Fusible linksGUID-85CCA4A5-CFBD-4923-A9D8-AF759D45C85CIf any electrical equipment does not
operate and the fuses are in good condi-
tion, check the fusible links. If any of these
fusible links are melted, replace only with
genuine INFINITI parts.
FUSES

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.

defect which could cause a crash or
could cause injury or death, you
should immediately inform Transport
Canada in addition to notifying
INFINITI.
If Transport Canada receives com-
plaints, it may open an investigation,
and if it finds that a safety defect
exists in a group of vehicles, it may
request that INFINITI conduct a recall
campaign. However, Transport Cana-
da cannot become involved in indivi-
dual problems between you, your
retailer, or INFINITI.

GUID-DE768414-DE66-4626-ABA5-95A2BBEEAA98Due to legal requirements in some states/
areas or provinces, your vehicle may be
required to be in what is called the
“ready
condition” for an Inspection/Maintenance
(I/M) test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
the vehicle may be reset to a “not ready
condition”. Before taking the I/M test,
check the vehicle’s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing.
