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,
8 and it stays there, you may
have a problem with the
electrical charging system.
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 could be a brake
problem. Have your brake system inspected right away.
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 “Anti-Lock Brake System Warning Light”
in this section.)
BRAKE
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.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop.
If the light is still on, have the
vehicle towed
for service. (See “Towing Your Vehicle’’
in the Index.)

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.
In “Problems on the Road” this section shows what to
do. See “Engine Overheating,’’
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 remired. 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 for five minutes or until the ignition switch
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 switch to the
OW position,
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.

with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
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:
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.

Downloaded from www.Manualslib.com manuals search engine 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.

5.7L VS Engine 3800 V6 Engine
This gage tells you if 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 U.S.,
or kPa (kilopascals) in Canada, when the engine is
running. Oil pressure should be
20 to 80 psi (140 to
550 kPa). On the 3800 engine, the oil pressure
should be between
20 and 120 psi (140 to 827 Wa).

Downloaded from www.Manualslib.com manuals search engine 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.
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon
as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.
Low Oil Light
This warning light should
come on while you are
starting your engine.
If
the light doesn’t come on,
have
it repaired.
LOW OIL
I
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil. See “Engine Oil’’ in the Index.
NOTICE:
The oil level monitoring system only checks the
oil level when you are starting your engine. It
does not keep monitoring the level once the
engine is running. Also, the oil level check only
works when the engine has been turned
off long
enough for the
oil to drain back into the oil pan.

CHECK
GAGES
This warning light will
come on briefly when you
are starting the engine.
If the light comes on and stays on while you are driving,
check your gages to see if they are in the warning areas.
Fuel Gage
Your fuel gage shows about
how much fuel is in your
tank. The fuel gage works
only when the ignition is
in the
RUN.
When the gage pointer first indicates empty (E) you still
have a little fuel left (about one to two gallons)
(3.8 to
7.6 litres), but you need to get more fuel right away.
Here are four concerns some owners have had about the
fuel gage. All these situations are normal and do not
indicate that anything
is wrong with the fuel gage.
0 At the gas station, the gas pump shuts off before the
gage reads full
(F).
0 It takes more (or less) gas to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s capacity to
fill it.
0 The gage moves a little when you turn, stop or
speed up.
0 When you turn the engine off, the gage doesn’t go
back to empty (E).

on the radio display.
If the CD changer is checking the magazine for CDs, the
CD symbol will flash on the display until the changer is
ready to play. When a
CD begins playing, a disc and
track number will be displayed. The disc numbers
are
listed on the front of the magazine.
All of the CD functions are controlled by the radio
buttons, except for ejecting the CD magazine.

Downloaded from www.Manualslib.com manuals search engine Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise
if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and
go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it
is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful
to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts
to it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle -- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, Delco Electronics radio or
other systems, and even damage them. Your
vehicle’s systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
