cified 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 straightahead braking traction tests,
and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

& 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 Standards 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.

Reporting safety defects
(U.S.A.)
If you believe that your vehicle has
a defect which could cause a
crash or could cause injury or
death, you should immediately inform the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Subaru of
America, Inc.
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 dealer, or Subaru of
America, Inc. To contact NHTSA,
you may call the Vehicle Safety
Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
