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 re-
commended for unleaded gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 15% oxygenate.
. 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 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 vehi-
cle 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-oxyge-
nate 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 identi-
fied 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. government regulations require fuel
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMTcontent, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. 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,
it is recommended you have an INFINITI
retailer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn

10-24Technical and consumer information
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 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 depres-
sing 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 ac-
quired 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 re-
tailer, other parties, such as law enforce-
ment, that have the special equipment, 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.Genuine INFINITI Service Manual for this
model year and prior can be purchased. A
genuine INFINITI Service Manual is the best
source of service and repair information for
your vehicle. This manual is the same one
used by the factory-trained technicians
working at INFINITI retailers. Genuine
INFINITI Owner’s Manuals can also be
purchased.
