REPLACING SPARK PLUGS
Iridium-tipped spark plugs (if so
equipped)
It is not necessary to replace iridium-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
iridium-tipped spark plugs by cleaning or regap-
ping.
● Always 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, see your NISSAN
dealer for assistance.
The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
log shown in the “NISSAN Service and Mainte-
nance Guide.” When replacing the filter, wipe the
inside of the air cleaner filter housing and the
cover with a damp cloth.
To remove the air cleaner filter, push the tabs

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.
