1 Used Replacement Wheels
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have
a
collision in which you or others could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire
chain clearance
to the body and chassis.
See “Changing a Flat Tire”
in the Index for more
information. Putting
a used wheel
on your vehicle is
dangerous. You can’t know how it’s been used or
how far it’s been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new
GM original equipment wheel.
Tire Chains
NOTICE:
If your Buick has P225/60R16 size tires, don’t use
tire chains. They can damage your vehicle
because there’s not enough clearance.

NOTICE: (Continued)
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions.
To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels.
If you do find traction devices that will fit, install
them on the front tires.
If you have other tires, use tire chains only where
legal and only when you must. Use only
SAE Class
“S” type chains that are the proper size for your
tires. Install them on the front tires and tighten
them
as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If the contact continues, slow down until it
stops. Driving too fast or spinning the wheels with
chains on
will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can
burst into flame if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When you use anything from
a container to clean your
Buick, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows
when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
0 Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous
-- some more than others --
and they can all damage your vehicle, too.

Finish Care
Occasional waxing or mild polishing of your Buick by
hand may be necessary to remove residue from the paint
finish. You
can get GM-approved cleaning products
from your dealer. (See “Appearance Care and Materials”
in the Index.)
Your Buick has a “basecoatklearcoat” paint finish.
The clearcoat gives more depth and gloss to the
colored basecoat. Always
use waxes and polishes that
are non-abrasive and made for a basecoatklearcoat
paint finish.
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 or
Chrome 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.
You may use chrome polish
on chrome wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
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.

Cleaning Tires Sheet Metal Damage
To clean your tires, use a stiff brush with a tire cleaner. 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
NOTICE: replaced to restore corrosion protection.
When applying a tire dressing always take care
to wipe off any overspray or splash from all
painted surfaces on the body or wheels of the vehicle. Petroleum-based products may damage
the paint finish.
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.
