parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change.
If you use these, you
don’t need
to add anything else.
I k!, CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too
hot but you wouldn’t get the overheat
warning. Your engine could catch fire
and you or
others could be burned.
Use a 5050 mix of clean
water and a proper antifreeze.
I
I NO IC i:
IT you use an Improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered
by your
warranty.
Too much water in the mix can treeze
and crack the engine, radiator, heater core and other
parts.
Adding Coolant

What to Add:
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only.

Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good braking. Vehicles
we design and test have top-quality GM brake
parts in them, as your Buick does when it is new. When
you replace parts of your braking system -- for example,
when your brake linings wear down and you have to
have new ones put in
-- be sure you get new genuine
GM replacement parts.
If you don’t, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change,
for the worse. The braking performance you’ve come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
Battery
Every new Buick has a Delco Freedoms battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedoms
battery. Get one that has the catalog number shown
on
the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, take
off the black, negative (-) cable from the
battery. This will help keep your battery from running
down.

Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask

Mix Multi-Purpose Powdered Cleaner following the
directions on the container label.
Use suds
only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.

a clean, wet sponge.

Using Solvent-Type Cleaner on
Fabric

Some spots and stains will clean off better with just
water and mild soap.

Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start
at the outside of
the stain, “feathering” toward the center. Keep
changing to a clean section of the cloth.
When you clean a stain from fabric, immediately dry
the area with an air hose, hair dryer, or heat lamp to
help prevent a cleaning ring. (See the previous
NOTICE.)

Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter,
margarine, shoe polish, coffee with cream, chewing
gum, cosmetic creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.
Shoe polish, wax crayon, tar and asphalt will stain if
left on a vehicle seat fabric. They should be removed
as soon as possible. Be careful, because the cleaner
will dissolve them and may cause them to bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg,
fruit, fruit juice, milk, soft drinks, wine, vomit, urine and
blood.
Carefully scrape off excess stain, then sponge the
soiled area with cool water.
If a stain remains, follow the foam-type instructions
above.
If an odor lingers after cleaning vomit or urine, treat
the area with a waterbaking soda solution:
1
teaspoon (5 ml) of baking soda to 1 cup (250 ml) of
lukewarm water.
0 Finally, if needed, clean lightly with solvent-type
cleaner.
Combination Stains: Like candy, ice cream,
mayonnaise, chili sauce and unknown stains.
Carefully scrape off excess stain, then clean with
cool water
and allow to dry.
0 If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl or Leather
Just use warm water and a clean cloth.
Rub with a clean, damp cloth to remove dirt. You
Things like tar, asphalt and shoe polish will stain if may have to do it more than once.
you don’t get them
off quickly. Use a clean cloth and
solvent-type vinylbeather cleaner.
Cleaning the Top of the Instrument
Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.

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.

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.
