O
DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts due
to lack of transmission lubrication.
O
For emergency towing procedures, see
“Towing recommended by INFINITI” in
the “6. In case of emergency” section of
this manual.
To tow a vehicle equipped with an auto-
matic transmission, an appropriate ve-
hicle dolly
MUST
be placed under the
towed vehicle’s drive wheels.
Always
follow the dolly manufacturer’s recom-
mendations when using their product.
DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rat-
ing 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 (1 1/2) times as well on
the government course as a tire graded
100. The relative performance of tires de-
pends upon the actual conditions of their
use, however, and may depart signifi-
cantly from the norm due to variations in
driving habits, service practices and dif-
ferences in road characteristics and cli-
mate.
Traction AA, A, B and 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 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 A, B and C
The temperature grades are A (the high-
est), B, and C, representing the tire’s re-
sistance 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 corre-
sponds to a level of performance which
all passenger car tires must meet under
the Federal Motor Safety Standard No.
