Downloaded from www.Manualslib.com manuals search engine 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 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 Warning Light
73
OIL
If you have a problem with
your oil, this light may stay
on after
you start your
engine, or come
on when
you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The
oil light could also come on in two other situations:
When the ignition is on but the engine is not running,
the light will come on as a test to show you
it is
working, but the light will go
out when you turn the
ignition to
START. If it doesn’t come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want
to get the proper Chevrolet Service Manual. It tells
you much more about how
to service your Chevrolet
than this manual can.
To order the proper service
manual, see “Service and Owner Publications” in
the Index. Your
vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Chevrolet” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform.
See “Maintenance Record” in the Index.
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance
task.
Be sure to use the proper nuts, bolts and
other fasteners. 44English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off.
You could be hurt.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Chevrolet
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical
to your Chevrolet, see “Servicing
Your Air Bag-Equipped Chevrolet” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. An electrical overload
will cause the lamps
to go on and off, or in some cases
to remain off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If
the overload is caused by some electrica
have it fixed. 1 problem.

Downloaded from www.Manualslib.com manuals search engine Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers,
and fusible thermal links in the wiring itself. This
greatly reduces the chance of fires caused by
electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
Instrument Panel Fuse Block
Some fuses are in a fuse
block on the passenger’s
i side of the instrument panel.
Pull off the cover labeled
FUSES to expose the fuses.
Additional fuses are in the underhood electrical centers
on the right and left sides of the engine compartment.
