If the RKE transmitter "LOCK" or "UNLOCK" switch is pressed while the ignition key is removed, the doors can be locked or unlocked. If the doors are closed, the hazard warning lights, the interior lights and the horn will operate due to answerback function. Because of the answerback function, the hazard warning lights flash twice, and the horn sounds once, the interior lights flash twice when the doors are locked. Meanwhile, when the doors are unlocked, the hazard warning lights flash and the interior lights illuminate for 30 seconds. The hazard and the horn answerback functions can be cancelled by using the transmitter.
