Vehicle Care 301have the damage assessed and
repaired. 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 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.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See
your dealer for approved cleaning
products.
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur. CautionMachine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
To keep the paint finish looking new,
keep the vehicle garaged or
covered whenever possible.
Protecting Exterior Bright Metal
Moldings
Caution
Failure to clean and protect the
bright metal moldings can result
in a hazy white finish or pitting.
This damage would not be
covered by the vehicle warranty. The bright metal moldings on the
vehicle are aluminum or stainless
steel. To prevent damage always
follow these cleaning instructions:
.
Be sure the molding is cool to
the touch before applying any
cleaning solution.
.
Use a cleaning solution
approved for aluminum or
stainless steel. Some cleaners
are highly acidic or contain
alkaline substances and can
damage the moldings.
.
Always dilute a concentrated
cleaner according to the
manufacturer ’ s instructions.
.
Do not use chrome cleaners.
.
Do not use cleaners that are not
intended for automotive use.
.
Use a nonabrasive wax on the
vehicle after washing to protect
and extend the molding finish.

304 Vehicle Care disc brake pads for wear and rotors
for surface condition. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components Visually inspect steering,
suspension, and chassis
components for damaged, loose,
or missing parts or signs of wear at
least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and the
steel fuel door hinge, unless the
components are plastic. Applying
silicone grease on weatherstrips
with a clean cloth will make them
last longer, seal better, and not stick
or squeak. Underbody Maintenance At least twice a year, spring and fall,
use plain water to flush any
corrosive materials from the
underbody. Take care to thoroughly
clean any areas where mud and
other debris can collect.
Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water
can overcome the seals and
contaminate the fluid. Contaminated
fluid will decrease the life of the
transfer case and/or axles and
should be replaced.
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 Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting Airborne pollutants can fall upon
and attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See “ Finish Care ”
previously in this section.
Interior Care To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils.
Newspapers or dark garments can
transfer color to the vehicle ’ s
interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild
soap solution, immediately remove

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

Vehicle Care 305hand lotions, sunscreen, and insect
repellent from all interior surfaces or
permanent damage may result.
Use cleaners specifically designed
for the surfaces being cleaned to
prevent permanent damage. Apply
all cleaners directly to the cleaning
cloth. Do not spray cleaners on any
switches or controls. Remove
cleaners quickly.
Before using cleaners, read and
follow all safety instructions on the
label. While cleaning the interior,
open the doors and windows to get
proper ventilation.
To prevent damage, do not clean
the interior using the following
cleaners or techniques:
.
Never use a razor or any other
sharp object to remove soil from
any interior surface.
.
Never use a brush with stiff
bristles.
.
Never rub any surface
aggressively or with too much
pressure. .
Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners,
use approximately 20 drops per
3.8 L (1 gal) of water.
A concentrated soap solution will
create streaks and attract dirt.
Do not use solutions that contain
strong or caustic soap.
.
Do not heavily saturate the
upholstery when cleaning.
.
Do not use solvents or cleaners
containing solvents.
Interior Glass To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning with
plain water. CautionTo prevent scratching, never use
abrasive cleaners on automotive
glass. Abrasive cleaners or
aggressive cleaning may damage
the rear window defogger.
Cleaning the windshield with water
during the first three to six months
of ownership will reduce tendency
to fog.
Speaker Covers Vacuum around a speaker cover
gently, so that the speaker will not
be damaged. Clean spots with water
and mild soap.
Coated Moldings Coated moldings should be cleaned.
.
When lightly soiled, wipe with a
sponge or soft, lint-free cloth
dampened with water.
.
When heavily soiled, use warm
soapy water.

306 Vehicle Care Fabric/Carpet/Suede Start by vacuuming the surface
using a soft brush attachment. If a
rotating vacuum brush attachment is
being used, only use it on the floor
carpet. Before cleaning, gently
remove as much of the soil as
possible:
.
Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
.
For solid soils, remove as much
as possible prior to vacuuming.
To clean:
1. Saturate a clean, lint-free
colorfast cloth with water.
Microfiber cloth is
recommended to prevent lint
transfer to the fabric or carpet.
2. Remove excess moisture by
gently wringing until water does
not drip from the cleaning cloth.
3. Start on the outside edge of the
soil and gently rub toward the
center. Fold the cleaning cloth to a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the
soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely
removed, use a mild soap
solution followed only by plain
water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
After cleaning, use a paper towel to
blot excess moisture. Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays Use a microfiber cloth on high gloss
surfaces or vehicle displays. First,
use a soft bristle brush to remove
dirt that can scratch the surface.
Then gently clean by rubbing with a
microfiber cloth. Never use window
cleaners or solvents. Periodically
hand wash the microfiber cloth
separately, using mild soap. Do not
use bleach or fabric softener. Rinse
thoroughly and air dry before
next use.
CautionDo not attach a device with a
suction cup to the display. This
may cause damage and would
not be covered by the vehicle
warranty.
