Additional information
NOTE FOR ENGINE COOLANT *:
(1) 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.
(2) 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.
* Maintenance items and intervals with “ *
” are recommended by NISSAN 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.
NOTE FOR SPARK PLUGS:
(1) Replace every 105,000 miles
(168,000 km)
(2) Replace spark plug when the plug gap
exceeds 0.045 in (1.25 mm) even if within
specified replacement mileage.
