Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish if
they remain on painted
surfaces. Use cleaners that are marked
safe for painted
surfaces for
these stains.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop
into a major repair expense.
Minor chips and Scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
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 vehicle 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 comes first.

Appearance Care and Maintenance Materials
You can get these from your Buick dealer.

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.

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section
D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before
you or anyone else drives
the vehicle.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE
5W-30 or SAE 10W-30), see “Engine Oil” in
the Index. If your vehicle has an Engine Oil Life
Monitor, the monitor will show
you when to change
the oil. See “Engine Oil Life Monitor” in the Index.
2. Chassis Lubrication -- Lubricate suspension and
steering linkage. Lubricate the transaxle shift linkage, and parking brake
cable guides, underbody
contact points and linkage.
3. Throttle Body Mounting Bolt Torque* -- Check
the torque of the mounting bolts and/or nuts.
4. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following
the instructions in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service” -- Drain, flush and refill
the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant” in
the Index. This provides proper freeze
protection, corrosion inhibitor level
and engine
operating temperature.
* An Emission Control Service.
3‘ The U.S. Environmental Protection Agency has determined that the failure to perfonn this maintenance item will not nullify the emission warranty or limit recall liability prior to thecompletion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.
