PASS-Key@ I1
Your vehicle is equipped
with the PASS-Key
II
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
I1 is a passive
theft-deterrent system. It
works when you insert or
remove the key from
the ignition.
PASS-Key I1 uses a resistor pellet in the ignition key
that
matches a decoder in your vehicle.
When the PASS-Key
I1 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 stays on
when you try to start the vehicle, 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 fuses (see “Fuses and Circuit Breakers’’ 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
11.
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
I1 to have a new key made.

3. If your enpe still won’t start (or starts but then stops),
it could be flooded with too much gasoline. Try
pushing your accelerator pedal
all the way to the floor
and holding it there as you hold the key in START for
about three seconds. If the vehicle
starts briefly but
then stops again, do the same
thing, but this time keep
the pedal down for five
or six seconds. This clears 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
1 equipment, check with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
~ Your Vehicle” in the Index.
Starting Your 5.7 Liter LS1 Engine
1. Without pushing the accelerator pedal, turn the
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
I
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.
2. If it doesn’t start within 10 seconds, push the
accelerator pedal all the way to the
floor, while you
hold the ignition key in START. When the engine starts, let
go of the key and let up on the accelerator
pedal. Wait about
15 seconds between each try to
help avoid draining your battery
or damaging
your starter.
2-27

When starting your engine in very cold weather (below
0°F or -18”C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to
START and hold it there. When the
engine starts, let
go of the key. Use the accelerator
pedal to maintain engine speed, if you have to, until your engine has run
for a while.
2. If your engine still won’t start (or starts but then
stops), it could be flooded with
too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing, but
this time keep the pedal down for five or six seconds.
This clears the extra gasoline from the engine.

Warning lights come on when there may be or is a
problem with one
of your vehicle’s functions. As you
will see in the details
on the next few pages, some
warning lights come on briefly
when you start the
engine just to let you know they’re working.
If you are
familiar with this section,
you should not be alarmed
when this happens.
Gages
can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to
let you know when
there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to
do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Safety Belt Reminder Light
When the key is turned to RUN or STMT, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about
70 seconds. If the
driver’s belt is already

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR
BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes
the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR
BAG
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should
go out. This means
the system is ready.
If the air bag readiness light stays
on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for
a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.
Voltmeter
You can read battery
voltage on your voltmeter.
If it reads less than 11 volts
or more than 16 volts while
your engine is running, and
it stays there, you may have
a problem with the
electrical charging system.
Have it checked right away. Driving with the voltmeter
reading in a warning zone could drain your battery.
If you idle your engine for a while, the voltmeter
reading might move into
the yellow zone. If the reading
stays in the yellow zone while you are driving, you may
have a problem with the electrical charging system.
Have
it checked. While the voltmeter reads in the yellow
zone, your battery may not be able to power certain electrical accessories, like
ABS. (If this happens, your
ABS INOP light will come on. See “Anti-Lock Brake
System Warning Light” in the Index.

Low Coolant Light (5.7L V8 Engine)
This warning light should
come on while you are
starting your engine.
If the
light doesn’t come on, have
it repaired.
~
Your vehicle is equipped with a low coolant indicator
which is designed to detect when the coolant level drops
below set limits.
If the low coolant level sensor (on the
radiator) drops while the engine is running, the low
coolant indicator will light and remain lit until the
ignition
is turned to OFF. Check coolant level and add
coolant as needed. The low coolant light might stay on
after filling the radiator. Turn the ignition to
OFF, then
restart
the engine to verify that the low coolant light
goes out. See “Engine Coolant” in the Index.
NOTICE:
Driving with the low coolant light on could cause
your vehicle to overheat. See “Engine Overheating”
in the Index. Your vehicle could be damaged and it
wouldn’t be covered by your warranty.
Malfunction Indicator Lamp
(Service Engine
Soon Light)
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
2-85

This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions
are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent.
This may
prevent more serious damage to your vehicle.
This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while,
your emission controls may not
work as well, your fuel economy
may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfiie increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
\*
0
/
0 120
3800 V6 Engine 5.7L VS Engine
One of these gages may tell you there could be a
problem with
your engine oil pressure.
The engine oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) in the United States, or kpa
(kilopascals)
in Canada, when the engine is running. On
the 5.7L V8 engine, oil pressure should be 20 to 80 psi
(140 to 550 Pa). On the 3800 V6 engine, the oil pressure
should be between 20 and 120 psi (140 to 827 Wa). It
may vary with engine
speed, outside temperature and oil
viscosity, but readings above the red area show the normal
operating range. Readings
in the red area tell you that the
engine is low
on oil, or that you might have some other oil
problem. See “Engine Oil” in the Index.
