the tire(s) should be replaced.

The original tires have a built-in
tread wear indicator. When the
wear indicators are visible, the
tire(s) should be replaced.

Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.

Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, contact a
NISSAN dealer.

For additional information re-
garding tires, refer to “Tire
Safety Information” in the War-
ranty Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING

The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.

If the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offsetcould cause premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to “Wheels and
Tires” in the “Technical and con-
sumer information” section of this
manual for wheel offset dimensions.

Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.

The use of retread tire is not recom-
mended.

For additional information regarding
tires, refer to “Tire Safety Informa-
tion” in the Warranty Information
Booklet.
Wheel balanceUnbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can

get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires, refer to
“Tire Safety Information” in the Warranty Infor-
mation Booklet.Care of wheels
Wash the wheels when washing the vehicle
to maintain their appearance.

Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.

Do not use abrasive cleaners when washing
the wheels.

Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.

NISSAN recommends waxing the road wheel
sidewalls to protect against road salt in areas
where it is used during winter.

FUEL RECOMMENDATIONUse unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (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 cover-
age.

Under no circumstances should a
leaded gasoline be used, since this
will damage the three-way catalyst.

Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run
on E-85 fuel. Using E-85 fuel can
damage the fuel system components
and is not covered by the NISSAN
vehicle limited warranty.Gasoline specificationsNISSAN recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-cations where it is available. Many of the auto-
mobile manufacturers developed this specifica-
tion to improve the emission control system and
vehicle performance. Ask your service station
manager if the gasoline meets the WWFC
specifications.
Reformulated gasolineSome fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility 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.

The fuel should be unleaded and have
an octane rating no lower than thatrecommended for unleaded gasoline.

If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are
suitable for use in NISSAN vehicles.
If any undesirable driveability problems such as
engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.

E-85 fuelE-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square, or-
ange and black label with the common abbre-
viation or the appropriate percentage for that
region.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knockwhile holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life and
performance. NISSAN recommends the use of a
low friction oil (energy conserving oil) in order to
improve fuel economy and conserve energy. Oils
which do not have the specified quality labelshould not be used as they could cause engine
damage.
Only those engine oils with the American Petro-
leum Institute (API) certification mark on the front
of the container should be used. This type of oil
supersedes the existing API SG, SH, or SJ and
Energy ConservingI&IIcategories.
If you cannot find engine oil with the API certifi-
cation mark, use an API grade SG, Energy
Conserving II or API grade SH, SJ or SL, Energy
conserving oil. An oil with a single designation
SG or SH, or in combination with other catego-
ries (for example, SG/CC or SG/CD) may also
be used if one with the API certification markcannot be found. An ILSAC grade, GF-II or
GF-III oil can also be used.
NISSAN recommends mineral based oils. These
oils must however, meet the API quality and SAE
viscosity ratings specified for your vehicle.
Oil additivesNISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.Oil viscosityThe engine oil viscosity or thickness changes
with temperature. Because of this, it is important
that the engine oil viscosity be selected based
on the temperatures at which the vehicle will be
operated before the next oil change. The recom-
mended SAE viscosity number chart shows the
recommended oil viscosities for the expected
ambient temperatures. Choosing an oil viscosity
other than that recommended could cause seri-
ous engine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-quality
genuine NISSAN oil filter. When replacing, use
STI0367A
Technical and consumer information

06.4.14/T30-J/V5.0


the genuine oil filter or its equivalent for the
reason described in change intervals.Change intervalsThe oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than the
specified quality, or oil and filter change intervals
longer than recommended could reduce engine
life. Damage to engines caused by improper
maintenance or use of incorrect oil and filter
quality and/or viscosity is not covered by the
new NISSAN vehicle warranties.
Your engine was filled with a high quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle. Operation under
the following conditions may require more fre-
quent oil and filter changes.

repeated short distance driving at cold out-
side temperatures,

driving in dusty conditions,

extensive idling,

towing a trailer,

stop and go “rush hour” traffic,

aggressive driving.
RECOMMENDED SAE VISCOSITY
NUMBERSAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30,
10W-40 viscosity oil may be used if the
ambient temperature is above −18°C (0°F).
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
NISSAN A/C System Oil Type S or the
exact equivalents.
CAUTION
The use of any other refrigerant or lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner sys-
tem components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling of
any refrigerant during automotive air condition-
ing system service. Your NISSAN dealer has the
trained technicians and equipment needed to
recover and recycle your air conditioning system
refrigerant.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 805 km
(500 miles).

Have your vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.

Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

Do not use cruise control while towing a
trailer.

Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 80
km (50 miles) of travel and at every break.

When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, the transmission
oil/fluid should be changed more fre-
quently. For additional information, see
the “8. Maintenance and do-it-yourself”
section earlier in this manual.
FLAT TOWINGTowing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a ve-hicle behind a recreational vehicle, such as a
motor home.
CAUTION

Failure to follow these guidelines
can result in severe transmission
damage.

Whenever flat towing your vehicle,
always tow forward, never backward.

DO NOT tow any automatic transmis-
sion vehicle with all four wheels on
the ground (flat towing). Doing so
WILL DAMAGE internal transmission
parts due to lack of transmission lu-
brication.

For emergency towing procedures re-
fer to “Towing Recommended by
NISSAN” in the “6. In case of emer-
gency” section of this manual.Automatic transmissionTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST

recommendations when using their product.Manual transmissionAll mode 4WD (four-wheel drive) models:
Never tow All mode 4WD models with any of the
wheels on the ground.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
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm 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 speci-
fied indoor laboratory test wheel. Sustained high
temperature can cause tire material to degener-
ate, reducing tire life. Excessive temperatures
can lead to sudden tire failure. Grade C corre-
sponds to a performance level which all passen-
ger 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 re-
quired by law.
