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 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 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.
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.

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit on/off
switch (B) is in the O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 3-46for more
information.
Do not slam door or close window on the
compressor accessory plug cord.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-38.
6. Start the vehicle. SeeStarting the Engine on
page 2-29for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
In ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in ator instructions, and
in ate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Push the On/Off switch to the I (on) position.
The sealant and compressor kit will inject sealant and
air into the tire. Sealant may leak from the puncture
until the vehicle is driven and the hole has sealed.

3. Pull the air compressor in ator hose from the
sealant canister.
4. Push the air compressor in ator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-46for more information.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-38.
6. Start the vehicle. SeeStarting the Engine on
page 2-29for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
In ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in ator instructions, and
in ate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Move the sealant and compressor kit switch to
the I (on) position.
8. In ate the tire up to the recommended in ation
pressure using the air pressure gage on the top
of the unit.
The pressure gage read high while the compressor
is running. Turn the compressor off to get an
accurate reading.

The underhood fuse block is located in the front of the
engine compartment on the passenger’s side of the
vehicle. SeeEngine Compartment Overview on
page 5-11for more information on location and removal
procedure for the front compartment underhood
sights shields.
To access the fuses, push in the tabs located on each
side of the fuse block cover, then lift the cover off.
Notice:Spilling liquid on any electrical components
on your vehicle may damage it. Always keep the
covers on any electrical component.
