When to Chang( Cngine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine
oil to break
down sooner.
If any one of these is true for your vehicle,
then you need to change your oil and filter every
3,000 miles (5 000 km) or 3 months -- whichever occurs
first. (See “Change Oil Soon” Light in the Index.)
If none
of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower. (See
“Change Oil
Soon” Light in the Index.)
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies
of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any
of these
conditions, the fluid and filter do not require changing.
See "Scheduled Maintenance Services"
in the Index.
How to Check
Because this operation can be a little difficult, you may
choose
to have this done at your Buick dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on
hot engine parts
or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F (82°C
to 93 " C).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may have
to drive longer.

Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
J
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating or if you need to add coolant to your
radiator, see “Engine Overheating”
in the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered
by your new vehicle warranty.

What to Use
Use a mixture of one-half dean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts. If
you use this mixture,
you don’t need
to add anything else.
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
50150 mix of clean
water and
DEX-COOL@ coolant.
NOTICE:
If 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 freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

Brake Wear
NOTICE:
0
0
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index. Your
Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time
your vehicle is moving (except when
you are
pushing on the brake pedal firmly).
I
I
The brake wear warning sound means that soon
your brakes won’t work well. That could lead
to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

to remove the suds.
6. Rinse the section with a clean, wet sponge.
7. Wipe off what’s left with a slightly damp paper towel
or cloth.
8. Dry it immediately with a blow dryer.
9. Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If you need to use a solvent:
1. Gently scrape excess soil from the trim material with
a clean, dull knife
or scraper.
2. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start
at the
outside
of the stain, “feathering” toward the center.
3. Keep changing to a clean section of the cloth.
4. When you clean a stain from fabric, immediately
dry
the area with a blow dryer to help prevent a
cleaning ring.

Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described
earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them
to spread.
Non-Greasy Stains
Stains caused by catsup, coffee (black), egg, fruit, fruit
juice, milk, soft drinks, wine, vomit, urine and blood can
be removed as follows:
1. Carefully scrape off excess stain, then sponge the
soiled area with cool water.
2. If a stain remains, follow the foam-type instructions
described earlier.
3. If an odor lingers after cleaning vomit or urine,
treat the area with a waterhaking
soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup (250 ml)
of lukewarm water.
4. If needed, clean lightly with solvent-type cleaner.
Combination Stains
Stains caused by candy, ice cream, mayonnaise, chili
sauce and unknown stains can be removed as follows:
1. Carefully scrape off excess stain.
2. Clean with cool water and allow to dry.
3. If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl
Use warm water and a clean cloth.
Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.
Things like tar, asphalt and shoe polish will stain
if you don’t get them
off quickly. Use a clean
cloth and a vinyl/leather cleaner. See your dealer for
this product.

Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with
a soft cloth. Then, let the
leather dry naturally.
Do not use heat to dry.
0 For stubborn stains, use a leather cleaner. See your
dealer for
this product.
0 Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish
on leather.
Soiled or stained leather should be cleaned
immediately.
If dirt is allowed to work into the
finish, it can harm the leather.
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.
Cleaning the Built-in Child Restraint
Your built-in child restraint may be cleaned with mild
soap
and lukewarm water. Don’t use household cleaners.
They may weaken the harness or damage plastic parts.
The built-in child restraint pad is attached to the child
restraint cushion and seatback with fastener strips. You
can remove the pad, machine wash it in cold water
on a
gentle cycle and tumble dry it
on a low heat setting.
Never bleach or iron the pad, and don’t dry clean it.

NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint finish may dull the
finish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and
tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle’s finish if they remain on painted
surfaces. Wash the vehicle as soon as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over
a period
of years.
You can help to keep the paint finish looking
new by keeping your Buick garaged
or covered
whenever possible.
Cleaning Aluminum Wheels
(If Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel.
A wax
may then be applied.
The surface
of these wheels is similar to the painted
surface of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes on them because you could
damage the surface.
Don’t take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
