2. Check the fluid level in each cell.
If it is necessary to add fluid, add only
distilled water to bring the level up to the
OK level indicator in each filler opening.
Do not overfill.
JUMP STARTING
If jump starting is necessary, see the ``In
case of emergency'' section of this owner's
manual. If the engine does not start by jump
starting, the battery may have to be re-
placed. Contact an authorized NISSAN
dealer.
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
unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or is loose,
have it replaced or adjusted by an autho-
rized NISSAN dealer.
2. Have the belts checked regularly for con-
dition and tension in accordance with the
maintenance schedule found in the
``Maintenance'' section of this manual.REPLACING SPARK PLUGS
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.

Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.
1. Remove brackets as necessary to give
access to the high tension spark plug
cables and spark plugs.2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so it does not fall
when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.
4. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 Nzm)
5. Holding the boot, reconnect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.
6. Reinstall all brackets as necessary.The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the ``Main-
tenance'' section of this manual. When re-
placing the filter, wipe the inside of the air
cleaner filter housing and the cover with a
damp cloth.

EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items marked with an ``*'' is found in the
``Do-it- yourself'' section of this manual.
Emission control system
maintenance
Drive belts* ÐCheck drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filter ÐUnder normal driving
conditions, the air cleaner filter should be
replaced in accordance with the mainte-
nance schedule. However, driving the ve-
hicle in dusty areas may cause rapid clog-
ging of the element. Consequently, the
element may have to be replaced more
frequently.
EVAP vapor lines ÐCheck vapor lines
and connections for leaks, looseness or
deterioration. If leaks are found, replace
them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any damaged parts.Fuel filter ÐIf the vehicle is operated
under extremely adverse weather condi-
tions or in areas where ambient tempera-
tures are either extremely low or extremely
high, the filter might become clogged. In
such an event, replace the filter immedi-
ately.
Engine coolant* ÐDrain and flush the
cooling system.
Engine oil & oil filter* ÐUnder normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs* ÐReplace with new plugs
having the correct heat range.
Intake & exhaust valve clearance Ð
Check the valve clearance if valve noise
increases.
Chassis and body maintenance
Brake lines & cables ÐCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, rotors, drums & linings Ð
Check these and the other neighboring
brake components for wear, deterioration
and leaks. Under severe driving conditions,
they may have to be inspected more fre-
quently.
Manual & automatic transmission fluid*
ÐCheck the fluid level and visually inspect
for signs of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft boots Ð
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, inspection should be performed
more frequently.
Exhaust system ÐVisually check the ex-
haust pipes, muffler, and hangers for proper
attachment, leaks, cracks, chafing, abra-
sion, deterioration, etc. Under severe driv-
ing conditions, inspection should be per-
formed more frequently.
