WARNING
Be sure the ignition key is in the OFF or
LOCK position. The engine could rotate
unexpectedly.
1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying, oil adhesion or
looseness. If the belt is in poor condition or
loose, have it replaced or adjusted by your
NISSAN dealer.
2. Have the belts checked regularly for condi-tion and tension in accordance with the
maintenance schedule in this manual.
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
remove the spark plugs. An incorrect
socket can damage the spark plugs.

REPLACING SPARK PLUGS1. Remove the rocker cover ornament using a
suitable hexagon socket. (Front side)
2. Disconnect the electrical connectors.
3. Loosen the ignition coil fixing bolts. And
remove the ignition coil to give access to
the spark plugs.
4. Remove the spark plugs with a spark plug
socket.
The plug socket has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that eachspark plug is snugly fitted into the plug
socket.
5. Fit the new plugs, one at a time, into the
spark plug socket and install them. Turn
each plug in several full turns by hand, then
tighten with a spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 N×m)6. Holding the ignition coil, re-connect each
ignition coil to its proper spark plug by
pushing it on until you feel a snap.
7. Tighten all ignition coils.

Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See ªPeriodic maintenance
schedulesº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
IOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner

EXPLANATION OF MAINTENANCE
ITEMSAdditional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.Emission control system
maintenanceDrive belts*:Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter:Under normal driving con-
ditions, 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.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines:Check EVAP vapor lines
and connections for failure or looseness. If
leaks are found, replace them.
Fuel lines:Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*:Drain and flush the cooling
system.
Engine oil & oil filter*:Under normal drivingconditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*:Replace with new plugs having
the correct heat range.
Intake & exhaust valve clearance:Check the
valve clearance if valve noise increases.
Chassis and body maintenanceBrake lines & cables:Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: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 transaxle oil & automatic transaxle
fluid*:Check the fluid level and visually in-
spect for signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts, and front drive shaft boots:Check fordamage, looseness and leakage of oil or
grease. Under severe driving conditions, they
may have to be inspected more frequently.
Exhaust system:Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
Supplemental air bag, and supplemental
side air bag (if so equipped) systems:Main-
tenance 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 (be-
tween ASCD actuator and ASCD pump) for
breakage, cracks or fracture.
