If it doesn’t start right away, hold your key in
START. If it doesn’t start in three seconds (or starts
but then stops), push the accelerator pedal about one-quarter
of the way down for 12 more seconds, or
until it starts.
If your engine still won’t start (or starts but then
stops), it could be flooded with too much gasoline.
Try this:
Wait
15 seconds to let the starter motor cool down.
Then push your accelerator pedal all the way to the
floor. Hold it there. Then hold the key
in START.
This clears the extra gasoline from the engine. When
the engine starts, let go
of the key and the accelerator
pedal.
If the engine still doesn’t start, wait another
15 seconds and repeat this step.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the
way
the engine operates. Before adding electrical
equipment, check with your retailer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to
do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.

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.
The safety belt light will
also come on and stay on
for about
70 seconds. If the
driver’s belt is already
buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows a deployed 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
module, the wiring and the diagnostic module. For more
information on the air bag system, see “Air Bag” in
the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. 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. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN. 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 Indicator Light
The charging system light
will come on when you turn
on the ignition as a check to
show you it is working. It
will remain on as long as
the engine is not running.
It should go out once the engine is running.
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 problems with a 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
When the ignition is on, the brake system warning light
will come on when you set your parking brake.
The light
will stay on if your parking brake doesn’t release fully.
If
it stays on after your parking brake is fully released, it
means you have
a brake problem.
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.

The traction control system warning light may come on
for the following reasons:
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays
on for an extended period of time when the
system
is turned on, your vehicle needs service.
Low Traction Light (Option)
LOW
TRACTION
If your vehicle has the
traction control system,
there will be a
LOW
TRACTION light on the
instrument panel.
When your anti-lock system is adjusting brake pressure
to help avoid a braking skid, or when your traction
control system is limiting wheel spin, the
LOW
TRACTION light will come on. Slippery road
conditions may exist if this light comes on,
so adjust
your driving accordingly. The light will come on and
stay
on for four seconds when your anti-lock system
adjusts brake pressure for less than four seconds or
when your traction control system limits wheel spin for
less than four seconds. Otherwise, the light will
go out
as soon as the anti-lock system
stops adjusting brake
pressure or the traction control system stops limiting
wheel spin.
The
LOW TRACTION 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 system is active.

Low Coolant Light
If this light comes
on, your system is low
on coolant and the
engine may overheat.
To prevent damage to your engine, immediate
action
is required.
See “Engine Coolant” in the Index and have your
vehicle serviced
as soon as possible.
Malfunction Indicator Lamp (Service Engine Soon Light)
SERVICE
ENGINE
SOON
United States
CHECK
Canadian
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 SERVICE ENGINE SOON light
comes on and
a chime will sound 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.
2-93
ProCarManuals.com

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. Retailer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Retailer 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.
Avoiding hard accelerations.
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
retailer or qualified service center for service.

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 fwl?
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 retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

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.
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 retailer and be sure to check Federal rules
covering mobile radio and telephone units.

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 (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
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
a little. (You may also hear a clicking
noise if you leave the ignition in the
RUN position for
about four seconds before starting the vehicle.) This
is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light’’ in the Index.
