1. Visually inspect the belt for signs of un-usual wear, cuts, or fraying. If the belt is
in poor condition, have it replaced or
adjusted. It is recommended that you
visit a NISSAN dealer for this service.
2. Have the belt checked regularly for condition.
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.

SPARK PLUGS
8-14Do-it-yourself

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 re-
duce 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.
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 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 deteriorated or damaged
parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or dam-
aged 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.
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
5,000 miles (8,000 km) according to the in-
structions under “General maintenance” in
this section. When rotating tires, check for
damage and uneven wear. Replace if nec-
essary. Transmission fluid/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 CVT
fluid every 60,000 miles (96,000 km) or re-
quest the dealer to inspect the fluid dete-
rioration data using a CONSULT. If the dete-
rioration data is more than 210000, replace
the CVT fluid.
9-6Maintenance and schedules

The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions,
varying road surfaces, individual driving
habits and vehicle usage, additional or
more frequent maintenance may be re-
quired.Af ter 120,000 miles
(192,000 km)/144 months, continue
maintenance at the same mileage/time
interval.

NOTE:
(1) Af ter 40,000 miles (64,000 km) or 48 months, inspect every 10,000 miles (16,000 km) or 12 months. Replace the drive belt if
found damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item.
(4) 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.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy
of the factory fill coolant.
(6) Replace spark plug when the plug exceeds 1.35 mm (0.053 in) even if within specified periodic replacement mileage.
(7) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
*: Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not
perform such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items
and intervals are required.
