4. BUZZER SOUND FUNCTION
During lock operation, when the wireless door lock ECU receives a lock signal from the door unlock detection SW, the wireless door lock buzzer goes on once. During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection SW, the keyless buzzer goes on twice.

With any door open, when the wireless door lock ECU receives a lock signal from the transmitter, the keyless buzzer goes on for approx. 10 seconds. If the door is closed, or ignition SW is on, or if the unlock signal is received from the transmitter while the buzzer is on, the buzzer stops.

5. VISUAL CONFIRMATION OF LOCK OR UNLOCK

During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection SW, the taillight and front parking light is flashed twice.

6. PANIC MODE FUNCTION
When the lock switch on the transmitter is kept pressed for approximately 2.5 sec., the wireless door lock ECU receives the signal and enters the panic mode. The theft alarm goes on upon receiving the signal, and the headlights and taillights flash. At this time, when any SW on the transmitter is pressed, the panic mode is cancelled, the theft alarm is stopped, and the headlights and taillights go off.

7. REPEAT FUNCTION
If the lock detection signal in response to the output signal is not received after the wireless door lock ECU has output the lock signal, the lock signal is output again.

6. POWER SLIDE DOOR FUNCTION
The power slide door can be opened/closed by operating the left power door SW or right power door SW on the transmitter.
