WARNING
Be sure the ignition switch is placed in
the OFF or LOCK position before servic-
ing drive belt. The engine could rotate
unexpectedly.
1. Visually inspect the belt for signs of un- usual wear, cuts, fraying or looseness. If
the belt is in poor condition or is loose, have it replaced or adjusted. It is recom-
mended that you visit a NISSAN dealer
for this service.
2. Have the belt checked regularly for condition and tension in accordance
with the maintenance schedule found
in the "Maintenance and schedules"
section of this manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
Aspark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
∙ Always replace spark plugs with rec-
ommended 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 re-
move the spark plugs. An incorrect
socket can damage the spark plugs.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
∙ Operating the engine with the air cleaner filter off can cause you or oth-
ers to be burned. The air cleaner filter
not only cleans the intake air, it also
stops the flame if the engine back-
fires. 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. ∙ Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
To remove the filter from the air cleaner,
push the tabs
Aand pull the cover up-
ward.
The viscous paper type filter element
should not be cleaned and reused. Replace
the air filter according to the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.
NOTE:
Af ter installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips
A.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information, refer to the

NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
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 “Recom-
mended fluids/lubricants and capaci-
ties” in the “Technical and consumer in-
formation” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belts*:Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
Engine coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with the proper mixture. (For
additional information on the proper mix-
ture 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
capacities” in the “Technical and consumer
information” section of this manual.
Engine valve clearance*: Inspect only if
valve noise increases. Adjust valve clear-
ance if necessary.
Evaporative emissions control vapor
lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place 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 immediately.
Brake pads and rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts immedi-
ately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
In-cabin microfilter: Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Propeller shaf t(s): Check for damage,
looseness, and grease leakage.

more frequent maintenance may be re-
quired.Af ter 120,000 miles
(192,000 km)/144 months, continue
maintenance at the same mileage/time
interval.

NOTE:
(1) Af ter 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. Af ter 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 0.053 in (1.35 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 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.
