The power supply position changing operation can be performed with the following operations.

NOTE:

When an Intelligent Key is within the detection area of inside key antenna and when it is inserted to the key slot, it is equivalent to the operations below.
When starting the engine, the BCM monitors under the engine start conditions,
A/T models
- Brake pedal operating condition
- A/T selector lever position
- Vehicle speed
  M/T models
- Clutch pedal operating condition
- Vehicle speed
Unless each start condition is fulfilled, the engine will not respond regardless of how many times the engine switch is pressed. At that time, illumination repeats the position in the order of LOCK→ACC→ON→OFF.

N position

⁽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 less than 4 km/h (2.5 MPH), the engine can start only when the brake pedal is depressed.
At 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 A/T selector lever position is in any position other than 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)

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
