1.PRECAUTIONS FOR PUSH-BUTTON START FUNCTION:

  1. Before starting the engine, firmly depress the brake pedal (or fully depress the clutch pedal) until the indicator in the engine switch turns green.

  2. The power source mode (off, on (ACC), on (IG)) is always retained in memory by the vehicle. If the battery is disconnected, the power source mode that was present before disconnection will be restored after the battery is reconnected. Be sure to turn the engine switch off before disconnecting the cable from the negative battery terminal. Be careful if the power source mode of a vehicle with a discharged battery is not known.

  3. After the battery is reconnected, be sure to wait 10 seconds or more before attempting to start the engine. The engine may not start immediately after the battery is reconnected.

  4. If the electrical key is held near the engine switch to start the engine when the electrical key battery is depleted, the following warnings will sound:

    1. A/T: Driver's door open → closed

      1. An exit warning will sound if the shift lever is in a position other than P and the power source is in a mode other than off.
      1. An exit warning will sound if the shift lever is in P and the power source is in a mode other than off.

    2. Doors other than the driver door open → closed

      1. A warning will sound to indicate that the electrical key has been taken out of the vehicle.
These warnings will sound because it is not possible for the vehicle to determine if the key is present in the vehicle (due to the depleted key battery). These warnings do not indicate system malfunctions.
