Unless each start condition is fulfilled, the engine will not response regardless of how many times the
push-button ignition switch is pushed. At that time, illumination repeats the position in the order of LOCK

→

ACC

→

ON

→

LOCK.

*1: When the A/T selector lever position is N position, the engine start condition is different according to the vehicle speed.

●

At vehicle speed of 5 km/h or less, the engine can start only when the brake pedal is depressed.

●

At vehicle speed of 5 km/h 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 A/T selector lever position is any position other than P position and when the vehicle speed is 5 km/h 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 the incorrect operation.)

●

Press the push-button ignition switch 3 times within 1.5 seconds. (Emergency stop operation)
