FUEL INFORMATION
VK56VD engine
INFINITI recommends the use of 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, you may use unleaded regular gasoline
with an octane rating of at least 87 AKI
number (Research octane number 91), but
you may notice a decrease in 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 E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed
to run on E-15 or E-85 fuel. Using E-
15 or E-85 fuel in a vehicle not
specifically designed for E-15 or E-
85 fuel 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 war-
ranty.
. 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 10% oxygenate.
(MTBE may, however, be added up to
15%.)

SPECIFICATIONS

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.

IN ANOTHER COUNTRYVEHICLE IDENTIFICATION

measured reference height when loaded,
the vehicle may handle unpredictably
which could cause a loss of vehicle
control and cause serious personal injury
or property damage.
Sway control device
Sudden maneuvers, wind gusts and buffet-
ing caused by other vehicles can affect
trailer handling. Sway control devices may
be used to help control these affects. If you
choose to use one, contact a reputable
trailer hitch supplier to make sure the sway
control device will work with the vehicle,
hitch, trailer and the trailer’s brake system.
Follow the instructions provided by the
manufacturer for installing and using the
sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lb
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lb
(1,588 kg).
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 5,000 lb
(2,267 kg).
Class IV hitch
Class IV trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 10,000 lb
(4,545 kg). A weight distributing hitch
should be used to tow trailers that weigh
over 5,000 lb (2,267 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000 lb
(4,545 kg) maximum weight rating, but your
vehicle is only capable of towing the max-
imum trailer weights shown in the “Towing
Load/Specification” chart earlier in this
section.
CAUTION
.Do not use axle-mounted hitches.
. Do not modify the vehicle exhaust
system, brake system, etc.
. Do not attach any additional hitches
to your vehicle because a hitch is
already mounted to your vehicle frame.
Tire pressures
.
When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
. Trailer tire condition, size, load
rating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains
Always use a suitable chain between your
vehicle and the trailer. The safety chains
should be crossed and should be attached to
the hitch, not to the vehicle bumper or axle.
Be sure to leave enough slack in the chains to
permit turning corners.
