/r CAUTION:
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.
0 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. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall
off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Chevrolet dealer before adding equipment to the
outside of your vehicle. Use regular unleaded gasoline rated
at
87 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA)
for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane is at least
87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, your engine needs service.
But don’t worry if you hear a little pinging noise when
you’re accelerating or driving up a
hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means you have a problem.

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. The
headlamp wiring is protected by fuses, one for each
headlamp, in the fuse block.
An electrical overload will
cause the lamps to turn
off. If this happens, have your
headlamp wiring checked right away.
dshield Wipers
lne windshield wiper motor is protected by an internal
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 electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse block 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 or
goes away.

Downloaded from www.Manualslib.com manuals search engine 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.
If
you ever have a problem on the road and don’t have a
spare fuse, you can borrow one that has the same
amperage. Just pick a feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can. Also, there are spare fuses
in the left side instrument panel door.
There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
compartment fuse block.
Instrument Panel Fuse Block
The instrument panel fuse
blocks are located at each end of the instrument panel.
To access the fuses, open
the fuse panel door by
pulling out.
To replace the door, insert
the hooks at the front end
first, then push the door
in
to the instrument panel to
I secure it.
