Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the
tire sidewall between tread
shoulder and maximum section
width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires
by treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply to
deep tread, winter-type snow
tires, space-saver, or temporaryuse spare tires, tires with nominal
rim diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger cars
and light trucks may vary
with respect to these grades,
they must also conform to
federal safety requirements and
additional General Motors
Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a
comparative rating based on
the wear rate of the tire when
tested under controlled
conditions on a speci ed
government test course.
For example, a tire graded 150
would wear one and a half (1.5)
times as well on the government
course as a tire graded 100.The relative performance of
tires depends upon the actual
conditions of their use, however,
and may depart signi cantly from
the norm due to variations in
driving habits, service practices,
and differences in road
characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest
to lowest, are AA, A, B, and C.
Those grades represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on speci ed
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.

Appearance Care
Interior Cleaning
The vehicle’s interior will continue
to look its best if it is cleaned often.
Although not always visible, dust
and dirt can accumulate on the
upholstery. Dirt can damage carpet,
fabric, leather, and plastic surfaces.
Regular vacuuming is recommended
to remove particles from the
upholstery. It is important to keep
the upholstery from becoming and
remaining heavily soiled. Soils
should be removed as quickly as
possible. The vehicle’s interior may
experience extremes of heat that
could cause stains to set rapidly.
Lighter colored interiors may
require more frequent cleaning.
Use care because newspapers and
garments that transfer color to home
furnishings may also transfer color to
the vehicle’s interior.When cleaning the vehicle’s interior,
only use cleaners speci cally
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only on
glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the cleaning
cloth.
Notice:Using abrasive cleaners
when cleaning glass surfaces
on the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.Many cleaners contain solvents that
may become concentrated in the
vehicle’s breathing space. Before
using cleaners, read and adhere to
all safety instructions on the label.
While cleaning the vehicle’s interior,
maintain adequate ventilation by
opening the vehicle’s doors and
windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from the
vehicle’s upholstery and clean the
vehicle’s glass can be obtained from
your dealer/retailer.

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 6-13.
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.
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 5-75.
