REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tipped
Aspark plugs as frequently as conventional
type spark plugs because they last much lon-
ger. Follow the maintenance log shown in the
"Maintenance and schedules" section of this
manual. Do not service iridium-tipped spark
plugs by cleaning or regapping.
∙ Always replace spark plugs with recom-
mended 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 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.

8-16Do-it-yourself

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 ad-
ditional 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 viscosity refer to
“Recommended fluids/lubricants and capaci-
ties” in the “Technical and consumer informa-
tion” section of this manual.
Engine valve clearance*: Inspect only if valve
noise increases. Adjust valve clearance if nec-
essary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as nec-
essary. Fuel lines*:
Check the fuel hoses, piping and
connections for leaks, looseness, or deterio-
ration. Tighten connections 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
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace
any deteriorated or damaged parts immedi-
ately.
Brake pads and rotors: Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks,
deterioration, and damage. Tighten connec-
tions or replace parts as necessary.
In-cabin microfilter: Replace at specified in-
tervals. When driving for prolonged periods in
dusty conditions, replace the filter more fre-
quently.
Propeller shaft(s): Check for damage, loose-
ness, and grease leakage. (AWD) Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for dam-
age, looseness, and leakage of oil or grease.
Under severe driving conditions, inspect 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 ro-
tating tires, check for damage 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.
9-6Maintenance and schedules

The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions, varying
road surfaces, individual driving habits and
vehicle usage, additional or more frequent
maintenance may be required.After 120,000 miles (192,000 km)/
144 months, continue maintenance at the
same mileage/time interval.

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 ratio 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.
