required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
air conditioner system. For additional infor-
mation, refer to “Air conditioner system re-
frigerant and oil recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
It is recommended that you visit an INFINITI
retailer for servicing your “environmentally
friendly” air conditioning system.WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, any air conditioner service
should be done only by an experienced
technician with proper equipment.

∙ Do not use fuel that contains the octanebooster 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 indi-
cate 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 reformu-
lated 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
methanol 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
contain a suitable amount of appropri-
ate cosolvents and corrosion inhibitors.
If not properly formulated with appro-
priate cosolvents and corrosion inhibi-
tors, such methanol blends may cause
fuel system damage and/or vehicle per-
formance problems. At this time, suffi-
cient 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

10-8Technical and consumer information

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 avail-
able.
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.

(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect 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 on 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
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea- sured in step 2. The rear bumper should
be no higher than the reference height
measured 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 unpre-
dictably 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 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 la-
bel.
∙ Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.
