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. The SECURITY light may remain on during this
time. 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 ªFuses and Circuit Breakersº 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 II.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 II to have a new key made.
If you're 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 II system, however,
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. In an emergency, call the
Chevrolet Roadside Assistance Center at
1
-800-CHEV-USA
or 1-800-243-8872 (In Canada
call 1
-800-268-6800).

2-26 Starting Your 3800 Series II V6 Engine
1. Without pushing 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. If it doesn't start right away, hold your key in
START for about three to five seconds at a time until
your engine starts. Wait about 15 seconds between
each try to help avoid draining your battery or
damaging your starter.3. 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. 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.
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 ªTowing
Your Vehicleº in the Index.

2-76 Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.
Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.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.

2-77 Safety Belt Reminder Light
When the key is turned to RUN or START, 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
buckled, neither the chime
nor the light will come on.
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 ªAir
Bagº in the Index.
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.

2-78 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 low voltage zone (indicated
by red dots). If the reading stays in the low voltage zone
while you are driving, you may have a problem with the
electrical charging system. Have it checked. While the
voltmeter reads in the low voltage 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 ªAnti
-Lock Brake System Warning Lightº
in this section.)If you must drive a short distance with the voltmeter
reading in a warning zone, turn off all your accessories,
including your air conditioning system and
audio system.
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition key to RUN. If it
doesn't come on then, have
it fixed so it will be ready to
warn you if there's
a problem.

2-81 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, your engine is
approaching an
overheating condition.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Light ( 5.7L V8 Engine)
This warning light should
come on briefly 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
that is designed to detect when the coolant level drops
below the set limit. If the low coolant level sensor (on
the radiator) detects that the level drops while the engine
is running, the low coolant indicator will light and
remain lit until the ignition is turned to OFF. Check the
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 ªEngine
Coolantº in the Index.

NOTICE:
Modifications made to the engine, transmission,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
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:

Light Flashing
-- A misfire condition has been
detected. A misfire 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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
