  • Press the "UNLOCK/DISARM" button on the transmitter momentarily once again within five seconds and check if all the doors including the rear gate on wagon are unlocked.
  • Press the "LOCK/ARM" button on the transmitter a little bit of time (approx. 2 sec.) and check if a panicking condition occurs; the horn sounds continuously, the hazard lights flash and the security indicator light flashes rapidly. Also, check if that condition lasts for 30 seconds or until any button of the transmitter is pressed.

    Press the "LOCK/ARM" button on the transmitter momentarily once with one of the doors including the rear gate open and check if the buzzer chirps five times to warn of a door ajar. Then, bring all the doors including the rear gate in closed condition and check if the arming condition is brought about; all the doors are locked, the buzzer chirps once and the hazard lights flash once.

  • Press the "LOCK" side of the power door locking switch with any one of the doors including the rear gate open. Then, bring all the doors including the rear gate in the closed condition and check if all the doors are locked, the buzzer chirps once and the hazard lights flash once to ensure that the security system has been brought into the arming state.

  • Unlock a door using the inner lock knob or the key and open the door while the security system is in the arming state. Check to ensure that the alarming condition occurs, i.e. the horn sounds continuously, the hazard lights flash and security indicator light flashes rapidly, and that it lasts for 30 seconds or until the "UNLOCK/DISARM" button on the transmitter is pressed. Also, check to ensure that turning the ignition key to the "START" position in the arming state does not cause the starter motor to turn, thus the engine being prevented from starting.
  • Strike the windshield with a hand with the security system in arming state, and check to ensure that the alarming condition occurs.
  • Troubleshoot the security system if any one of the above-mentioned checks does not meet the requirements.
