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

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.

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

condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
O Always secure items in the trailer to prevent
load shifts while driving.
O Be certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tips In order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
O Always secure items in the trailer to prevent
load shift while driving.
O Avoid abrupt starts, acceleration or stops.
O Avoid sharp turns or lane changes.
O Always drive your vehicle at a moderate
speed.
O Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so, and if your vehicle is equipped with automatic transmission, first apply the
parking brake and block the wheels, and
then move the transmission selector lever
into the P (Park) position. If you move the
selector lever to the P (Park) position be-
fore blocking the wheels and applying the
parking brake, the transmission may be
damaged.
O When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending on a long grade, down-
shift the transmission to a lower gear and
reduce speed to reduce chances of engine
overloading and/or overheating.
O If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
O Trailer towing consumes more fuel than
normal circumstances.
O Avoid towing a trailer for the first 500 miles
(800 km).
O Have your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule. O When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
O Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being passed
by larger vehicles, be prepared for possible
changes in crosswinds that could affect
vehicle handling. If swaying does occur,
firmly grip the steering wheel, steer straight
ahead, and immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
O Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer
must also pass the other vehicle before you
can safely change lanes.
O To maintain engine braking efficiency and
electrical charging performance, do not use
sixth gear (manual transmission) or fifth
position (automatic transmission).
O Avoid holding the brake pedal down too
long or too frequently such as on long
down-hill sections of road. This could cause

the brakes to overheat, resulting in reduced
braking efficiency. Shift down and use en-
gine braking.
When towing a trailer, change transmission
oil more frequently.
See ªPeriodic maintenance schedulesº in
the ª9. Maintenanceº section. Shift down
and use engine braking. DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform
to federal safety requirements in addition to
these grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
WARNING The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.UNIFORM TIRE QUALITY

IN THE EVENT OF A COLLISION Unfortunately, accidents do occur. In this un-
likely event, there is some important informa-
tion you should know. Many insurance compa-
nies routinely authorize the use of non-
genuine collision parts in order to cut costs,
among other reasons.
Insist on the use of Genuine Infiniti
Collision Parts! If you want your vehicle to be restored using parts made to INFINITI's original exacting
specifications Ð if you want to help it to last
and hold its resale value, the solution is
simple. Tell your insurance agent and your
repair shop to only use Genuine Infiniti
Collision Parts. INFINITI does not warrant
non-Infiniti parts, nor does Infiniti's warranty
apply to damage caused by a non-genuine
parts.
Using Genuine Infiniti Parts can help protect
your personal safety, preserve your warranty
protection and maintain the resale value of
your vehicle. And if your vehicle was leased,
using Genuine Infiniti Parts may prevent or
limit unnecessary excess wear and tear ex-
penses at the end of your lease.
INFINITI designs its hoods with crumple zones
to minimize the risk that the hood will penetrate
the windshield of your vehicle in an accident.
Non-genuine (imitation) parts may not provide
such built in safety features. Also, non-genuine
parts often show premature wear, rust and
corrosion.
Why should you take a chance? In over 40 states, the law says you must be
advised if non-genuine parts are used to repair
your vehicle. And some states/provinces have
enacted laws that restrict insurance compa-
nies from authorizing the use of non-genuineOWNER'S MANUAL/SERVICE
