Keep the battery surface clean and dry. Any
corrosion should be washed off with a solu-
tion of baking soda and water.

Make certain the terminal connections are
clean and securely tightened.

If the vehicle is not to be used for 30 days or
longer, disconnect the (—) negative battery
terminal cable to prevent discharging it.
WARNING

Do not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15 min-
utes and seek medical attention.

Do not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-tery which can generate heat, reduce
battery life, and in some cases lead
to an explosion.

When working on or near a battery,
always wear suitable eye protection
and remove all jewelry.

Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.

Keep the battery out of the reach of
children.
Check the fluid level in each cell. It should be
between the MAX and MIN lines.
If the side of the battery is not visible, the
electrolyte level can be checked through each
filler opening as illustrated.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
1. Remove the cell plugs.
2. Add distilled water up to the MAX level.
3. Tighten cell 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.
REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance schedule but, do not
reuse them by cleaning or regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, push
down the lock pins
1
and pull the unit upward
2.
The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the separate Service and Mainte-
nance Guide. When replacing the filter, wipe the
inside of the air cleaner housing and the cover
with a damp cloth.
