SPARK PLUGS 1. Visually inspect the belt for signs of unusual wear, 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 condition and tension in accordance with the maintenance schedule found in the "NISSAN Service and Maintenance Guide". 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. If replacement is required, see your NISSAN dealer for assistance.

Follow the maintenance log shown in the "NISSAN Service and Maintenance Guide". Do not service iridium-tipped spark plugs by cleaning or regapping. ● Always replace spark plugs with recommended or equivalent ones. 8-18 Maintenance and do-it-yourself
