Downloaded from www.Manualslib.com manuals search engine 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.
Safety Belt Reminder Light
When the key is turned to ON or START, a tone will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt
is already buckled.
The safety belt light
will also flash until the
driver’s belt is buckled.
If the driver’s belt is already buckled, neither the tone
nor the light
will come on.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the words
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 diagnostic module. For
more information on the air bag system,
see “Air Bag”
in the Index.
AIR
BAG
This light will come on for
a few seconds when you
start your engine. 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.
If the light comes on and
flashes, your
side impact air bag system or safety belt
pretensioner system may not work properly. Have your
vehicle serviced right away.
The air bag readiness light should come on for a few
seconds when
you turn the ignition key to ON. If the
light doesn’t come
on then, have it fixed so it will be
ready
to warn you if there is a problem.
Charging System Light
This light will come on
briefly when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
Then it should go out when
the engine starts.
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 charging
system light
on, be certain to turn off all your
accessories, such as the radio and air conditioner.

(Check Engine Light)
TEMP
Standard Cluster Optional Cluster
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is too
hot! It means that your engine coolant has overheated.
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 manual shows what to
do. See “Engine Overheating” in the Index.
~~ -~
tis
~~ Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
CHECK
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.
2-49

Downloaded from www.Manualslib.com manuals search engine 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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 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.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady
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.
Are you low
on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to 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 Engine Oil Pressure Light
If you have a problem with
your oil, this light may stay
on after you start your
engine or come on when
you are driving.
This indicates that there is not enough oil pressure
to keep your engine properly lubricated and cool.
The engine could be low on
oil, or have some other
oil related problem. Have it fixed right away.
The oil light could also come on in three
other situations.
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 STMT.
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.
Sometimes when the engine is idling at a stop, the
light may blink on and
off. This is normal.
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.

Downloaded from www.Manualslib.com manuals search engine To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
0 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.
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may
not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after
every
50 hours of use. Your radio may display
CLEAN to indicate that you have used your tape player
for
50 hours without resetting the tape clean timer. If
this message appears on the display, your cassette tape
player needs to be cleaned. It will still play tapes, but
you should clean it as soon as possible to prevent
damage to your tapes and player.
If you notice a
reduction in sound quality, try a known good cassette
to see if it is the tape or the tape player at fault.
If this
other cassette has no improvement in sound quality,
clean the tape player.
The recommended cleaning method for your
cassette tape player
is the use of a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealership
(GM Part No. 12344789).

Downloaded from www.Manualslib.com manuals search engine 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 rear quarter panel.

Downloaded from www.Manualslib.com manuals search engine Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This
is a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will
wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That
means better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (Option)
Your vehicle may have anti-lock brakes (ABS). ABS is
an advanced electronic braking system that will help
prevent a braking slud.
ABS
If your vehicle has anti-lock
brakes, this warning light
on
the instrument panel will
come on briefly when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
If there’s a problem with
the anti-lock brake system, the
anti-lock brake system warning light will stay
on or
flash. See “Anti-Lock Brake System Warning Light” in
the Index.

Downloaded from www.Manualslib.com manuals search engine 0 Do not get too close to the vehicle you want to
pass while you’re awaiting an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you’re following a larger
vehicle. Also, you won’t have adequate space if
the vehicle ahead suddenly slows or stops. Keep
back
a reasonable distance.
0 When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
don’t get too close. Time your move
so you will be
increasing speed as the time comes to move into
the other lane.
If the way is clear to pass, you will
have a “running start” that more than makes up for
the distance you would lose by dropping back. And
if something happens
to cause you to cancel your
pass, you need only slow down and
drop back again
and wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull out to pass the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.
0 Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough

0
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle
you
just passed may seem to be farther away from you
than it really is.)
Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it
may be slowing down
or starting to turn.
If you’re being passed, make it easy for the
following driver to get ahead of
you. Perhaps you
can ease a little to the right.
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to
steer and constantly seek an escape route or area of
less danger.
