FUEL RECOMMENDATION

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

If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) may be temporarily 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 maxi-
mum vehicle performance.

CAUTION

•

Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.

•

Under no circumstances should a leaded
gasoline be used, because this will dam-
age 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 contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the

INFINITI

New

Vehicle

Limited

Warranty.

Technical and consumer information

10-3

•

Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect ve-
hicle performance and vehicle emissions.
Not all fuel dispensers are labeled to in-
dicate 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 refor-
mulated gasoline.

•

U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage 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 de-
veloped this specification to improve emis-
sion control system and vehicle performance.
Ask your service station manager if the gaso-
line meets the WWFC specifications.

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
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 recom-
mended for unleaded gasoline.

•

If an oxygenate-blend other than metha-
nol blend is used, it should contain no more
than 15% oxygenate.

•

If a methanol blend is used, it should con-
tain no more than 5% methanol (methyl
alcohol, wood alcohol). It should also con-
tain a suitable amount of appropriate co-
solvents and corrosion inhibitors. If not
properly formulated with appropriate co-
solvents and corrosion inhibitors, such
methanol blends may cause fuel system
damage and/or vehicle performance prob-
lems. At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.

If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a non-oxygenate fuel or
a fuel with a low blend of MTBE.

Take care not to spill gasoline during refuel-
ing. 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

10-4

Technical and consumer information

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 Ve-
hicle (FFV). Do not use E-85 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.

Fuel containing MMT

MMT, or methylcyclopentadienyl manganese
tricarbonyl, is an octane boosting additive.
INFINITI does not recommend the use of fuel
containing MMT. Such fuel may adversely
affect vehicle performance, including 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 details.

Aftermarket fuel additives

INFINITI does not recommend the use of any
aftermarket fuel additives (for 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 con-
tain active solvents or similar ingredients that
can be harmful to the fuel system and engine.

Octane rating tips

Using unleaded gasoline with an octane rat-
ing lower than recommended 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 per-
sistent 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 recom-
mended that you 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 may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.

However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a 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
RECOMMENDATIONS

Selecting the correct oil

It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, see "Recommended
fluids/lubricants and capacities" (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 Ameri-
can Petroleum Institute (API) certification or

International Lubricant Standardization 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 speci-
fied 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 impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.

Selecting the correct oil filter

Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN 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. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life.

LTI2061

10-6

Technical and consumer information

CAUTION

Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the INFINITI New Vehicle Limited
Warranty.

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.

Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at cold out-

side temperatures

• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting

For additional information on maintenance
schedules, see “Maintenance and schedules”
(P. 9-2).

AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS

The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and the oil, Genu-
ine NISSAN A/C System Oil Type ND-OIL12
or the exact equivalents.

CAUTION

The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.

The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant.

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

When planning to drive your INFINITI ve-
hicle in another country,

you should first find

out if the fuel available is suitable for your
vehicle's engine.

Using fuel with an octane rating that is too
low 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 reg-
istered, its modifications, transportation,
and registration are the responsibility of the
user. INFINITI is not responsible for any in-
convenience that may result.

WARNING

•

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

•

Do not allow people to ride in any
area of your 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 including:
standard and optional equipment,
fluids, emergency tools, and spare
tire assembly. This weight

does not

include passengers 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, pas-
sengers,

luggage,

hitch,

trailer

tongue load and any other optional
equipment. This information is lo-
cated on the F.M.V.S.S./C.M.V.S.S.
certification label.

• GAWR (Gross Axle Weight Rating) -

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

• GCWR (Gross Combined Weight

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

• Vehicle Capacity Weight, Load limit,

Total load capacity - maximum total
weight limit specified of the load
(passengers and cargo) for the ve-
hicle. This is the maximum combined
weight of occupants and cargo that
can be loaded into the vehicle. If the
vehicle is used to tow a trailer, the
trailer tongue weight must be in-
cluded as part of the cargo load. This
information is located on the Tire
and Loading Information label.

• Cargo capacity - permissible weight

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

VEHICLE LOADING INFORMATION

Technical and consumer information

10-15

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 Capacity” on the
Tire and Loading Information label.

To get “the combined weight of occu-
pants and cargo”, add the weight of all
occupants, then add the total luggage
weight. Examples are shown in the
following illustration.

Steps for determining correct load
limit

1. Locate the statement “The com-

bined weight of occupants and

LTI2320

Example

10-16

Technical and consumer information

cargo should never exceed XXX lbs.
or XXX kg” 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 lbs. or XXX kg.

4. The resulting figure equals the

available amount of cargo and lug-
gage load capacity. For example, if
the XXX amount equals 1,400 lbs.
and there will be five 150 lbs. pas-
sengers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1,400-
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 GVWR
or the GAWR for your vehicle. For ad-
ditional information, see “Measure-
ment of weights” (P. 10-18).

Also check tires for proper inflation
pressures. For additional information,
see “Tire and Loading Information la-
bel” (P. 8-28).

SECURING THE LOAD

There are luggage hooks located in the cargo
area as shown. The hooks can be used to
secure cargo with ropes or other types of
straps.

When securing items using luggage hooks
located on the side finisher do not apply a
load over more than 6.5 lbs. (29 N) to a single
hook.

The luggage hooks that are located on the
floor should have loads less than 110 lbs.
(490 N) to a single hook.
