CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS

9-4Technical and consumer information
FUEL RECOMMENDATIONGUID-C4EBF802-DA64-447B-B779-C109AAFB1C2E
VQ37VHR engineGUID-87613AFC-C9C8-49FC-A77B-8754508A3C72Use 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 possible.
. Avoid full throttle driving and abrupt
acceleration.
However, for maximum vehicle perfor-
mance, the use of unleaded premium
gasoline is recommended.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage. .
Under no circumstances should a leaded
gasoline be used, because 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 INFINITI vehicle limited warranty.
Gasoline specificationsGUID-DC5EBB8E-4309-49CA-B420-EC02637A87FBINFINITI recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many
of the automobile manufacturers devel-
oped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gaso-
line meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasolineGUID-219272A9-E868-427B-AE5E-D1FC55A1EF42Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when available.
Gasoline containing oxygenatesGUID-485DABCD-B3C9-4464-A7DA-50A021D72D80Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
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%.)
. 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 INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced 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 oxygenates
can cause paint damage.
E-85 fuelGUID-E80ADFC3-9E29-4E93-9DFA-C473E4854F8AE-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. government
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 additivesGUID-511317C7-4DF3-4C2C-A81B-F6771C931D09INFINITI 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 tipsGUID-FF7F51AB-6CE5-4893-AEC1-750B862FF0AFUsing 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 an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for
which INFINITI 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 an INFINITI retailer
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.CAUTION
.
Your vehicle is not designed to run on E-
85 fuel. Using E-85 fuel in a vehicle not
specifically designed for E-85 fuel can
damage fuel system components and is
not covered by the INFINITI new vehicle
limited warranty.
. E-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline.
. U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.

COMMENDATION
GUID-058FA41E-D16E-49C1-B0F1-1263C55FFFD2
Selecting the correct oilGUID-9C2E08EF-024B-4ED8-82D3-E209D6D2E59EIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). INFINITI 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) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity 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 additivesGUID-9E75C8D6-814E-4BD1-BCD1-16235F7FBEB1INFINITI 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 viscosityGUID-8F8E9479-970D-4961-A158-B90660C9C234The 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 filterGUID-9B993B66-0673-49BD-8C4D-409281450A66Your 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 intervalsGUID-F52EE258-6ADA-49F3-A839-FCF212BBD17BThe 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 INFINITI vehicle limited warran-
ties.
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
outside temperatures,
. driving in dusty conditions,
. extensive idling,
. stop and go “rush hour”traffic,
Refer to the “INFINITI Service and Main-
tenance Guide” for the maintenance sche-
dule.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
GUID-DA065BA2-96F6-4EA0-A393-35BEA4197869The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant 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 lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.

GUID-4DCAB315-AC66-4A49-A484-5C2927B4F2E4DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARGUID-61A676A7-9B91-4A79-A32F-E8D628C55791The 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, how-
ever, 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 CGUID-BA7990B4-C685-4A1D-A234-3E4A1FA8B404The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND CGUID-7A8C8273-BED1-4908-B544-D79557E7C502The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to suddentire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading,
either separately or in combination, can
cause heat build-up and possible tire failure.

9-24Technical and consumer information
GUID-9023DE11-7F99-4014-8B76-63304941B6C9This 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 performed. 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 passen-
ger safety belts were buckled/fas-
tened;
. 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
understanding 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 loca-
tion) 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 investigation.
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 INFINITI
retailer, other parties, such as law en-
forcement, that have the special equip-
ment, can read the information if they
have access to the vehicle or the EDR. EDR
data will only be accessed with the
consent of the vehicle owner or lessee or
as otherwise required or permitted by law.GUID-19D5C887-4796-4FEC-856C-8B97CA64084BGenuine INFINITI Service Manual for this
model and prior models can be purchased.
