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.

1-30
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 an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also 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 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 the air
bag module and seatback for the driver's side
impact air bag. Do not open or break the air
bag coverings.

Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To do
this, press the LOCK and UNLOCK buttons on the
transmitter together and hold for approximately seven
seconds or until one brief horn chirp is heard.
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 VENT. 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.

Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled and the
engine will not start.
During normal operation, the SECURITY message will
be displayed after the key is turned to the ON ignition
position. See ªMessage Center, Securityº in the Index.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if you turn
the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock at this time. You
may also want to check the fuse (see ªFuses and Circuit
Breakersº in the Index). See your dealer for service.
In an emergency, contact Chevrolet Roadside
Assistance. See ªRoadside Assistanceº in the Index for
more information.
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, you can turn the switch to
four positions.
The ignition switch is
located on the instrument
panel, to the right of the
steering column.
OFF: This is the only position from which you can
remove the key. Removing the key locks your ignition
and automatic transaxle.
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? 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.
ACC (Accessory): This is the position in which you
can operate your electrical accessories. With the key
in this position, the ignition and automatic transaxle
will unlock.
ON: This is the position to which the switch returns
after you start the engine and release the switch. The
switch stays in ON when the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical accessories and to display some
instrument panel cluster messages and warning lights.

2-32
START: This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning chime will sound if you open the driver's
door while the ignition is in OFF or ACC and the key is
in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), your power
windows, audio system and sunroof (option) will
continue to work for up to 10 minutes after the ignition
is turned to OFF and none of the doors is 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 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.
Starting Your 3400 V6 Engine
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 warms up.
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.
