FUEL-FILLER CAP
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 pos-
sible injury. It could also cause the
Malfunction Indicator Light (MIL) to
come on.
• Never pour fuel into the throttle body to
attempt to start your vehicle.
• Do not fill a portable fuel container in the
vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with
the container while you are filling it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
• Do not use a fuel containing more than
15% ethanol in your vehicle. For addi-
tional information, see “Fuel recommen-
dation” (P. 10-4).
•
The Loose Fuel Cap warning message will
be displayed if the fuel-filler cap is not
properly tightened. It may take a few driv-
ing trips for the message to be displayed.
Failure to tighten the fuel-filler cap prop-
erly after the Loose Fuel Cap warning
is displayed may cause the Malfunction
Indicator Light (MIL) to illuminate.
• Failure to tighten the fuel-filler cap
properly may cause theMalfunc-
tion Indicator Light (MIL) to illuminate.
If the
light illuminates because the
fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive
the vehicle. The
light should turn off
after a few driving trips. If thelight
does not turn off after a few driving
trips, have the vehicle inspected. It is rec-
ommended that you visit an INFINITI
retailer for this service.

WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
damage the spark plugs.
If replacement is required, it is recommended
that you visit an INFINITI retailer for this
service.
WARNING
• Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only
cleans the intake air, it also stops the
flame if the engine backfires. If the air
cleaner is not installed and the engine
backfires, you could be burned. Never
drive with the air cleaner filter off. Be
cautious working on the engine when the
air cleaner is off. •
Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result in
serious injury.
To remove the filter from the air cleaner, push
the clips
OAand pull the cover upward.
The viscous paper type filter element should
not be cleaned and reused. Replace it accord-
ing to the maintenance log shown in the
“Maintenance and schedules” section of this
manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover with
a damp cloth.
NOTE:
After installing a new air cleaner filter,
make sure the air cleaner cover is seated in
the housing and latch the clips
OA.

ditional information on the proper mixture for
your area, see “Engine cooling system”
(P. 8-4).)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter:Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity, see
“Recommended fluids/lubricants and capaci-
ties” (P. 10-2).

noise increases. Adjust valve clearance if
necessary.
Evaporative emissions control vapor lines*:Check vapor lines for leaks or looseness.
Tighten connections or replace parts as
necessary.
Fuel lines/connections*: Check the fuel
hoses, piping and connections for leaks,
looseness, or deterioration. Tighten connec-
tions or replace parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY

RECOMMENDED FLUIDS/
LUBRICANTS AND CAPACITIES
10-2Technical and consumer information

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, qual-
ity and viscosity engine oil to ensure satisfac-
tory engine life and performance. For addi-
tional information, see "Recommended fluids/
lubricants and capacities" (P. 10-2). INFINITI
recommends the use of an energy conserving
oil in order to improve fuel economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification or
International Lubricant Standardization andApproval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
