1. Visually inspect the belt for signs of un-usual wear, cuts, fraying or looseness. If
the belt is in poor condition or is loose,
have it replaced or adjusted. It is recom-
mended that you visit a NISSAN dealer
for this service.
2. Have the belt checked regularly for con- dition and tension in accordance with
the maintenance schedule. For addi-
tional information, refer to the "Mainte-
nance and schedules" section of this
manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped spark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
•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, it is recom-
mended that you visit a NISSAN dealer for
this service.
