NOTE:
(1) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.
(2) Periodic maintenance is not required.
(3) 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.
(4) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze 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 cool-
ant.
(5) First replacement interval is 125,000
miles (200,000 km) or 180 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(6) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.
*: Maintenance items and intervals with “*”
are recommended by INFINITI for reliable
vehicle operation. The owner need not to
perform such maintenance in order to
maintain the emission warranty or manu-
facturer recall liability. Other maintenance
items and intervals are required.
