Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum selection width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the Unites 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 temporary use
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.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and a half (1
1⁄2) 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 significantly 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 specified
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
332
Temperature — A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel
than the minimum required by law.
Warning:The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you the
longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing
will not be necessary on a regular basis. However,
if you notice unusual tire wear or your vehicle
pulling to one side or the other, the alignment may
need to be checked. If you notice your vehicle
vibrating when driving on a smooth road, your tires
and wheels may need to be rebalanced. See your
dealer/retailer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel leaks air,
replace it (except some aluminum wheels,
which can sometimes be repaired). See your
dealer/retailer if any of these conditions exist.
Your dealer/retailer will know the kind of wheel
you need.
333
Tire Chains
Notice: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.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the accelerator pedal and grip the steering wheel
firmly. Steer to maintain lane position, and then
gently brake to a stop well out of the traffic lane.A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes flat, the next part shows how to use the
jacking equipment to change a flat tire safely.

Customer Satisfaction Procedure
Your satisfaction and goodwill are important
to your dealer and to Chevrolet. Normally, any
concerns with the sales transaction or the

however, despite the best intentions of all
concerned, misunderstandings can occur. If your
concern has not been resolved to your
satisfaction, the following steps should be taken:
STEP ONE:Discuss your concern with a member
of dealership management. Normally, concerns
can be quickly resolved at that level. If the matter
has already been reviewed with the sales,
service, or parts manager, contact the owner of
the dealership or the general manager.STEP TWO:If after contacting a member of
dealership management, it appears your concern
cannot be resolved by the dealership without
further help, in the U.S., contact the Chevrolet

Transportation Options
Warranty service can generally be completed
while you wait. However, if you are unable to wait,
GM helps to minimize your inconvenience by
providing several transportation options.
Depending on the circumstances, your dealer can
offer you one of the following:
Shuttle Service
Shuttle service is the preferred means of offering
Courtesy Transportation and participating
dealers can provide you with shuttle service to get
you to your destination with minimal interruption
of your daily schedule. This includes one-way
or round trip shuttle service within reasonable time
and distance parameters for the dealer’s area.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
and public transportation is used as ‘shuttle
service,’ the reimbursement is limited to the
associated shuttle allowance and must be
supported by original receipts. In addition, for U.S.customers, should you arrange transportation
through a friend or relative, limited reimbursement
for reasonable fuel expenses may be available.
Claim amounts should reflect actual costs and be
supported by original receipts.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a
courtesy rental vehicle or reimburse you for
a rental vehicle that you obtain if your vehicle is
kept for an overnight warranty repair. Rental
reimbursement will be limited and must be
supported by original receipts. This requires that
you sign and complete a rental agreement
and meet state/provincial, local, and rental vehicle
provider requirements. Requirements vary and
may include minimum age requirements, insurance
coverage, credit card, etc. You are responsible
for fuel usage charges and may also be
responsible for taxes, levies, usage fees,
excessive mileage, or rental usage beyond the
completion of the repair.
Generally it is not possible to provide a like-vehicle
as a courtesy rental.

Collision Damage Repair
If your vehicle is involved in a collision and it is

technician using the proper equipment and
quality replacement parts. Poorly performed
collision repairs diminish your vehicle’s resale
value, and safety performance can be
compromised in subsequent collisions.
