equipped) hold securely in all latched posi-
tions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition require frequent
checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as: 1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4) for exhaust gas (carbon
monoxide).) Fluid leaks:
Check under the vehicle for fuel,
oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines: Check
the level when the fluid is cold, with the
engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.

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%.)

.E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices and
systems of the vehicle and should not be
used. Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.
. 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. Do not use E-15 in your
vehicle. U.S. government regulations require
fuel ethanol dispensing pumps to be identi-
fied with small, square, orange and black
label with the common abbreviation 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

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
