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 con- dition 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
OAspark 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.

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, see “Recom-
mended fluids/lubricants and capaci-
ties” (P. 10-2).
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, see “Engine cooling sys-
tem” (P. 8-5).
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,
see “Recommended fluids/lubricants and
capacities” (P. 10-2).
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 filter: Periodic maintenance is not re-
quired. (in-tank type filter)
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
immediately.
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.
9-6Maintenance and schedules

Severe use maintenance:
Inspections:
• Brake pads and rotors
• Exhaust system
• Drive shaf t boots
• Propeller shaf t (4WD models)
• Steering gear and linkage, axle and sus-pension parts
Essential:
• Replace brake fluid
• Replace differential gear oil
• Replace transfer fluid
* Maintenance items and intervals with “*”
are recommended by NISSAN for reliable
vehicle operation. The owner need not per-

within two weeks or less than 500 miles
(800 km).105,000 miles/(168,000 km)/
126 months
Perform at number of miles, kilometers or
months, whichever comes first.
Standard maintenance:
Essential:
• Replace in-cabin microfilter
• Replace Intelligent Key battery
• Replace spark plugs (6)(7)
• Replace engine coolant* (3)(4)
Severe use maintenance:
Inspections:
• Brake pads and rotors
• Exhaust system
• Drive shaf t boots
• Propeller shaf t (4WD models)
• Steering gear and linkage, axle and sus- pension parts
(6) Performed based on the number of
miles only.
(7) Replace spark plug when the plug gap
exceeds 0.053 in (1.35 mm) even if within
specified replacement mileage. (3) 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.
