Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we 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 may be equipped with 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 in the Index:

ªEngine Compartment Overviewº

ªInstrument Panelº

ªComfort Controlsº

ªAudio Systemsº
Also see ªWarning Lights and Gagesº in the Index.

CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation and driver's
safety belt usage at deployment. The module also
records speed, engine rpm, brake and throttle data.

Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
system won't work properly. See your dealer for service.
NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, or the air bag
covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

Resynchronization
After replacing the battery in your transmitter, or if
only the instant alarm works, the transmitter needs to be
resynchronized to the receiver. Do this by pressing and
holding both the button with the lock symbol and the
button with the unlock symbol at the same time for
about eight seconds. You must be within range of
the vehicle.
Once the transmitter has been resynchronized, the horn
will chirp and the exterior lamps will flash once. The
system should now operate properly.
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 with the setting
on any airflow selection except RECIRC.
That will force outside air into your vehicle.
See ªComfort Controlsº 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.

2-22
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 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 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.
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 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 ªPK3º stamped on it.
2. Insert the current driver's key in the ignition and
start the engine. If the engine will not start, see your
dealer for service.

2-23
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 10 seconds of removing the previous 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 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.
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.

Ignition Positions
With the key in the ignition switch, you can turn it to
five different positions.
A (ACCESSORY): In this position you can operate
your electrical accessories. Press in the ignition switch
as you turn the top of it toward you.B (LOCK): This is the only position from which
you can remove the key. This position locks your
ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
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? 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 this works, then your
vehicle needs service.
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 and it doesn't send any power to the
accessories. The instrument panel cluster will remain
powered in OFF to illuminate the gear shift indicator. The
cluster will also activate the parking brake light when the
parking brake is set. Use OFF if you must have your
vehicle in motion while the engine is not running.

2-25
D (RUN): This is the position that the switch returns to
after you start your engine and release the ignition key.
This is the position for driving. Even when the engine is
not running, you can use RUN to operate your electrical
accessories and to display some instrument panel
warning lights.
E (START): This position starts your engine. When the
engine starts, release the ignition key. The switch will
return to RUN for normal driving.
Key Reminder Warning
If you leave your key in the ignition, with the engine
off, you will hear a warning chime when you open the
driver's door.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key,
you will still have power to such accessories as the
radio, sunroof (option) and power windows for up
to 10 minutes. Power is stopped if you open a door.
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 when 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.
1. 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.
