Downloaded from www.Manualslib.com manuals search engine Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
and the engine is not
running, as a check to show
you it is working.
Then
it should go out when the engine is started.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical charging
system. It could indicate that you have a loose generator
drive belt, or another electrical problem. Have it
checked right away. Driving while this light is on could
drain your battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.
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.
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
3 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.)

If this light comes on and
stays on, your system is low
on coolant and the engine
may overheat.
See “Engine Coolant” in the Index and have your
vehicle serviced as soon as you can.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your vehicle is equipped
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
CHECK ENGINE 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.

Downloaded from www.Manualslib.com manuals search engine 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
0
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.
0 Avoiding hard accelerations.
0 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 “If
the Light Is On Steady” 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
“If the Light
Is On Steady” following. If
the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.

You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed.
A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off. 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.

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Light
If you have a low engine oil
pressure problem, this light
will
stay on after you start
your engine, or
come on
when you are driving. This indicates that your engine is
not receiving enough oil.
The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately.
The oil light could also come on in three
other situations:
0
0
0
When the ignition is on but the engine is not running,
the light will come on as a test to show you it is
working, but the light will go out when you turn the
ignition
to START. If it doesn’t come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.
If you’re idling at a stop sign, the light may blink on
and then
off.
If you make a hard stop, the light may come on for a
moment. This is normal.
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.

This light will come on
CHECK
GAGES
brieflywhen you are
starting the engine.
If the light comes on and stays on while you are driving,
check your various gages to see if they are in the
warning zones or if you
are low on fuel.
:age

When the ignition is on,
your fuel gage tells you about how much fuel you
have left. When the indicator nears
E (EMPTY), you
still have a
little fuel left, but you should get more soon.
Here are four things that
some owners ask about. None
of these show a problem with your fuel gage:
0
0
0
0
At the service station, the gas pump shuts off before
the gage reads
F (FULL).
It takes a little more or less fuel to fill up than the
gage indicated.
For example, the gage may have
indicated the tank was half full, but it actually
took a
little more or less than half the tank’s capacity to
fill
the tank.
The gage moves a little when you turn a comer or
speed up.
The gage doesn’t go back to
E (EMPTY) when you
turn
off the ignition.
For your fuel tank capacity, see “Capacities and
Specifications” in the Index.

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 S m
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:
Adjust the volume control to the lowest setting.
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.
Increase volume slowly until you hear comfortably
and clearly.

seconds. The tape symbol on the display will flash
for two seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own.
A non-scrubbing action cleaner may
not clean
as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette
is not recommended.
After you clean the player, press and hold EJECT for
five seconds to reset the
CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never
to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the fender.
