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 12,5000
miles (200,000 km) or 180 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(6) Replace spark plug when the plug gap
exceeds 0.055 in (1.4 mm) even if within
specified replacement mileage.
(7) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.

NOTE:
Maintenance items with “$ ” should be
performed more frequently according to
“Maintenance under severe driving condi-
tions” (P.9-13).
(1) Periodic maintenance is not required.
(2) If using a car-top carrier, or driving on
rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000
km) or 24 months.
(3) Refer to “Tire rotation” under “General
maintenance” (P.9-2).

The maintenance intervals shown on the
preceding pages are for normal operating
conditions. If the vehicle is mainly operated
under severe driving conditions as shown
below, more frequent maintenance must be
performed on the following items as shown
in the table.
Severe driving conditions
.Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.
. Operating in hot weather in stop-and-go
“rush hour” traffic.
. Extensive idling and/or low speed driving
for long distances, such as police, taxi or
door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy, or salt spread
roads.
. Using a car-top carrier.
