FUEL INFORMATION
VQ37VHR engine
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96) .
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rating
of at least 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
possible.
. Avoid full throttle driving and abrupt accel-
eration.
Use unleaded premium gasoline for max-
imum vehicle performance.
CAUTION
. Using a fuel other than that speci-
fied could adversely affect the emis-
sion control system, and may also
affect warranty coverage.
. Under no circumstances should a
leaded gasoline be used, because this will damage the three-way cat-
alyst.
. Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed
to run on E-15 or E-85 fuel. Using E-
15 or E-85 fuel in a vehicle not
specifically designed for E-15 or E-
85 fuel can adversely affect the
emission control devices and sys-
tems of the vehicle. Damage caused
by such fuel is not covered by the
NISSAN new vehicle limited war-
ranty.
. U.S. government regulations require
ethanol dispensing pumps to be
identified by a small, square, orange
and black label with the common
abbreviation or the appropriate per-
centage for that region.
Gasoline specifications
NISSAN recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) speci-
fications where it is available. Many of the
automobile manufacturers developed this spe-
cification to improve emission system and
vehicle performance. Ask your service station
manager if the gasoline meets the World-Wide
Fuel Charter (WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated 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 oxygenates
Some 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
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.
.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
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
.E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the NISSAN New
Vehicle Limited Warranty.
. If 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 damage
and/or vehicle 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 or hard hot starting are experi-
enced after using oxygenate-blend fuels, im-
mediately 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 oxygenates
can cause paint damage.E-15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-
15 fuel. Do not use E-15 in your vehicle. U.S.
government regulations require fuel ethanol
dispensing pumps to be identified with small,
square, orange and black label with the common
abbreviation or the appropriate percentage for
that region.
E-85 fuel
E-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,
orange and black label with the common
abbreviation or the appropriate percentage for
that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (Example: fuel injector
cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
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 tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, 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 knock while holding a steady speed
on level roads, have a NISSAN 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
encountered, have your vehicle checked at a
NISSAN dealer or other competent service
facility.
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 RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance, see
“Capacities and recommended fluids/lubricants”
(P.9-2) . 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
certification 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 additives
NISSAN 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 viscosity
The 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 filter
Your new vehicle is equipped with a high-quality
genuine NISSAN oil filter. When replacing, use
the genuine oil filter or its equivalent for the
reason described in change intervals.
Change intervals
The 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

SPECIFICATIONS
If you plan to travel in another country,you
should first find out if the fuel available is suitable
for your vehicle’s engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate 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 district
and registered, its modifications, transpor-
tation, and registration are the responsi-
bility of the user. NISSAN is not
responsible for any inconvenience that
may result.

EMISSION CONTROL INFORMATION
LABEL
The emission control information label is at-
tached as shown.
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle 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 back-
ward.
. DO NOT tow any automatic trans-
mission vehicle with all four wheels
on the ground (flat towing) . Doing
so WILL DAMAGE internal transmis-
sion parts due to lack of transmis-
sion lubrication.
. For emergency towing procedures
refer to “Towing recommended by
NISSAN (except for NISMO mod-
els)” (P.6-19) of this manual.
AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly MUST
be placed under the towed vehicle’s drive
wheels. Always follow the dolly manufacturer’s
recommendations when using their product.
MANUAL TRANSMISSION
. Always tow with the manual transmission in
Neutral.
. Your vehicle speed should never exceed 70
MPH (112 km/h) when flat towing your
vehicle.
. After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause
damage to the transmission’s internal parts. 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 ATREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government 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 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 char-
acteristics and climate.
TRACTION AA, A, B AND C
The 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
measured under controlled conditions on spe-
cified government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.

UNIFORM TIRE QUALITY GRADING
9-24Technical and consumer information
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be
required to be in what is called the “ready
condition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s inspection/
maintenance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds and
then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
Contact a NISSAN dealer to set “ready condi-
tion” or to prepare the vehicle for testing.This vehicle is equipped with an Event Data
Recorder (EDR) . The main purpose of an EDR is
to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed to
record such data as:
.
How various systems in your vehicle were
operating;
. Whether or not the driver and passenger
safety belts were buckled/fastened;
. How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE: EDR data are
recorded by your vehicle only if a nontrivial
crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no
personal data (e.g. name, gender, age and crash
location) are recorded. However, other parties,
such as law enforcement, could combine the
EDR data with the type of personally identifying data routinely acquired during a crash investiga-
tion.
To read data recorded by an EDR, special
equipment is required and access to the vehicle
or the EDR is needed. In addition to the vehicle
manufacturer and NISSAN dealer, other parties,
such as law enforcement, that have the special
equipment, can read the information if they have
access to the vehicle or the EDR.
