Soon Light)
SERVICE
ENGINE
SOON
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.

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.

Downloaded from www.Manualslib.com manuals search engine 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.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes
on when you turn your key to RUN or
START. It goes off once you start your engine. That’s a
check
to be sure the light works. If it doesn’t come on,
be sure to have it fixed so it will be there to warn you if
something goes wrong. When the light
cumes on
and stays on, it means that
oil isn’t flowing through your engine properly. You
could
be low on oil and you might have some other
system problem.
1 A CAUTION:
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: 1
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably

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, 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 or
CLEAN
TAPE 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).

spurts -- heavy acceleration followed by heavy
braking

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. When you
start your engine and 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. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

Downloaded from www.Manualslib.com manuals search engine Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase.
A 50-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you
are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if you’re
driving, don‘t wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several
seconds, for your eyes
to readjust to the dark. When
you are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps. Keep your windshield and all the glass
on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside
of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils
of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a
turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly.
Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren’t even aware of it.

Downloaded from www.Manualslib.com manuals search engine Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get a city map and plan your trip into an
unknown
part of the city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part. “Freeway Driving.”)
Treat a green light as a warning signal. A traffic light
is there because the corner is busy enough to need it.
When a light
turns green, and just before you start
to move, check both ways for vehicles that have not
cleared
the intersection or may be running the
red light.
Freeway Driving
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.
