*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 in 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 or more within 1.5 seconds. (Emergency stop operation)
CAN Communication System DescriptionNIS001YA
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
