WARNING
Be sure the ignition switch is in the OFF
or LOCK position before servicing 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 con- dition and tension in accordance with
the maintenance schedule. For addi-
tional information, see the "Mainte-
nance and schedules" section of this
manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped spark 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.

MAINTENANCE:
Engine 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 in-
tervals. 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. 8-7)).
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 ca-
pacities” (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 Lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
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.
(4WD/RWD).
Steering Gear and Linkage, Axle and Sus-
pension Parts, Drive Shaf t Boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire Rotation: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
Transmission Fluid/Oil, Differential Gear
Oil, Transfer Case Oil: Visually inspect for
signs of leakage at specified intervals.
Replace automatic transmission fluid at
specified intervals.
If towing a trailer, using a camper or car-top
carrier, or driving on rough or muddy roads:
• Replace the differential oil every 20,000 miles (32,000 km) or 24 months.
• Replace the automatic transmission fluid ever 30,000 miles (48,000 km) or 24
months.
