EXPLANATION OF MAINTENANCE
ITEMS Additional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.
Emission control system
maintenance Drive belts*: Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter: Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines: Check vapor lines and
connections for failure or looseness. If leaks
are found, replace them.
Fuel lines: Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*: Drain and flush the cooling
system.
Engine oil & oil filter*: Under normal driving conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*: Replace with new plugs having
the correct heat range.
Chassis and body maintenance Brake lines & cables: Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Automatic transmission fluid*: Using auto-
matic transmission fluid other than Genuine
Nissan ATF Matic Fluid J will cause deteriora-
tion in driveability and automatic transmission
durability, and may damage the automatic
transmission, which is not covered by the
INFINITI new vehicle limited warranty. If
checking or replacement is required, we rec-
ommend your INFINITI retailer for servicing.
Under severe driving conditions, the fluid should be replaced at the specified interval.
Manual transmission oil & differential gear
oil*: Check the oil level and visually inspect for
signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts: Check for damage, looseness and leak-
age of oil or grease. Under severe driving
conditions, more frequent inspection should be
performed.
Exhaust system: Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
In-cabin microfilter: Under normal condi-
tions, this microfilter should be replaced in
accordance with the maintenance schedule.
However, in some situations, the microfilter
may clog more rapidly (depending on the air
conditioner's working environment). If this hap-
pens, the air flow may decrease, or the win-
dows may fog up easily when the air condi-
tioner is in use, the microfilter should be
replaced immediately at your INFINITI retailer.

FUEL RECOMMENDATION
Sedan models Use unleaded regular gasoline with an octane
rating of at least 87 AKI (Anti-Knock Index)
number (Research octane number 91).
For improved vehicle performance, INFINITI
recommends the use of unleaded premium
gasoline with an octane rating of at least 91
AKI number (Research octane number 96).
Coupe models Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87
AKI number (Research octane number 91)
may be temporarily used, but only under the
following precautions:
O Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.
O Avoid full throttle driving and abrupt accel-
eration.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso- line is recommended.
CAUTION Using a fuel other than that specified
could adversely affect the emission con-
trol devices and systems, and could
also affect the warranty coverage.
Under no circumstances should a
leaded gasoline be used, since this will
damage the three-way catalyst.
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 gaso-
line when available.
Gasoline containing oxygenates Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their pres-
ence. 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.
O The fuel must be unleaded and have an
octane rating no lower than that recom-
mended for unleaded gasoline.
O If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
O If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of appro-
priate cosolvents and corrosion inhibi-
tors. If not properly formulated with ap-
propriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are suit-
able for use in INFINITI vehicles.
If any driveability problems such as engine
stalling and hard hot starting are experienced Technical and consumer information
10-3
Z 02.7.29/V35-D/V5.0
X

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 refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additives INFINITI does not recommend the use of any
fuel additives (i.e. 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 tips In most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico. Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, 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 your dealer correct the condi-
tion. 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.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil It is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life
and performance. INFINITI recommends the
use of a low friction oil (energy conserving oil)
in order to improve fuel economy and con-
serve energy. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.
Only those engine oils with the American Pe-
troleum Institute (API) certification mark on the front of the container should be used. This type
of oil supersedes the existing API SG, SH, or
SJ and Energy Conservin gI&II categories.
If you cannot find engine oil with the API
certification mark, use an API grade SG/SH,
Energy Conservin gI&IIorAPI grade SJ or
SL, Energy conserving oil. An oil with a single
designation SG or SH, or in combination with
other categories (for example, SG/CC or
SG/CD) may also be used if one with the API
certification mark cannot be found. An ILSAC
grade GF-I, GF-II, GF-III oil can also be used.
INFINITI recommends mineral based oils.
These oils must however, meet the API quality and SAE viscosity ratings specified for your
vehicle.
Oil additives INFINITI 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 viscosity The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the ve-
hicle will be operated before the next oil
change. The recommended SAE viscosity
number chart shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.
Selecting the correct oil filter Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in change intervals.STI0293

Change intervals The 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 re-
duce engine life. Damage to engines caused
by improper maintenance or use of incorrect
oil and filter quality and/or viscosity is not
covered by the new INFINITI vehicle 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. Op-
eration under the following conditions may
require more frequent oil and filter changes.
O repeated short distance driving at cold out-
side temperatures,
O driving in dusty conditions,
O extensive idling,
O towing a trailer,
O stop and go ªrush hourº traffic.
O aggressive driving RECOMMENDED SAE VISCOSITY
NUMBER
SAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30,
10W-40 viscosity oil may be used if the
ambient temperature is above 0ÉF (þ18ÉC). AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS The air conditioning system in this INFINITI
vehicle must be charged with the refriger-
ant 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 lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner sys-
tem 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 govern-
mental regulations require the recovery and
recycling of any refrigerant during automotive
air conditioning system service. Your INFINITI
retailer has the trained technicians and equip-
ment needed to recover and recycle your air
conditioning system refrigerant.
Contact your INFINITI retailer when servicing
your air conditioning system. TI1028-C
