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 RUN or START, a chime 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 come on and stay
on until the driver’s belt
is buckled.

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 AIR BAG or
the air bag symbol.
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
You will see this light flash
for
a few seconds when you
turn your ignition to
RUN
or START. Then the light
should go out. This means
the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays on, or comes
on when you
are driving, your air bag system may
not work properly.
Have your vehicle serviced right away.
Charging System Light
VOLTS
The charging system light
will come on briefly when
you turn on the ignition,
as
a check to show you it’s
working. Then it should
go out.
If it stays on, or comes on while you are driving, you
may have
a problem with the charging system. It could
indicate that you have a loose 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.

(Service Engine Soon Light)
I
SERVICE
ENGINE
SOON
Your Chevrolet 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. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) 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, which
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 is 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 brandsl’of fuel? Oil Warning Light
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 this condition, 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
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 oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in two other situations:
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.

Downloaded from www.Manualslib.com manuals search engine 0 If you make a hard stop, the light may come on for a
moment. This is normal.
Low Oil Level Light
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by your
warranty.
LOW
OIL
Your engine is equipped
with an oil level monitoring
system. When the ignition
key
is turned on, the LOW
OIL light will briefly flash.
If the light does not flash,
have
it fixed so it will be
ready to warn you if there’s
a problem.
If the light stays on, stop the vehicle on a level surface
and turn
the engine off. Check the oil level using the
engine oil dipstick. (See “Engine Oil”
in the Index.)
If the light does not flash, have the low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
The oil level monitoring system only checks oil level
during the brief period between key
on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check
is
only performed if the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation to drain back into the oil pan.

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 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.
Care of Your Cassette Tape Player
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 CLN to indicate
that you have used your tape player for
50 hours without
resetting
the tape clean timer. If you notice a reduction in
sound quality,
try a known good cassette to see if the tape
or the tape player is at fault.
If this other cassette has no
improvement
in sound quality, clean the tape player.
Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning. Insert
the cassette at least three times to ensure thorough cleaning.
A scrubbing action cleaning cassette is
available through your Chevrolet dealer.
