WARNING
Be sure the engine and ignition
switch are off and that the parking
brake is applied.

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

9-6Maintenance and schedules
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.CHASSIS AND BODY MAINTENANCE
Brake lines and cables:
Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.
Brake pads and rotors:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or da-
maged parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deteriora-
tion, and damage. Tighten connections or
replace parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driv-
ing for prolonged periods in dusty condi-
tions, replace the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (AWD)
Steering gear and linkage, axle and
suspension parts, drive shaft boots:
Check for damage, looseness, and leak-
age of oil or grease. Under severe driving
conditions, inspect more frequently.
Tire rotation:
Tires should be rotated every 7,500 miles(12,000 km) according to the instructions
under “Explanation of general mainte-
nance items” (P.9-2). When rotating tires,
check for damage and uneven wear.
Replace if necessary.
Transmission fluid/oil, differential oil
and transfer case oil:
Visually inspect for signs of leakage at
specified intervals.
If using a car-top carrier, or driving on
rough or muddy roads:
.
Replace the Manual Transmission
gear oil every 20,000 miles (32,000
km) or 24 months.
. Replace the CVT fluid every 60,000
miles (96,000 km) or request the deal-
er to inspect the fluid deterioration
data using a CONSULT. If the dete-
rioration data is more than 210,000,
replace the CVT fluid.
