a plate in the front corner
of the instrument panel, on the
driver’s side. You can see it if you look through the
windshield from outside your vehicle.
The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates
of title and registration.

The eighth character in your VIN is the engine code for
your
GM engine. This code will help you identify your

Add-on
Electrical Equipment
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
of it can just kee
from working as they should.

Fuses and Circuit Breakers
The wiring circuits in your car 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.
You’ll find some spare
fuses in the fuse block. Be sure
to use the correct fuse.
If you ever have a problem on
the road and don’t have a spare fuse,
you can “borrow”
one
of the correct value. Just pick some feature of your
car that
you can get along without -- like the radio or
cigarette lighter
-- and use its fuse, if it is of the value
you need. Replace it as soon as you can.
The fuse panel
is located under the instrument panel,
next to the parking brake.
To release and lower the fuse
panel, squeeze the two tabs together. Then, pull it
towards you.
It will come down so the fuses can be
accessed.

This fuse chart shows how to tell a blown fuse from a
good fuse.
There are additional fuses located behind the right sound
insulator panel on the passenger side. If these require service, see your Buick dealer.
Maxifuse/Relay Center
To check the fuses in this underhood fuse center, turn
the two knobs 1/4 turn counterclockwise and remove the
cover. The inside
of the cover has a chart that explains
the features and controls governed by each fuse and
relay.
The PASS-Key fuse is located in the right side relay center.
Headlights
The headlight wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights to go on and
off, or in some cases to remain off. If
this happens, have your headlight wiring 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 electrical problem and
not snow, etc., be sure to get it fixed.
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 or goes
away.

Protection I
Plan I
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties. See
your Buick dealer for details.
Introduction
A Word About Maintenance
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly
how you’ll drive it. You may drive very short
distances
only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work, to do errands or in many other
ways.
Because of all the different ways people
use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you will
find in the schedules in this part.
So please read this part
and note how
you drive. If you have any questions on
how to keep your vehicle in good condition,
see your
Buick dealer, the place many GM owners choose to
have their maintenance work done. Your dealer can be
relied upon to
use proper parts and practices.
