NOTE: (1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 30,000 miles(48,000 km)
or 24 months except for LSD. Change LSD gear oil every 15,000 miles (24,000 km) or 12 months.
(2) The propeller shaft should be re-greased after being immersed in water.
(3) If operating frequently in water, replace grease every 3,750 miles (6,000 km) or 3 months.
(4) Inspect the supplemental air bag system 10 years after the date of manufacture noted on the F.M.V.S.S. certification label.

Emission control system
maintenanceAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.
Drive belts*:
Check drive belts for wear, fraying or cracking
and also for proper tension. Replace the drive
belts if found damaged.
Air filter:
Under normal driving conditions, the air
cleaner filter should be replaced in accordance
with the maintenance schedule. However,
driving the vehicle in dusty areas may cause
more rapid clogging of the element. Conse-
quently, the element may have to be replaced
more frequently.
EVAP vapor lines:
Check vapor lines and connections for failure
or looseness. If leaks are found, replace the
lines.
Fuel lines:
Check the fuel hoses, piping and connections
for leaks, looseness or deterioration. Replace
any parts if they are damaged.Fuel filter:
If the vehicle is operated under extremely
adverse weather conditions or in areas where
ambient temperatures are either extremely low
or extremely high, the filter might become
clogged. In such an event, replace the filter
immediately.
Engine coolant*:
Flush and refill the cooling system.
Engine oil & oil filter*:
Under normal driving conditions, the engine oil
and oil filter should be replaced in accordance
with the maintenance schedule. However, un-
der severe driving conditions, they may have
to be replaced more frequently.
Spark plugs*:
Replace with new plugs having the correct
heat range.
Timing belt:
Replace the timing belt for driving the cam-
shafts.
Chassis and body maintenanceBrake lines & cables:
Check the brake lines and hoses (including
brake booster vacuum hoses, connections &
check valve) and parking brake cables for
proper attachment, leaks, cracks, chafing,
abrasion, deterioration, etc.
Brake pads, rotors, drums & linings:
Check these and the other neighboring brake
components for wear, deterioration and leaks.
Under severe driving conditions, they may
have to be inspected more frequently.
Manual and automatic transmission,
transfer & differential gear fluid:
Visually inspect for signs of leakage and re-
place oil for limited-slip differential. Under se-
vere driving conditions, the oil should be re-
placed at the specified interval.
Steering gear, linkage & transfer gear,
axle & suspension parts & drive axle
shaft boots:
Check for damage, looseness and leakage of
oil or grease. Under severe driving conditions,
more frequent inspection should be per-
formed.

Propeller shaft(s):
Check the propeller shaft(s) for damage,
looseness and grease leakage under severe
driving condition (
only).
Propeller shaft:
Apply specified grease to the greasing points
of propeller shafts in accordance with the
maintenance schedule. In the case of driving
in water, greasing should be performed imme-
diately afterwards.
Front wheel bearing grease:
Check the wheel bearing for grease leakage
around grease seals, axial end play and
smooth turning (4x2).
Check the wheel bearing grease condition or
repack these in accordance with the mainte-
nance schedule. In case of frequent driving in
muddy water, the bearing grease inspection
should be performed more frequently (
).
Exhaust system:
Visually check the exhaust pipes, muffler, and
hangers for proper attachment, leaks, cracks,
chafing, abrasion, deterioration, etc. Under
severe driving conditions, inspection should be
performed more frequently.Supplemental air bag, and supplemental
side air bag (if so equipped) systems:
Maintenance for the supplemental air bags or
supplemental side air bags should be done by
an authorized NISSAN dealer.
Automatic Speed Control Device (ASCD)
vacuum hoses:
Check vacuum hose (between ASCD actuator
and ASCD pump) for breakage, cracks or
fracture.
