OPERATION DESCRIPTION

(a) Push-button start function:

(1) When the electrical key transmitter sub-assembly is in a vehicle interior detection area and the brake pedal is depressed, the engine is started by pressing the engine switch.

(2) When the electrical key transmitter sub-assembly is in a vehicle interior detection area and the brake pedal is not depressed, the power source mode is changed by pressing the engine switch. The power source mode changes in the following order every time the engine switch is pressed: off → on (ACC) → on (IG) → off.

(3) After getting into the vehicle while carrying the electrical key transmitter sub-assembly when the engine switch is off, if the engine switch is pressed while not depressing the brake pedal, the power source mode will change to on (ACC) and "ACCESSORY" will be displayed on the multi-information display.

Key Indicator Display

(6) The engine will start if the engine switch is pressed when the key indicator display is displayed.

(b) Changing the power source mode when the electrical key transmitter sub-assembly is not operating correctly due to wave interference or transmitter battery depletion:

(1) Unlock the door using the built-in mechanical key and get into the vehicle while carrying the electrical key transmitter sub-assembly.

(2) While depressing the brake pedal and facing the logo side of the electrical key transmitter sub-assembly toward the engine switch, hold the electrical key transmitter sub-assembly near the engine switch.

(3) A buzzer in the combination meter assembly will sound and the power source mode will change to on (IG) and "IGNITION ON" will be displayed on the multi-information display.

(4) Pressing the engine switch without depressing the brake pedal changes the power source mode from on (IG) to off.

(c) Starting the engine when the electrical key transmitter sub-assembly does not operate correctly due to wave interference or transmitter battery depletion:

(1) Unlock the door using the built-in mechanical key and get into the vehicle while carrying the electrical key transmitter sub-assembly.

(2) While depressing the brake pedal with the shift lever in P and facing the logo side of the electrical key transmitter sub-assembly toward the engine switch, hold the electrical key transmitter sub-assembly near the engine switch.

(4) Press the engine switch with the brake pedal depressed to start the engine.

CHECK PUSH-BUTTON START FUNCTION

(a) Check the push-button start function:

(1) Get into the vehicle while carrying the electrical key transmitter sub-assembly with the engine switch off. With the shift lever 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.

(2) 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 → on (ACC) → on (IG) → off.

HINT:

If the engine switch is pressed with the engine switch on (IG) and the shift lever not in P, the power source mode will not change to off, but to on (ACC).

(3) With the shift lever in P, check that the steering lock operates when a door is opened.

HINT:

When the engine switch is pressed after the vehicle is stopped, the engine will stop and all power will turn off. However, if the shift lever is not in P when the engine switch is pressed with the vehicle stopped, the power source mode will not change to off, but to on (ACC).

(4) 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).
