Downloaded from www.Manualslib.com manuals search engine 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 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 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.
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 and
modules, the wiring and the diagnostic module. For
more information on the
air bag system, see “Air Bag”
in the Index.
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.
Brake System Warning Light
Your Chevrolet’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.
This light should come on briefly as you start the
vehicle.
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, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your
Car” in the
Index.)

Downloaded from www.Manualslib.com manuals search engine The ASR system warning light may come on for the
following reasons: Low Traction Light
If you turn the system off by pressing the button
located on the console near the cigarette lighter, the
warning light will come
on and stay on. To turn the
system back
on, press the button again. The warning
light should
go off. (See “ASR System” in the Index
for more information.)
0 If the temperature of the throttle control begins to
rise, the system will turn off and the warning light
will come on until the system cools down. The
system
does this to prevent damage from
overheating.
If the ASR system warning light comes on and stays on
for an extended period of time when the system is
turned on, your vehicle needs service. When your anti-lock
system is adjusting brake pressure to help avoid a braking skid, the LOW TRAC light will
appear on your instrument cluster. If you have the
ASR
system, this light will also come on when the system is
limiting wheel spin. Slippery road conditions may exist
if this light comes
on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the anti-lock system stops adjusting brake pressure
or the
ASR system stops limiting wheel spin.
The
LOW TRAC light also comes on briefly, as a bulb
check, when
the engine is started. If the light doesn’t
come
on then, have it fixed so it will be there to tell you
when the anti-lock brake system or
ASR system is active.

SERVICE
ENGINE SOON
A computer monitors operation of your fuel, ignition
and emission control systems. This amber indicator light
should come
on when the ignition is on, but the engine
is
not running, as a check to show you it is working. If it
does not come on at all, have it fixed right away. If
it
stays on, or it comes on while you are driving, the
computer is indicating that you have a problem. You
should take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light
on, after a while the emission controls won’t
work as well, your fuel economy won’t be as good
and your engine may not run
as smoothly. This
could lead to costly repairs not covered by your
warranty.
OBD I1 3800 L36 Engine (Code K)
Certain vehicles are equipped with a new emission
diagnostic system. You can tell whether your vehicle has
this system by reading your tune-up label Iocated under
the hood. If the label says OBD I1 on it, the following
instructions apply.
Your Chevrolet is equipped with an onboard computer
which monitors operation
of the emission control
system. 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

comes on to indicate when service is required.
Malfunctions often will be indicated by the system

Downloaded from www.Manualslib.com manuals search engine 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.
The SERVICE ENGINE
SOON light should come on,
as a check to show you it is working, when the ignition
is on and the engine is not running. This light will also
come on during a malfunction in one of two ways:
Light on steady - indicates a system malfunction has
been detected. Drive the vehicle to the dealer for
service at your first opportunity.
0 Light flashing - indicates a misfire has been detected
which may damage the emission control system. The
damage may be reduced by lowering the vehicle
speed, reducing the amount of cargo being hauled or
trailered, avoiding hard acceleration, or
by avoiding
steep uphill grades. If these actions are effective, the
light will stop flashing and remain on steady. Drive
the vehicle to a dealer for service. If the light
continues to flash, stop the vehicle. Wait for
a steady
light to come on,
then drive the vehicle to a dealer
for service. These
following conditions also may cause the
SERVICE ENGINE SOON light to come on:
Low Fuel/Out of Fuel
- As the vehicle starts to run out
of fuel the SERVICE ENGINE SOON light may come
on as a result of an engine misfire. Filling your gasoline
tank should correct this condition. Make sure to install
the gas cap fully. It will require a few driving trips to
turn the light off.
Poor Quality Fuel
- Be sure to fuel your vehicle with
quality fuel. Your engine may not run efficiently on poor
fuel.
Poor fuel may cause stalling, hesitation or misfire.
These conditions may go away when the engine is
warmed-up. However, poor quality fuel may cause the
SERVICE ENGINE SOON light to come on.
Have a dealer check the vehicle. If
no problems are
found, you may want to change to another brand of fuel.
Driving Through Standing Water
- Driving your vehicle
through puddles
of deep standing water may result in a
temporary misfire condition. This condition will usually
correct itself shortly after the electrical system dries out.
It will require a few driving trips to turn the light off.

Downloaded from www.Manualslib.com manuals search engine 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 yellow zone.
If the reading
stays in the yellow zone while you are driving, you may
have a problem with the electrical charging system.
Have it checked. While the voltmeter reads in the yellow
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.)
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
systems.

Downloaded from www.Manualslib.com manuals search engine 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 car’s engine, Delco@radio or other systems,
and even damage them. And, 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 cause failure of the tape player.
Your tape player should be cleaned regularly each
month or after every
50 hours of use. 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.

Downloaded from www.Manualslib.com manuals search engine 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 cartridge to eject while cleaning. Insert
I the cassette at least 3 times to ensure thorough cleaning.
A scrubbing action cleaning cassette is available through
your Chevrolet dealership.
You may also chc #e 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. It may not clean as thoroughly
as the scrubbing
type cleaner.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure that 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.
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 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.
0 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.
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
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.)
0 Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
