SPARK PLUG CONSTRUCTION [LF]

E5U011818110N01

• An iridium spark plug with excellent durability and 

firing performance has been adopted.

• The extremely thin, center electrode has a 

diameter of 0.6 mm {0.024 in} and is made of 
iridium alloy.

• Durability has been improved by the use of a 

platinum-tipped grounding electrode.

• Based on the thinner electrode (center electrode), 

electric discharge has been reduced and ignition 
has been improved, resulting in stable ignition 
performance under all driving conditions.

STARTER INTERLOCK SWITCH CONSTRUCTION/OPERATION [MT]

E5U011943440N01

Construction

• The starter interlock switch mechanism prevents vehicle surge when the engine is started, enhancing the 

safety. The engine cannot be started unless the clutch is depressed.

• The mechanism is provided with a starter interlock switch on the circuit between the ignition switch and the 

starter.

Operation

• Depressing the clutch pedal presses the starter interlock switch rod. At this time, the starter interlock switch is 

on, and the power circuit to starter closes. Accordingly, the starter operates only when the clutch is depressed 
whereby the engine can be started.
