Subaru Forester: Uniform tire quality grading standards / 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 straightahead
braking traction tests,
and does not include acceleration,
cornering, hydroplaning,
or peak traction characteristics.
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...
Other information:
So that it can be used safely and comfortably,
the Auto Start Stop system is
designed to constantly monitor the vehicle
conditions as well as the environment
inside and outside the vehicle in addition
to driver operations, and to provide various
warnings to the driver via the warning light
and/or indicator light illuminating or flashing
and a buzzer sounding...
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt...
