If NHTSA receives similar complaints, it may open an
investigation, and if it finds that a safety defect exists in
a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved in
individual problems between you, your authorized
dealer, and the manufacturer.
To contact NHTSA, you may either call the Auto Safety
Hotline toll free at 1–888–327–4236 (TTY: 1–800–424–
9153), or go to http://www.safercar.gov; or write to:
Administrator, NHTSA, 1200 New Jersey Avenue, SE.,
West Building, Washington, D.C. 20590. You can also
obtain other information about motor vehicle safety from
http://www.safercar.gov.In Canada
If you believe that your vehicle has a safety defect, you
should contact the Customer Service Department imme-
diately. Canadian customers who wish to report a safety
defect to the Canadian government should contact Trans-
port Canada, Motor Vehicle Defect Investigations and
Recalls at 1-800-333-0510 or go to

TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire’s manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger car tires must conform to Federal safety
requirements in addition to these grades.
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 one-half
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 departsignificantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These 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 perfor-
mance.
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.

Temperature Grades
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 repre-
sent 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, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENTSpecial design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained personnel.
The following must be observed during installation.
The positive power connection should be made directly to
the battery and fused as close to the battery as possible. The
negative power connection should be made to body sheet
metal adjacent to the negative battery connection. This
connection should not be fused.
Antennas for two-way radios should be mounted on the roof
or the rear area of the vehicle. Care should be used in
mounting antennas with magnet bases. Magnets may affect
the accuracy or operation of the compass on vehicles so
equipped.The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use only
fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to ensure
a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interference
between the communications equipment and the vehicle’s
electronic systems.
