(1) When the selector lever position is in the N position, the engine start condition is different according to the vehicle speed.

  • At a vehicle speed of less than 4 km/h (2.5 MPH), the engine can start only when the brake pedal is depressed.
  • At a vehicle speed of 4 km/h (2.5 MPH) or more, the engine can start even if the brake pedal is not depressed. (It is the same as "Engine stall return operation while driving".)

(2) When the selector lever position is in any position other than the P position and when the vehicle speed is 5 km/h (3.1 MPH) or more, the engine stop condition is different.

  • Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short a time, the operation may be invalid, so properly press and hold to prevent an incorrect operation.)
  • Press the push-button ignition switch 3 times or more within 1.5 seconds. (Emergency stop operation)
