REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tippedA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in theMainte-
nance and schedules section of this manual. Do
not service iridium-tipped spark plugs by clean-
ing or regapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.
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 re-
move 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 en-
gine 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.

Engine coolant*:
Replace coolant at the specified interval. When
adding or replacing coolant, be sure to use only
Genuine NISSAN Long Life Antifreeze/Coolant
(blue) or equivalent with the proper mixture. (For
additional information on the proper mixture for
your area, refer to “Engine cooling system” in the
“Do-it-yourself” section of this manual.)
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 viscos-
ity refer to “Recommended fluids/lubricants and
capacities” in the “Technical and consumer infor-
mation” section of this manual.
Engine valve clearance*:
Inspect only if valve noise increase. 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*:
Check the fuel hoses, piping and connections for
leaks, looseness, or deterioration. Tighten con-
nections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new plugs
of the same type as originally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables:
Visually inspect for proper installation. Check for
chafing, cracks, deterioration, and signs of leak-
ing. Replace any deteriorated or damaged parts
immediately.
Brake pads and rotors:
Check for wear, deterioration and fluid leaks.
Replace any deteriorated or damaged parts im-
mediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler and
hangers for leaks, cracks, deterioration, and dam-
age. Tighten connections or replace parts as
necessary.In-cabin microfilter:
Replace at specified intervals. When driving for
prolonged periods in dusty conditions, replace
the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease leak-
age. (AWD)
Steering gear and linkage, axle and sus-
pension parts, drive shaft boots:
Check for damage, looseness, and leakage of oil
or grease. Under severe driving conditions, in-
spect more frequently.
Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions under
“Explanation of general maintenance items” in
this section. When rotating tires, check for dam-
age and uneven wear. Replace if necessary.
Transmission fluid/oil, differential oil and
transfer case oil:
Visually inspect for signs of leakage at specified
intervals.
Replace at specified intervals.

NOTE:
(1) After 40,000 miles (64,000 km) or 48 months, inspect every 10,000 miles (16,000 km) or 12 months. Replace the drive belts if found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000 km)
or 60 months.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ration of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the
factory fill coolant.
(6) Replace spark plug when the plug gap exceeds 0.055 in (1.4 mm) even if within specified periodic replacement mileage.
(7) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform such
maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
