The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
CAUTION
When adding or replacing the coolant,
be sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized water/
distilled water. The use of other types of
coolant solutions may damage your en-
gine cooling system.Outside tempera-

CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level, add coolant to the MAX
level. If the reservoir tank is empty, check the
coolant level in the radiatorwhen the engine
is cold.If there is insufficient coolant in the
radiator, fill the radiator with coolant up to the
filler opening and also add it to the reservoir
tank up to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH
(56 km/h).
IIf the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
ITrailer towing requires more fuel than nor-
mal circumstances.
IAvoid towing a trailer for the first 500 miles
(800 km).
IHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule.
When towing a trailer, change oil in the
transmission more frequently. See the
Maintenance Schedule.UNIFORM TIRE QUALITY
GRADINGDOT (Department of Transportation) Quality
Grades: All passenger car tire 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 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 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.Technical and consumer information
