Additional information
NOTE FOR ENGINE COOLANT *:
(1) First replacement interval is 105,000
miles (168,000 km) or 84 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(2) Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50%
antifreeze and 50% demineralized or
distilled water. Mixing any other type of
coolant or the use of non-distilled water
may reduce the life expectancy of the
factory fill coolant.
* Maintenance items and intervals with “ *
” are recommended by INFINITI for
reliable vehicle operation. The owner need
not perform such maintenance in order to
maintain the emission warranty or
manufacturer recall liability. Other
maintenance items and intervals are
required.
NOTE FOR SPARK PLUGS:
(1) Replace every 105,000 miles
(168,000 km)
(2) Replace spark plug when the plug gap
exceeds 0.045 in (1.25 mm) even if within
specified replacement mileage.

FUEL RECOMMENDATION
Use unleaded premium gasoline with an oc-
tane 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 rat-
ing of at least 87 AKI number (Research oc-
tane 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.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
• Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
• Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst. •
Do not use a fuel containing more than
15% ethanol in your vehicle. Your vehicle
is not designed to run on a fuel contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the INFINITI New Vehicle Limited
Warranty.
Technical and consumer information10-3

•Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect ve-
hicle performance and vehicle emissions.
Not all fuel dispensers are labeled to in-
dicate MMT content, so you may have to
consult your gasoline retailer for more
details. Note that Federal and California
laws prohibit the use of MMT in refor-
mulated 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.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers de-
veloped this specification to improve emis-
sion control system and vehicle performance.
Ask your service station manager if the gaso-
line meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated
gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
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 recom-
mended for unleaded gasoline.
• If an oxygenate-blend other than metha-
nol blend is used, it should contain no more
than 15% oxygenate. •
If a methanol blend is used, it should con-
tain no more than 5% methanol (methyl
alcohol, wood alcohol). It should also con-
tain a suitable amount of appropriate co-
solvents and corrosion inhibitors. If not
properly formulated with appropriate co-
solvents and corrosion inhibitors, such
methanol blends may cause fuel system
damage and/or vehicle performance prob-
lems. 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
stalling and difficult 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 refuel-
ing. Gasoline containing oxygenates can
cause paint damage.
