the outside, insert the key into
the lock on the trunk and turn it clockwise. You can
also press the open trunk symbol on the remote keyless
entry transmitter. See
Remote Keyless Entry System
Operation on page 2-5for more information.
The ignition must be off, or, the transaxle must be in
PARK (P), in order for the trunk to open.
Remote Trunk Release
This feature is used to unlock the trunk from inside the
vehicle using the power door lock switch.
Press and hold the
power door lock switch
to the left for one and
one-half seconds to
unlock the trunk.
The transaxle must be in PARK (P) to activate the
trunk release.
2-10

PASS-KeyžIII Operation
Your vehicle is equipped
with 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 special 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 ¯owing 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 STARTING DISABLED DUE TO THEFT
SYSTEM warning message on the Driver's Information
Center (DIC) 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 5-99. 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. In an emergency, contact Pontiac Roadside
Assistance. See
Roadside Assistance Program on
page 7-6for more information.
It is possible for the PASS-Key
žIII decoder to ªlearnº
the transponder value of a new or replacement key.
Up to 10 additional keys may be programmed for
the vehicle. The following procedure is for programming
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
žIII
to have keys made and programmed to the system.
2-16

Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-KeyžIII 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 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 ®ve seconds of removing the original key.5. The SECURITY DISABLED DUE TO THEFT
SYSTEM warning message on the DIC will turn off,
once the key has been programmed. It may not
be apparent that the SECURITY DISABLED DUE
TO THEFT SYSTEM warning message 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 DISABLED
DUE TO THEFT SYSTEM warning message on the DIC
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 your PASS-Key
žIII key, see your
dealer or a locksmith who can service PASS-KeyžIII
to have a new key made.
2-17

Notice:If your key seems stuck in OFF and you
can't turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. 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.
ACC (ACCESSORY):This position lets you use things
like the radio and windshield wipers while the engine
is off.
R(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.
/(START):This position starts the engine. Let go of
the key when the engine starts. The key will return
to the RUN position.
A continuous warning chime will sound and a KEY IN
IGNITION warning message will display on the DIC
if the key is in the ignition in the OFF or ACCESSORY
positions and the driver's door is opened.
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
1. 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.
Notice: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.
2. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2-19

3. If it doesn't start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.
4. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
brie¯y but then stops again, do the same thing.
This time keep the pedal down for ®ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you don't, your engine
might not perform properly.
Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater. In very cold weather, 0ÉF (-18ÉC) or colder,
the engine coolant heater can help. You'll get easier
starting and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32ÉF (0ÉC), use of the coolant
heater is not required.
2-20

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located above the engine air
cleaner/®lter. See
Engine Compartment Overview
on page 5-12for more information on location.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a ®re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord
won't reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don't, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
