SECURITY AND LOCKS [ADVANCED KEYLESS SYSTEM]
ADVANCED KEYLESS START FUNCTION OPERATION
• 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.
