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.

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.
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: Tires should be rotated every
7,500 miles (12,000 km) according to the in-
structions under “Explanation of general
maintenance items” in this section. When
rotating tires, check for damage and un-
even wear. Replace if necessary.
Transmission fluid/oil, differential oil
and transfer case oil: Visually inspect for
signs of leakage at specified intervals.
If towing a trailer, using a camper or car-top
carrier, or driving on rough or muddy roads,
replace the CVT fluid every 60,000 miles
(96,000 km) or request the dealer to inspect
the fluid deterioration data using a CON-
SULT. If the deterioration data is more than
210000, replace the CVT fluid.
