2. Wear indicator location markTire wear and damage
WARNING

Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,the tire(s) should be replaced.

The original tires have built-in
tread wear indicators. 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 “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See “Specifications” in the “9. Tech-
nical and consumer information” section for rec-
ommended types and sizes of tires and wheels.
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 off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
possibly degraded vehicle handling
characteristics and/or interference
with the brake discs/drums. Such in-
terference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear.

When a spare tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on after the 1 minute. Contact your
NISSAN dealer as soon as possible
for tire replacement and/or system
resetting.

Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.

Do not install a deformed wheel or
tire even if it has been repaired. Suchwheels 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 “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) 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 performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information 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 that the road wheels
be waxed to protect against road salt in areas
where it is used during winter.Spare tire (T-type spare tire)Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
CAUTION

The T-type spare tire should be used
for emergency use only. It should be
replaced by the standard tire at the
first opportunity.

FUEL RECOMMENDATIONUse unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:

Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.

Avoid full throttle driving and abrupt accelera-
tion.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION

Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
the warranty coverage.
Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way cata-
lyst.

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 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 that
recommended 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-
Technical and consumer information

07.2.9/Z33-D/V5.0


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
solvents or similar ingredients that can be harm-
ful 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 above stated
octane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, have your dealer correct the
condition. 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 aNISSAN 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.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct grade,
quality and viscosity engine oil to ensure satis-
factory engine life and performance. See “Ca-
pacities and recommended fuel/lubricants” ear-
lier in this section. NISSAN recommends the use
of an energy conserving oil in order to improve
fuel economy.Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API certifi-
cation mark on the front of the container. Oils
which do not have the specified quality label
should not be used as they could cause engine
damage.
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. Choosing
an oil viscosity other than that recommended
could cause serious engine damage.Selecting the correct oil filterYour new NISSAN vehicle is equipped with a
high-quality genuine NISSAN oil filter. When
replacing, use a genuine NISSAN 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 limited 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 frequent 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 commuting
Refer to the “NISSAN Service and Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioner system in your 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 conditioner
system service. A NISSAN dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.Contact a NISSAN dealer when servicing your
air conditioner system.

trol to high and setting the temperature con-
trol to the HOT position.

Trailer towing consumes more fuel than nor-
mal circumstances.

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

Have a 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.

To maintain engine braking efficiency and
electrical charging performance, do not use
6th gear (manual transmission) or 5th posi-
tion (automatic transmission).

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 50
miles (80 km) 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, change transmis-
sion oil more frequently. For additional
information, see the “8. Maintenance and
do-it-yourself” section.Towing 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,
refer to “Towing recommended by
NISSAN” in the “6. In case of emer-
gency” section of this manual.FLAT TOWINGTechnical and consumer information
