WARNING
Be sure the ignition switch is placed in
the OFF or LOCK position before servic-
ing 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 found in the
"Maintenance and schedules" section of
this manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
OAspark 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. The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance log shown in the "Mainte-
nance and schedules" section of this
manual.
To remove the air cleaner filter:
1. Unlatch the retaining clips
OA.
2. Move the air cleaner cover upwards.
3. Remove the air cleaner filter. Wipe the inside of the air cleaner filter housing
and the cover with a damp cloth, then
replace air cleaner filter.
NOTE:
Af ter installing a new air cleaner filter,
make sure the air cleaner cover is seated
in the housing and latch the clips.
WARNING
• Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn't
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful when working on the engine with
the air cleaner removed.
• Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.

NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capaci-
ties” (P. 10-2).
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belt*:Check engine drive belt for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belt.
Engine air filter: Replace at specified inter-
vals. 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. 8-4).
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 increase. Adjust valve clearance
if necessary.
Evaporative emissions control vapor
lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel filter*: Periodic maintenance is not re-
quired. (in-tank type filter)
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
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. (AWD)
