The 4th position is START, the setting that engages the starter motor to crank the engine. In most Honda cars and motorcycles, ignition switches use four positions: LOCK (or OFF), ACCESSORY, ON, and START.
Understanding how Honda ignition switches work helps drivers and riders operate their vehicles safely and efficiently. While the exact labeling can vary by model and market, the four-position framework is widely used across Honda’s lineup.
Common ignition switch positions and their functions
Below is a quick rundown of the four common ignition switch positions and their functions on Honda vehicles and motorcycles.
- LOCK (or OFF) — Locks the steering column and powers down the ignition; used when the vehicle is parked and secured.
- ACCESSORY (ACC) — Provides power to certain accessories (radio, charging ports) without starting the engine.
- ON (RUN) — Powers the engine management system and most electrical components; the vehicle is ready to start.
- START — Activates the starter motor to crank the engine; releasing the key returns the switch to ON.
The START position is designed for brief use to initialize engine cranking. Prolonged use in START without releasing the key can drain the battery or cause starter wear.
Model-specific notes
While the 4th position is typically START across Honda cars and motorcycles, there can be variations by model, year, and market. Always refer to the owner’s manual for your exact model to confirm the sequence and safe operating procedures.
By vehicle type, Honda generally aligns with a LOCK/OFF → ACC → ON → START progression in many cars, and a similar pattern in motorcycles and scooters, though some models use subtle naming differences (for example, LOCK vs. OFF or ACC vs. ACCESSORY). Always verify with model-specific documentation.
Summary
Across Honda’s lineup, the fourth ignition switch position is typically the START setting, which engages the starter motor to crank the engine. If you’re unsure for a particular model or year, consult the owner’s manual or contact a Honda dealer to confirm the exact sequence and any safety notes.
