FUEL-FILLER CAP
The fuel-filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten,
turn the cap clockwise until ratcheting clicks
are heard.
WARNING
cGasoline is extremely flammable and highly
explosive under certain conditions. You
could be burned or seriously injured if it is
misused or mishandled. Always stop engine
and do not smoke or allow open flames or
sparks near the vehicle when refueling. c
Do not attempt to top off the fuel tank after
the fuel pump nozzle shuts off automati-
cally. Continued refueling may cause fuel
overflow, resulting in fuel spray and possi-
bly a fire.
c Use only an original equipment type fuel-
filler cap as a replacement. It has a built-in
safety valve needed for proper operation of
the fuel system and emission control sys-
tem. An incorrect cap can result in a serious
malfunction and possible injury. It could
also cause the malfunction indicator light to
come on.
c Never pour fuel into the throttle body to at-
tempt to start your vehicle.
c Do not fill a portable fuel container in the
vehicle or trailer. Static electricity can cause
an explosion of flammable liquid, vapor or
gas in any vehicle or trailer. To reduce the
risk of serious injury or death when filling
portable fuel containers:
± Always place the container on the ground when filling.
± Do not use electronic devices when filling.
± Keep the pump nozzle in contact with the container while you are filling it. ± Use only approved portable fuel contain-
ers for flammable liquid.
CAUTION
cIf fuel is spilled on the vehicle body, flush it
away with water to avoid paint damage.
c Insert the cap straight into the fuel-filler
tube, then tighten until the fuel-filler cap
clicks. Failure to tighten the fuel-filler cap
properly may cause the
malfunction
indicator light (MIL) to illuminate. If the
light illuminates because the fuel-
filler cap is loose or missing, tighten or in-
stall the cap and continue to drive the ve-
hicle. The
light should turn off after a
few driving trips. If the
light does not
turn off after a few driving trips, have the
vehicle inspected by an INFINITI retailer.
For additional information, see ªMalfunction
Indicator Light (MIL)º in the ª2. Instruments
and controlsº section.

cIf a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient 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, imme-
diately 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 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 dispens-
ing pumps to be identified by a small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. 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 can cause persistent,
heavy ªspark knockº. (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 spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or enginedamage. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is not a cause for con-
cern, because you get the greatest fuel benefit
when there is light spark knock for a short time
under heavy engine load.
CAUTION
c
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
c E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
c 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
percentage for that region.
