  3. How to turn off the ignition forcibly and to restart while driving
    • This method is used to stop the engine forcibly in the event of vehicle emergency (e.g. fuel leakage or unintended acceleration).
    • The engine is turned off and returns to ACC state if the button is long pressed for 2 seconds or pressed 3 times consecutively within 3 seconds while driving. For the next 30 seconds, restarting is possible regardless of the presence of FOB key inside the vehicle, and pressing the button without stepping on the brake (or with stepping on the brake) with FOB key inside the vehicle will change the electric power through OFF - ACC → IGN → OFF. (However, if gear is not in P, ACC ↔ AGN will be repeated. The conversion to OFF is impossible.)
