REPLACING SPARK PLUGS
If replacement is required, it is recom-
mended you visit a NISSAN dealer for this
service.
Iridium platinum-tipped spark
plugs
It is not necessary to replace the iridium
platinum-tipped spark plugs as frequently
as the conventional type spark plugs
since they will last much longer. Follow
the maintenance schedule shown in the
“9. Maintenance and schedules” section.
Do not reuse the iridium platinum-tipped
spark plugs by cleaning or regapping.
Always replace spark plugs with recom-mended or equivalent ones.
SPARK PLUGS

The following descriptions are provided
to give you a better understanding of the
scheduled maintenance items that
should be regularly checked or replaced.
The maintenance schedule indicates at
which mileage/time intervals each item
requires service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day op-
eration. Refer to “General maintenance”
(P.9-2).
Items marked with “*” are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform main-
tenance on these items in order to
maintain the warranties which come with
your vehicle. Other maintenance items
and intervals are required.
When applicable, additional information
can be found in the “8. Do-it yourself”
section of this manual.
NOTE:
NISSAN does not advocate the use of
non-OEM approved aftermarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the aftermar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by
NISSAN.For recommended fuel, lubricants,
fluids, grease, and refrigerant, refer to
“Capacities and recommended fluids/
lubricants” (P.10-2) of this manual.
EMISSION CONTROL SYSTEM MAIN-
TENANCE
Drive belt*:
Check engine drive belt for wear, fraying
or cracking and for proper tension. Re-
place any damaged drive belt.
Engine air filter:
Replace at specified intervals. When driv-
ing for prolonged periods in dusty condi-
tions, check/replace the filter more
frequently.
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 equiva-
lent with the proper mixture. (Refer to
“Engine cooling system” (P.8-4) to deter-
mine the proper mixture for your area.)
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 “Capacities
and recommended fluids/lubricants”
(P.10-2).
Engine valve clearance*:
Inspect only if valve noise increases.
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 filter
Periodic maintenance is not required (in-
tank type filter).
Fuel lines*:
Check the fuel hoses, piping and connec-
tions for leaks, looseness, or deterioration.
Tighten connections or replace parts as
necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.

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 belt if found damaged.
(2) If operating mainly in dusty condi-
tions, more frequent maintenance may
be required.
(3) Periodic maintenance is not re-
quired.
(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% anti-
freeze and 50% demineralized or dis-
tilled 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 0.053 in (1.35 mm) even if
within specified replacement mileage.
(7) Periodic maintenance is not re-
quired. However, if valve noise in-
creases, inspect valve clearance.
