ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower amperage
rating than that specified on the fuse box cover.
This could damage the electrical system or
cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is pushed to the OFF or LOCK position and the head-
light switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery. 3. Remove the fuse/fusible link holder
cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is open
A, replace it with a
new fuse
B. Spare fuses are stored in the
passenger compartment fuse box.
6. If a new fuse also opens, have the elec- trical system checked and repaired by an
INFINITI retailer.
Fusible links
If any electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine INFINITI
parts.

●If 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 undesirable driveability problems such as
engine stalling or hard 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 (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit 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 above can cause per-
sistent, 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 mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to theengine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
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 specifi-
cally 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 identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

You may notify INFINITI by contacting our
Consumer Affairs Department, toll-free,
at 1-800-662-6200.A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due 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 emis-
sion 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/maintenance test readiness condi-
tion. Push the ignition switch to 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/Mtest condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
If the MIL indicates the vehicle is in a “not
ready” condition, drive the vehicle through the
following pattern to set the vehicle to the
“ready condition”. If you cannot or do not want
to perform the driving pattern, an INFINITI re-
tailer can conduct it for you.
WARNING
Always drive the vehicle in a safe and prudent
manner according to traffic conditions and
obey all traffic laws.
1. Start the engine. Allow the engine to idle
until the engine coolant temperature
gauge needle points between the C and H
(normal operating temperature).
2. Accelerate the vehicle to 55 MPH (88 km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 10 seconds.
3. Quickly depress the accelerator pedal for a moment, then drive the vehicle at a
speed of 53 to 60 MPH (86 to 96 km/h) for
at least 9 minutes.
4. Stop the vehicle. Leave the engine run- ning.
