FUEL INFORMATION

Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).

If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be tem-
porarily used, but only under the following
precautions:
. Have the fuel tank filled only partially

with unleaded regular gasoline, and fill
up with unleaded premium gasoline as
soon as possible.

. Avoid full throttle driving and abrupt

acceleration.

Use unleaded premium gasoline for max-
imum vehicle performance.

CAUTION

. Using a fuel other than that specified

could adversely affect the emission
control system, and may also affect
warranty coverage.

. Under no circumstances should a

leaded gasoline be used, because this
will damage the three-way catalyst.

. Do not use a fuel containing more

than 15% ethanol in your vehicle.
Your vehicle is not designed to run on
a fuel containing more than 15%
ethanol. Using a fuel containing more
than 15% ethanol in a vehicle not
specifically designed for a fuel con-
taining more than 15% ethanol can
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.

. Do not use fuel that contains the

octane booster methylcyclopentadie-
nyl manganese tricarbonyl (MMT).
Using fuel containing MMT may
adversely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
MMT content, so you may have to
consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of
MMT in reformulated gasoline.

. U.S. government regulations require

ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percen-
tage for that region.

Gasoline specifications

INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers
developed this specification to improve
emission system and vehicle performance.
Ask your service station manager if the
gasoline meets the World-Wide Fuel Char-
ter (WWFC) specifications.

Reformulated gasoline

Some fuel suppliers are now producing
reformulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. INFINITI supports efforts towards
cleaner air and suggests that you use
reformulated gasoline when available.

Gasoline containing oxygenates

Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. 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.
. The fuel should be unleaded and have an

octane rating no lower than that re-
commended for unleaded gasoline.

. If an oxygenate-blend, excepting a

methanol blend, is used, it should con-
tain no more than 15% oxygenate.

. 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 ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or vehi-
cle 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-oxyge-
nate 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 fuel

E-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. U.S. government regula-
tions require fuel ethanol dispensing pumps
to be identified with small, square, orange
and black label with the common abbrevia-
tion or the appropriate percentage for that
region.

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. government regulations require fuel
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.

Fuel containing MMT

MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to

consult your gasoline retailer for more de-
tails.

Aftermarket fuel additives

INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. 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 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,
it is recommended you have an INFINITI
retailer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.

Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
may cause excessive fuel consumption or

Technical and consumer information

damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer for servicing.

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 grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.

Select only engine oils that meet the Amer-
ican Petroleum Institute (API) certification

or International Lubricant Standardization
and Approval Committee (ILSAC) certifica-
tion 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 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
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 filter

Your 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 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 reduce engine life. Damage to engines
caused by improper maintenance or use of
incorrect oil and filter quality and/or vis-
cosity is not covered by the new INFINITI
vehicle limited warranties.

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 recom-

mended change interval. Oil and filter
change intervals depend upon how you use
your vehicle.

AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT
RECOMMENDATIONS

The air conditioning system in your INFINITI
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
AE-10.

CAUTION

The use of any other refrigerant or
lubricant may cause severe damage to
the air conditioning system and may
require the replacement of all air condi-
tioner 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 recov-
ery and recycling of any refrigerant during
automotive air conditioning system service.
Your INFINITI retailer has the trained tech-
nicians and equipment needed to recover
and recycle your air conditioning system

refrigerant.

It is recommended you visit an INFINITI
retailer when servicing your air conditioning
system.

Technical and consumer information

If you plan to travel in another country, 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 regulations.

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, transpor-
tation, and registration are the responsi-
bility of the user. INFINITI is not responsible
for any inconvenience that may result.

This vehicle is equipped with air deflectors in
front of the front wheels. The deflectors will
change the air flow to help improve aero-
dynamic performance.

When transporting your vehicle on a trailer,
the air deflectors may interfere with a steep
slope to a trailer bed. In this case, remove the
deflectors from the undercover of the ve-
hicle.

1. Loosen three screws as shown and

remove the left-side air deflector

.

2. Tighten the removed screw

in its

original position.

3. Perform the same procedure to remove

the right-side air deflector.

4. Store the two air deflectors and four

screws to reinstall in the reverse order.

5. When reinstalling, make sure all six

screws are firmly tightened on both air
deflectors.

REMOVING AIR DEFLECTORS

WARNING

.

It is extremely dangerous to
ride in a cargo area inside the
vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed.

.

Do not allow people to ride in
any area of vehicle that is not
equipped with seats and seat
belts.

.

Be sure everyone in your vehicle
is in a seat and using a seat belt
properly.

TERMS
It is important to familiarize yourself
with the following terms before load-
ing your vehicle:

.

