2. Have the belts checked regularly for condi-
tion and tension in accordance with the
maintenance schedule found in the
“NISSAN Service and Maintenance Guide”.
REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-tipped
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance schedule, but do not reuse
the spark plugs by cleaning or regapping.
cAlways 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, please see your
NISSAN dealer for assistance.
