more hours, or driven less than 1 mile (1.6
km). COLD tire pressures are shown on the
tire placard affixed to the glove box door.
CAUTION
The vehicle weight capacity is indicated
on the tire placard. Do not load your
vehicle beyond this capacity. Overload-
ing your vehicle may result in reduced tire
life, unsafe operating conditions due to
premature tire failure, or unfavorable han-
dling characteristics and could also lead
to a serious accident. Loading beyond the
specified capacity may also result in fail-
ure of other vehicle components.
Before taking a long trip, or whenever
you have loaded your vehicle heavily,
use a tire pressure gauge to ensure that
the tire pressure is at the specified level.
CAUTION
Do not drive your vehicle over 85 MPH
(140 km/h) unless it is equipped with
high speed capability tires. Driving
faster than 85 MPH (140 km/h) may
result in tire failure, loss of control and
possible injury.
Types of tires
CAUTION
When changing or replacing tires, be sure
all four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. Your NISSAN dealer may be
able to help you with information about
tire type, size, speed rating and availabil-
ity. Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
All season tires
NISSAN specifies All Season tires to pro-
vide good performance all year, including
snowy and icy road conditions. All Season
Tires are identified by ``ALL SEASON''
and/or ``M&S'' on the tire sidewall. Snow
tires have better snow traction than All
Season tires and may be more appropriate
in some areas.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load ratingto the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some states
and provinces prohibit their use. Check lo-
cal, state and provincial laws before install-
ing studded tires. Skid and traction capabili-
ties of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE Class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight

affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and immedi-
ately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use overdrive.
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change fluid in the
transmission more frequently.
See the Maintenance schedule.Department of Transportation (DOT) Qual-
ity Grades: All passenger car tires must
conform to Federal Safety Requirements in
addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment 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 depends on actual
driving conditions, and may vary signifi-
cantly from the norm, due to variations in
driving habits, service practices and differ-
ences in road characteristics and climate.
Traction A, B and C
Traction grades are A (the highest), B and
C. They represent a tire's ability to stop on
wet pavement as measured under con-
trolled conditions, on specified government
test surfaces of asphalt and concrete. A tire
marked with a C may have poor traction
performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight line
braking traction tests and does not
include cornering (turning) traction.
Temperature A, B and C
Temperature 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 condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material 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 perfor-
mance on laboratory test wheels than the
minimum required by law.