Curb Weight (actual weight of

your vehicle) - vehicle weight in-
cluding: standard and optional
equipment, fluids, emergency
tools, and spare tire assembly. This
weight does not include passen-

gers and cargo.

.

GVW (Gross Vehicle Weight) -

curb weight plus the combined
weight of passengers and cargo.

.

GVWR (Gross Vehicle Weight Rat-

ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the F.M.V.S.S./C.M.
V.S.S. label.

.

GAWR (Gross Axle Weight Rating)

- maximum weight (load) limit
specified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. label.

.

GCWR (Gross Combined Weight

Rating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer.

.

Vehicle Capacity Weight, Load

limit, Total load capacity - max-
imum total weight limit specified
of the load (passengers and cargo)
for the vehicle. This is the max-
imum combined weight of occu-

pants and cargo that can be
loaded into the vehicle. If the
vehicle is used to tow a trailer,
the trailer tongue weight must be
included as part of the cargo load.
This information is located on the
Tire and Loading Information la-
bel.

.

Cargo capacity - permissible

weight of cargo, the weight of
total occupants weight subtracted
from the load limit.

Technical and consumer information

10-15

VEHICLE LOADING INFORMATION

10-16

Technical and consumer information

STI0365

VEHICLE LOAD CAPACITY
Do not exceed the load limit of your
vehicle shown as “The combined
weight of occupants and cargo” on
the Tire and Loading Information
label. Do not exceed the number of
occupants shown as “Seating Capa-
city” on the Tire and Loading Infor-
mation label.
To get “the combined weight of
occupants and cargo”, add the weight
of all occupants, then add the total
luggage weight. Examples are shown

in the illustration.

Steps for determining correct load
limit

1.

Locate the statement “The com-
bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs” on your vehicle’s
placard.

2.

Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.

3.

Subtract the combined weight of
the driver and passengers from

XXX kg or XXX lbs.

4.

The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehicle,
the amount of available cargo and
luggage load capacity is 650 lbs.
(1400 − 750 (5 x 150) = 650 lbs or
640 − 340 (5 x 70) = 300 kg.)

5.

Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.

6.

If your vehicle will be towing a
trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity
of your vehicle.

Before driving a loaded vehicle, con-
firm that you do not exceed the Gross
Vehicle Weight Rating (GVWR) or the

Gross Axle Weight Rating (GAWR)
for your vehicle. (See “Measurement
of weights” (P.10-17).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.

LOADING TIPS

.

The GVW must not exceed GVWR

or GAWR as specified on the F.M.
V.S.S./C.M.V.S.S. certification la-
bel.

.

Do not load the front and rear axle

to the GAWR. Doing so will exceed
the GVWR.

WARNING

.

Properly secure all cargo to help
prevent it from sliding or shift-
ing. Do not place cargo higher
than the seatbacks. In a sudden
stop or collision, unsecured car-
go could cause personal injury.

.

Do not load your vehicle any
heavier than the GVWR or the
m a x i m u m f r o n t a n d r e a r

GAWRs. If you do, parts of
your vehicle can break, tire
damage could occur, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury.

.

Overloading could not only
shorten the life of your vehicle
and the tires, but also could
lead to hazardous vehicle hand-
ling and long braking distance.
This may cause a premature tire
malfunction, which could result
in a serious accident and perso-
nal injury. Failures caused by
overloading are not covered by
the vehicle’s warranty.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. Indivi-
dual axle loads should not exceed

either of the gross axle weight ratings
(GAWR). The total of the axle loads
should not exceed the gross vehicle
weight rating (GVWR). These ratings
are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all
weights below the ratings.

Technical and consumer information

10-17

10-18

Technical and consumer information

Do not tow a trailer with your
vehicle.

FLAT TOWING

Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.

CAUTION

. Failure to follow these guidelines can

result in severe transmission damage.

. Whenever flat towing your vehicle,

always tow forward, never back-
ward.

. DO NOT tow any Automatic Trans-

mission (AT) vehicle with all four
wheels on the ground (flat towing).
Doing so WILL DAMAGE internal
transmission parts due to lack of
transmission lubrication.

. DO NOT tow any All-Wheel Drive

(AWD) vehicle with any of the wheels
on the ground. Doing so may cause
serious and expensive damage to the
powertrain.

. For emergency towing procedures

refer to “Towing recommended by

INFINITI” (P.6-10).

Automatic Transmission (AT)

All-Wheel Drive (AWD) models:
Do not tow an AWD vehicle with any of the
wheels on the ground.

Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s
drive wheels. Always follow the dolly man-
ufacturer’s recommendations when using
their product.

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.

Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:

Treadwear 200 Traction AA Temperature A

TREADWEAR

The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
