The ignition will return to the OFF mode.
If the gear selector is not in PARK (with vehicle stopped) and the ENGINE START/ STOP button is pushed once, the transmission will automatically select PARK and the engine will turn off while the ignition will remain in the ACC mode (NOT the OFF mode).

If the gear selector is in NEUTRAL, and the vehicle speed is below 5 mph (8 km/h), pushing the START/STOP button once will turn the engine off. The ignition will remain in the ACC mode.
