1. Visually inspect the belt for signs of unusualwear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted by a NISSAN dealer.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in the
“NISSAN Service and Maintenance Guide”.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
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 a NISSAN dealer
for assistance.
