unexpectedly.
1. Visually inspect each belt for signs of unusual
wear, cuts, fraying, oil adhesion or looseness.
If the belt is in poor condition or loose, have
it replaced or adjusted by a NISSAN dealer.
2. Have the belts checked regularly for condi-
tion.
REPLACING SPARK PLUGSIf replacement is required, see a NISSAN dealer
for servicing.
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
remove the spark plugs. An incorrect
socket can damage the spark plugs.
Iridium-tipped spark plugsIt is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance log shown in the
“NISSAN Service and Maintenance Guide”, but
do not service iridium-tipped spark plugs by
cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
