4. Insert the support rod3into the slot4on the underside of the hood.
5. When closing the hood, replace the sup- port rod in its original position
5, slowly
lower the hood to about8–12in.(20–
30 cm) above the hood lock, then let it
drop. Make sure the hood is securely
latched.
WARNING
•Make sure the hood is completely closed
and latched before driving. Failure to do
so could cause the hood to fly open and
result in an accident.
•If you see steam or smoke coming from
the engine compartment, to avoid injury
do not open the hood.
OPENING FUEL-FILLER DOOR

WARNING
•Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled. Al-
ways stop the engine and do not smoke
or allow open flames or sparks near the
vehicle when refueling.
•Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off au-
tomatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
•Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury.

3-16Pre-driving checks and adjustments

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
in the "10. Technical information" section
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
•It is advisable to secure or remove any
loose clothing and any jewelry, such as
rings, watches, etc. before working on
your vehicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is proper ventilation for exhaust gases to
escape.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

FUEL RECOMMENDATION
INFINITI recommends the use of unleaded
premium gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number (Re-
search octane number 95).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 89 AKI number (Research oc-
tane number 93) 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 ac-
celeration.
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 war-
ranty coverage.
•Under no circumstances should a leaded
gasoline be used, because this will dam-
age 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 de-
signed for E-15 or E-85 fuel can ad-
versely affect the emission control de-
vices and systems of the vehicle.
Damage caused by such fuel is not cov-
ered by the INFINITI New Vehicle Lim-
ited Warranty.
•Do not use fuel that contains the octane
booster methylcyclopentadienyl man- ganese tricarbonyl (MMT). Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. 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 identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
