2009 BUICK LACROSSE Owner's Manual

Do not clean the vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops
per gallon (3.78 L) of water is a good guide.
Use only mild, neutral-pH soaps.
Too much cleaner that saturates the upholstery.
Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only
be used on oor carpet and carpeted oor mats.
For any soil, always try to remove it rst with plain
water or club soda. Before cleaning, gently remove
as much of the soil as possible using one of the
following techniques:
For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the
paper towel until no more can be removed.
For solid dry soils: remove as much as possible
and then vacuum.
To clean:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.
5-91

If any of the soil remains, a commercial fabric cleaner
or spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test
a small hidden area for colorfastness rst. If the
locally cleaned area gives any impression that a
ring formation may result, clean the entire surface.
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
Leather
A soft cloth dampened with water can be used to
remove dust. If a more thorough cleaning is necessary,
a soft cloth dampened with a mild soap solution can be
used. Allow the leather to dry naturally. Do not use heat
to dry. Never use steam to clean leather. Never use spot
lifters or spot removers on leather. Many commercial
leather cleaners and coatings that are sold to preserve
and protect leather may permanently change the
appearance and feel of the leather and are not
recommended. Do not use silicone or wax-based
products, or those containing organic solvents to
clean the vehicle’s interior because they can alter the
appearance by increasing the gloss in a non-uniform
manner. Never use shoe polish on leather.
Instrument Panel, Vinyl, and Other
Plastic Surfaces
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a clean soft cloth dampened with a mild soap solution can
be used to gently remove dust and dirt. Never use spot
lifters or removers on plastic surfaces. Many commercial
cleaners and coatings that are sold to preserve and
protect soft plastic surfaces may permanently change
the appearance and feel of the interior and are not
recommended. Do not use silicone or wax-based
products, or those containing organic solvents to
clean the vehicle’s interior because they can alter the
appearance by increasing the gloss in a non-uniform
manner.
Some commercial products may increase gloss on the
instrument panel. The increase in gloss may cause
annoying reections in the windshield and even make
it difficult to see through the windshield under certain
conditions.

Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. It may severely
weaken them. In a crash, they might not be able
to provide adequate protection. Clean safety belts
only with mild soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather frequent application may be required.
SeeRecommended Fluids and Lubricants on page 6-11.
Washing Your Vehicle
The best way to preserve the vehicle’s nish is to keep
it clean by washing it often.
Notice:Certain cleaners contain chemicals that can
damage the emblems or nameplates on the vehicle.
Check the cleaning product label. If it states that
it should not be used on plastic parts, do not use it
on the vehicle or damage may occur and it would
not be covered by the warranty.
Do not wash the vehicle in direct sunlight. Use a car
washing soap. Do not use cleaning agents that are
petroleum based or that contain acid or abrasives,
as they can damage the paint, metal or plastic on the
vehicle. Approved cleaning products can be obtained
from your dealer/retailer. Follow all manufacturers’
directions regarding correct product usage, necessary
safety precautions and appropriate disposal of any
vehicle care product.
5-93

Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the nish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting.
High pressure car washes may cause water to enter
the vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a
car washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle on
page 5-93.
Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue from
the paint nish. Approved cleaning products can
be obtained from your dealer/retailer.
If the vehicle has a basecoat/clearcoat paint nish,
the clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint nish
may damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint nish on the vehicle.
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 the vehicle’s nish 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.
5-94

Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a
period of years. To help keep the paint nish looking
new, keep the vehicle garaged or covered whenever
possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, chrome polish may be used on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is recommended
for all bright metal parts.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer uid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper removal

Aluminum or Chrome-Plated Wheels
and Trim
The vehicle may have either aluminum or chrome-plated
wheels.
Keep the 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.
Notice:Chrome wheels and other chrome trim
may be damaged if the vehicle is not washed after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such
as ice and dust. Always wash the vehicle’s chrome
with soap and water after exposure.
Notice:Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the warranty. Use only
approved cleaners on aluminum or chrome-plated
wheels.The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes
on them because they could damage the surface.
Do not use chrome polish on aluminum wheels.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by the warranty. Use chrome polish on
chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
Notice:Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the warranty. Never drive a vehicle
equipped with aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
5-96

Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint nish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces
on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop applies anti-corrosion material to parts repaired
or replaced to restore corrosion protection.
Original manufacturer replacement parts will provide
the corrosion protection while maintaining the vehicle
warranty.
Finish Damage
Any stone chips, fractures or deep scratches in the
nish should be repaired right away. Bare metal
will corrode quickly and may develop into major
repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer/retailer. Larger
areas of nish damage can be corrected in your
dealer’s/retailer’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, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where mud
and debris can collect. Dirt packed in close areas of the
frame should be loosened before being ushed. Your
dealer/retailer or an underbody car washing system
can do this.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we
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 rst.
