1996 CHEVROLET EXPRESS check engine light

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing Are you low on fuel?
The following may prevent more serious damage
to
your vehicle:
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
If 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
--IT
the Light Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). 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 dealer 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 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. 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 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.

The fuel gage, when the
ignition is on, tells you
about how much fuel you
have left
in your tank.
If the light comes on and stays on while you are driving,
check your coolant temperature
and engine oil pressure
gages to see
if they are in the warning zones. The
gage will first indicate EMPTY
(E) before you
are out of fuel, and you should get more fuel as soon
as possible.

Your power antenna will look its best and work well if it’s
cleaned from
time to time. To clean the antenna mast:
1. Turn on the ignition and radio to raise the antenna.
2. Dampen a clean cloth with mineral spirits or
equivalent solvent.
3. Wipe the cloth over the mast sec
any dirt.
4. Wipe dry with a clean cloth. rtions,
removing
5. Make the antenna go up and down by turning the
radio or ignition off and
on.
6. Repeat if necessary.
I NOTICE:
Don’t lubricate the power antenna. Lubrication
could damage it.
NOTICE:
Before entering an automatic car wash, turn off
your radio to make the power antenna go down.
This will prevent the mast from possibly getting
damaged.
If the antenna does not go down when
you turn the radio
off, it may be damaged or
need to be cleaned. In either case, lower the
antenna by hand by carefully pressing the
antenna down.
If the mast portion of your antenna is damaged, you can
easily replace
it. See your dealer for a replacement kit
and follow the instructions in the kit,
Adjustable Mast Antenna
The mast should be fully retracted before entering
any automated wash facility
to minimize the risk of
antenna damage.
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 antenna is
still tightened to the body side panel.

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. This is normal.

Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
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.
If you’re tired, pull off the road in a safe place
and rest.
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 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:
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.
most large cities. You’ll save time and energy. (See
the
next part, “Freeway Driving.”)
Try to use the freeways that rim and crisscross
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.
4-18

Downloaded from www.Manualslib.com manuals search engine Once you are moving on the freeway, make certain
you allow a reasonable following distance. Expect to
move slightly slower
at night.
When
you want to leave the freeway, move to the
proper lane well in advance. If
you miss your exit, do
not, under
any circumstances, stop and back up. Drive
on
to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer,
not
to your sense of motion. After driving for any distance
at higher speeds,
you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re
not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to
go. If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in GM
dealers all across North America. They’ll be ready and
willing to help
if you need it.

Tire Inflation Check
Make sure tires are inflated to the correct pressures. See
“Tires” in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep
a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag covers,
and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission”
in the Index. A fluid loss
may indicate
a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part
D.
Body Lubrication Service
Lubricate all hood hinges, hood prop rod pivot, fuel
filler door, rear compartment hinges, latches, locks and
any moving seat hardware. Door hinges are lubricated
for the life
of your vehicle; no additional lubrication is
required. Part
D tells you what to use. More frequent
lubrication may be required when exposed
to a
corrosive environment.
