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 discharge.
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.

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.

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.
JUMP STARTINGIf jump starting is necessary, see “Jump starting”
in the “6. In case of emergency” section. If the
engine does not start by jump starting, the
battery may have to be replaced. Contact your
NISSAN dealer.Check the fluid level in each cell. It should be
between the MAX. and MIN. lines.
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.
1. Remove the cell plugs using a suitable tool.
2. Add distilled water up to the MAX. level.
If the side of the battery is not visible, the
electrolyte level can be checked through
each filler opening as illustrated.
3. Tighten cell plugs.

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 toremove the spark plugs. An incorrect
socket can cause damage the spark
plugs.
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the conven-
tional 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.
The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance log shown in a separate “Service
and Maintenance Guide”. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
