Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace the drive belts if found dam-
aged.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause more rapid clogging
of the element. Consequently, the element
may have to be replaced more frequently.

be made with a tachometer to ensure
accuracy.
Vapor linesCheck vapor lines and connec-
tions for failure or looseness. If leaks are
found, replace them.
Fuel linesCheck the fuel hoses, pipingand connections for leaks, looseness or
deterioration. Replace any parts if they are
damaged.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Drain and flush the cool-
ing system.
Engine oil & oil filter*Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe
driving conditions, they may have to be
replaced more frequently.
Spark plugs*Replace with new plugs hav-
ing the correct heat range.
Intake & exhaust valve clearanceCheck
and adjust the valve clearance.
Chassis and body maintenance
Brake lines & cablesCheck the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and

FUEL RECOMMENDATION
All models are designed to operate on
unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index)
(Research octane number 91).
CAUTION
Using a fuel other than that specified
could adversely affect the emission
control devices and systems, and could
also affect the warranty coverage.
Under no circumstances should a
leaded gasoline be used, since this will
damage the three way catalyst.
Reformulated Gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use refor-
mulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising theirpresence. Nissan does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your NISSAN
cannot be readily determined. If in doubt,
ask your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle performance
problems and/or fuel system damage.
cThe fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
cIf an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
cIf a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system dam-
age and/or vehicle performance prob-lems. At this time, sufficient data is
not available to ensure that all metha-
nol blends are suitable for use in Nis-
san vehicles.
If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially. Many
of these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with

When planning to travel in another coun-
try,you should first find out if the fuel
available is suitable for your vehicle's en-
gine.
Using fuel with too low an octane/cetane
rating may cause engine damage. All gaso-
line vehicles must be operated with un-
leaded engine gasoline. Therefore, avoid
taking your vehicle to areas where appropri-
ate fuel is not available.
When transferring the registration of
your vehicle to another country, state,
province or district,it may be necessary to
modify the vehicle to meet local laws and
regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications
may differ.
When any vehicle is to be taken into
another country, state, province or dis-
trict and registered, its modifications,
transportation, and registration are the
responsibility of the user. NISSAN is not
responsible for any inconvenience that
may result.
VEHICLE IDENTIFICATION NUM-
BER PLATE
The vehicle identification number plate is
attached to the top of the instrument panel
on the driver's side. This number is the
identification for your vehicle and is used in
the vehicle registration.

re-weigh your vehicle to determine if
either GVWR or GAWR for your vehicle
is exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
Loading Tips
cThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S.
Certification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
CAUTION
cProperly secure all cargo to help
prevent it from sliding or shifting. In
a sudden stop or collision, unse-
cured cargo could cause personal
injury.
cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWRs. If you do,
parts on your vehicle can break, or it
can change the way your vehicle
handles. This could result in loss of
control and cause personal injury.cOverloading can shorten the life of
your vehicle. Failures caused by
overloading are not covered by your
warranty.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer places ad-
ditional loads on your vehicle's engine, drive
train, steering, braking and other systems.

able from your NISSAN dealer. This guide
includes information on trailer towing ability
and the special equipment required for
proper towing.

cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
c
If the engine temperature coolant rises to
an extremely high temperature when the
air conditioning system is on, turn off the
air conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and set-
ting the temperature control to the HOT
position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.cCrosswinds and rough roads adversely
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 imme-
diately (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 fifth gear (manual transmission)
or overdrive (automatic transmission).
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 the oil in
the transmission more frequently.
See the Maintenance Schedule.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments 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 controlled con-
ditions, on specified government test sur-
faces 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
