Traction Control INFINITI QX30 2018 User Guide

drive at a reduced speed, otherwise, your
vehicle may be damaged and/or vehicle
handling and performance may be ad-
versely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to re-
move ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snow-
drifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
•Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or sanded.
•Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
•Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
•Allow greater following distances on
slippery roads.
•Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
•Do not use cruise control on slippery
roads.
•Snow can trap dangerous exhaust gas
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must con-
form to federal safety requirements in addi-
tion 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 rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
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 as-
phalt and concrete. A tire marked C may have
poor traction performance.
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 A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissi-
pate heat when tested under controlled con-
ditions 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 Standard No.
109. Grades B and A represent higher levelsof performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat build-up and possible tire
failure.
