climate control NISSAN MAXIMA 2000 A33 / 5.G Owners Manual

IAvoid holding the brake pedal down too
long or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
When towing a trailer, change oil in the
transmission more frequently.
See ªPeriodic maintenance schedulesº in
the ª9. Maintenanceº section.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
TreadwearTreadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions 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
measured under controlled conditions on
specified government test surfaces of asphaltand concrete. A tire marked C may have poor
traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.Temperature A, B and CTemperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.
