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 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 within 1.5 seconds. (Emergency stop operation)
ECM Re-Communicating FunctionNIS0020F
Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, but only when the ECM has been replaced with a new one (*1).

NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS-IVIS/NVIS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
