If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
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 asdesigned.
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 warned
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.

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
comes 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.
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:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

the player. Try a new tape to be sure your
player is working properly.
0 The cassette tape is broken. (Check to see if your
tape is broken.
Try a new tape.)

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
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 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.
ANTI -
LOCK
-.
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 Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
Since you can’t see as well, you may need to slow
down and keep more space between you and other
vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
0 If you’re tired, pull off the road in a safe place and
rest.
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.
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. 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 City Driving
One of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals. Here are
ways to increase your safety
in city driving:
0 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.
0 Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)
0 Treat a green light as a warning signal. A traffic light
is there because the comer 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.
