Auto re-lock function

• The auto re-lock function automatically locks the doors if any of the following operations are performed within 

approx. 30 s after the UNLOCK button of the card key is pressed, or after the request switch is pressed to 
unlock the doors.

— A door or the trunk lid is opened.

— The auxiliary key is inserted in the ignition key cylinder.

— The start knob is pressed.

— The transmitter (card key) is operated. (If the UNLOCK button is pressed, the timer is reset.)

— A request switch is operated.

Out-of-area (reception area) autolock function

• When all doors are closed and the driver is out of the reception area carrying the card key, the doors are 

automatically locked. (Initial setting is OFF.)

1. When all the following conditions are met and all doors are closed after any door or the trunk lid is open, the 

keyless beeper sound is heard and the function starts operation. (The doors are not locked at this time.)

— The card key is not inside the vehicle.

— The card key is within the reception area outside the vehicle.

— The auxiliary key is not inserted in the ignition key cylinder.

— The start knob is in the LOCK position, and not being pressed.

2. After the operation has started, the card key is monitored within the reception area by the keyless antenna. 

After about 2 s from where the card key has been determined to be out of the reception area, all lock actuators 
activate to lock. If approx. 30 s have passed since the operation started, the doors also locks regardless of 
whether the card key is within or out of the reception area.

3. The hazard warning light flashes once and keyless beep spund will be heard once at the same time the door 

locks.

ADVANCED KEYLESS START FUNCTION OPERATION

E5U091469000N03

• The advanced start function activates to start the engine by operating the start knob, and not by inserting the 

key but by the driver carrying the card key while in the vehicle.

1. When the start knob is pressed, the keyless control module sends a request signal from the keyless antennas 

(interior).

2. The card key receives the request signal, and sends back ID data.
3. The ID data is received by the keyless receiver, and sent to the keyless control module.
4. When the ID data is verified by the keyless control module and the card key is determined to be inside the 

vehicle, the start knob of the steering lock unit is released. The keyless indicator light (green) in the instrument 
cluster illuminates at the same time to indicate that the start knob is operable.

— If the ID verification is not acceptable (for reasons such as an unprogrammed card key, or card key battery 

depletion or transmitter interference), the start knob is not released and the keyless warning light (red) 
illuminates to indicate that the start knob is inoperable.

— For vehicles with the immobilizer system, ID verification is performed when the start knob is turned to the 

ON position, and if the verification is acceptable, permission is given to start the engine.

5. Turn the start knob to the START position to start the engine.

WARNING/GUIDANCE FUNCTION OPERATION

E5U091469000N04

• If the system is operated improperly, it warns the driver using the indicator light in the instrument cluster, buzzer 

sound, and keyless beeper in the trunk compartment.

• The operation condition of the advanced keyless system is indicated by the indicator light and beeper sound to 

guide user’s operation.

*1 : If the start knob is turned to the LOCK position with the card key out of the vehicle, the start knob is inoperable 

(the engine cannot be restarted). For vehicles with the immobilizer system, the engine cannot be restarted by 
turning the start knob from the ACC position to the START position even though the start knob has not been 
turned to the LOCK position.

*2 : Stops flashing and goes out if the card key is detected inside the vehicle.
*3 : Stops flashing and goes out if the card key is detected inside the vehicle and door is opened.

ON-BOARD DIAGNOSYS SYSTEM OUTLINE (ADVANCED KEYLESS ENTRY SYSTEM)

E5U091469000N06

Special Features

• The keyless entry system has an on-board diagnostic function to facilitate system diagnosis.

• The on-board diagnostic function consists of the following functions: a malfunction detection function, which 

detects overall malfunctions in the keyless entry system-related parts; a memory function, which stores 
detected DTCs; a display function, which indicates system malfunctions by DTC display; and a PID/data 
monitoring function, which reads out specific input/output signals.

• Using the WDS or equivalent, DTCs can be read out and cleared, and the PID/data monitoring function can be 

activated.
