CHECK PUSH-BUTTON START FUNCTION

(a) Check the push-button start function:

(1) except Manual Transaxle:

Get into the vehicle while carrying the electrical key transmitter sub-assembly with the ignition switch off. With the shift position in P, check that the key indicator display is displayed when the brake pedal is depressed. Check that the engine starts when the engine switch is pressed after the key indicator display is displayed on the multi-information display.
While carrying the electrical key transmitter sub-assembly, check that the power source mode changes in the following order when the engine switch is pressed with the brake pedal released: off → ACC* → ON → off.
- *: When "ACC Customize" is set to "ON" using the multi-display
  HINT:
  
  If the engine switch is pressed with the ignition switch ON and the shift position not in P, the power source mode will not change to off, but to ACC.

(2) for Manual Transaxle:

Get into the vehicle while carrying the electrical key transmitter sub-assembly with the ignition switch off, check that the key indicator display is displayed when the clutch pedal is depressed. Check that the engine starts when the engine switch is pressed after the key indicator display is displayed on the multi-information display.
While carrying the electrical key transmitter sub-assembly, check that the power source mode changes in the following order when the engine switch is pressed with the clutch pedal released: off → ACC* → ON → off.
Check that the steering lock operates when a door is opened.
- *: When "ACC Customize" is set to "ON" using the multi-display

(3) Check the push-button start function operation range for the front side. Place the electrical key transmitter sub-assembly at either inspection point so that it is facing the direction shown in the illustration, and then check that the engine can be started.

NOTICE:

Even if the electrical key transmitter sub-assembly is in a vehicle interior detection area, it may not be properly detected if it is on the instrument panel, in the glove box or on the floor.

HINT:

Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (front floor).
