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 withunleaded 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.
• 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 etha-
nol dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropri-
ate 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.

Technical and consumer information10-9

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.

NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge brakes.
If you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the surge
brake, hitch or trailer manufacturer to de-
termine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.With the ignition switch in the ON position
and the doors closed, allow the vehicle to
stand for several minutes so that it can
level.
2. Measure the height of a reference point on the front and rear bumpers at the cen-
ter of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height measured
in step 2. The rear bumper should be no
higher than the reference height mea-
sured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no higher
than the measured reference height when
the trailer is attached. If the rear bumper is
higher than the measured reference height
when loaded, the vehicle may handle un-
predictably which could cause a loss of ve-
hicle control and cause serious personal in-
jury 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 sup-
plier 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 lbs.
(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 lbs.
(1,587 kg).
Tire pressures
• When towing a trailer, inflate the vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information label.
• Trailer tire condition, size, load rating and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer's specifications.
Safety chains
Always use suitable safety chains 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.
The safety chains can be attached to the
bumper if the hitch ball is mounted to the
bumper. Be sure to leave enough slack in the
chains to permit turning corners.
