AUTOMATIC TRANSMISSIONTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.MANUAL TRANSMISSIONAlways tow with the manual transmission in
Neutral.
After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause damage
to internal transmission parts.DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
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
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-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 and CThe 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 mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking trac-
tion tests, and does not include accel-
eration, cornering, hydroplaning, or
peak traction characteristics.Temperature A, B and CThe 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. Sus-
tained 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 Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
