REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-tippedA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
platinum-tipped spark plugs by cleaning or re-
gapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.

Replace the air cleaner filter according to the
maintenance log shown in the “Warranty Informa-
tion and Maintenance Booklet.”
To remove the air cleaner filter:● Unlatch the clips and move the air cleaner
cover upward.
● Remove the air cleaner filter.
● Wipe the inside of the air cleaner filter hous-
ing and the cover with a damp cloth. NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips.
WARNING
●
Operating the engine with the air
cleaner removed can cause you or oth-
ers to be burned. The air cleaner not
only cleans the air, it stops the flame if
the engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
