2010 BUICK LACROSSE Owner's Manual

Vehicle Care 9-87
Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment to remove dust
and loose dirt. A canister vacuum
with a beater bar in the nozzle may
only be used on floor carpet and
carpeted floor mats. For soils,
always try to remove them first 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. 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.
5. If the soil is not completely removed, use a mild soap
solution and repeat the cleaning
process with plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If the locally
cleaned area gives any impression
that a ring formation may result,
clean the entire surface.
A paper towel can be used to blot
excess moisture from the fabric or
carpet after the cleaning process.
Leather
To remove dust, a soft cloth
dampened with water can be used.
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, steam,
or spot lifters or spot removers,
or shoe polish 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.

9-88 Vehicle Care
Instrument Panel, Vinyl, and
Other Plastic Surfaces
To remove dust, a soft cloth
dampened with water can be used.
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 reflections 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.
{WARNING
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.

Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services. Please read the information under

Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). See Tire
Rotation on page 9‑59.
