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 tothe OFF or LOCK position and the
headlight switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery and the fuse/
fusible link holder.
3. Remove the fuse/fusible link holder
cover.
4. Remove the fuse with the fuse puller.
SDI1754
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 electrical system checked and repaired
by an INFINITI retailer.
The holder
*1also contains the fuses. For
checking and/or replacing, see an INFINITI
retailer.
Fusible linksY51D-V-E01-3E721E86-CD62-4D57-8D17-0637DAF969EFIf 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

15%.)
. E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the INFINITI New
Vehicle Limited Warranty.
. 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 appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
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-15 fuelGUID-55AA3E5D-B4B7-4387-A6C1-514DB0C16738E-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 identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
E-85 fuelY51D-V-E01-019B5956-3FF3-4BF6-B50B-B0FD9BE1DD27E-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 additivesY51D-V-E01-0241A1D6-50DD-4735-AB1B-1BF6D3FF4840INFINITI 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 tipsY51D-V-E01-0C94128B-44FC-407D-B5D4-1374AB611F20Using 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.

Selecting the correct oilY51D-V-E01-7FE27830-3B20-44C8-B50F-C4B29604F170It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). INFINITI recommends
the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additivesY51D-V-E01-66B343FB-CACE-4D63-BB72-E04A44C2B684INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.

Oil which may contain foreign matter or
has been previously used should not be
used.
Oil viscosityY51D-V-E01-1D29E55F-7AAE-49F2-9464-345D50DC853BThe engine oil viscosity or thickness
changes with temperature. Because of this,
it is important that the engine oil viscosity
be selected based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil
viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filterY51D-V-E01-5A15E0C7-81B2-4108-AB38-F9762761AFB2Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine oil filter or its
equivalent for the reason described in
change intervals.
Change intervalsY51D-V-E01-98B578A3-E1FB-47E1-B0D2-3E275400406CThe oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Oil and
filter other than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil andfilter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle. Operation under the
following conditions may require more
frequent oil and filter changes.

COMMENDATIONS
Y51D-V-E01-CDCFAB3E-830C-4475-8A79-A638F5620A17The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.

you should first find out if the fuel
available is suitable for your vehicle’s
engine.
Using fuel with too low an octane rating
may cause engine damage. All gasoline
vehicles must be operated with unleaded
gasoline. Therefore, avoid taking your
vehicle to areas where appropriate fuel is
not available.
When transferring the registration of your
vehicle to another country, state, province
or district,it may be necessary to modify
the vehicle to meet local laws and regula-
tions.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications
may differ.
When any vehicle is to be taken into
another country, state, province or district
and registered, its modifications, trans-
portation, and registration are the respon-
sibility of the user. INFINITI is not
