BUICK REGAL 1997 Owners Manual

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are
not removed, accelerated corrosion (rust) can occur
on the underbody parts such as fuel lines, frame, floor
pan and exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched
into the paint surface.
Although no defect in the paint
job causes this, Buick
will repair, at
no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.

Vehicle Identification Number (VIN)
r r
ENGINEA997 f ASSEMBLY
CODE MODEL YEAR PLANT
This is the legal identifier for your Buick. It appears on
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.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You’ll find this label on the deck lid. It’s very helpful
if
you ever need to order parts. On this label is:
your VIN,
the model designation,
paint information and
e a list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.

Electrical System
Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Buick
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 Buick, see “Servicing
Your Air Bag-Equipped Buick” 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 electrical problem, have
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.

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
side of the instrument panel.
Pull off the cover labeled
FUSES to expose the fuses.
