FUEL RECOMMENDATION
INFINITI recommends the use of premium un-
leaded gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96) . If unleaded premium gaso-
line is not available, you may use unleaded regular
gasoline with an octane rating of at least 87 AKI
number (Research octane number 91) , but you
may notice a decrease in performance.
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 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 specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. INFINITI
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates 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 other than metha-
nol 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 (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 INFINITI vehicles.
If any driveability problems such as engine stall-
ing and difficult 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 refu-
eling. Gasoline containing oxygenates can
cause paint damage.

This vehicle is equipped with an Event Data Re-
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in understand-
ing 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 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 understand-
ing 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 investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer and INFINITI dealer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess 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 per-
mitted by law.
A genuine INFINITI Service Manual is the best
source of service and repair information for your
vehicle. Filled with wiring diagrams, illustrations
and step-by-step diagnostic and adjustment pro-
cedures, this manual is the same one used by the
factory-trained technicians working at INFINITI
dealerships. Also available are genuine INFINITI
Owner’s Manuals, and genuine INFINITI Service
and Owner’s Manuals for older INFINITI models.
