Remote Transmitter Lock/Unlock Control - Unlock
The remote transmitter feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The remote
transmitter feature provides a 2-step process for unlocking the doors. Upon receipt of the first requests for unlocking the doors, the remote control
feature requests the vehicle security module to unlock the driver door only. If another unlock request is received within 3 seconds of the first, the
remote transmitter feature will request that all doors be unlocked.
Remote Transmitter Lock/Unlock Control - Lock
The remote transmitter feature requests that all the doors be locked when the door lock control switch LOCK button is pressed. On any press of the
LOCK button with all doors closed, the remote transmitter feature requests one flash of the parking lamps. If any door is ajar, no flash will occur,
indicating it locked all the doors but one or more doors are ajar. As soon as the last door is closed, the vehicle provides the one flash of the parking
lamps. If 2 presses of the LOCK button are received within 3 seconds the horn chirps once, and the parking lamps flash twice to indicate that all the
doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the remote transmitter feature
requests the horn chirp twice without flashing the parking lamps to indicate it locked all the doors but one or more doors are ajar. When the key is in
the ON or START position, no parking lamp flashes or horn chirp confirmations occur.
PANIC ALARM
The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that
the parking lamps are flashed and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. Activation of the panic alarm
is accomplished by pressing the PANIC button on a remote transmitter whenever the key is in the OFF or ACC positions. At all other times this
feature is disabled. Deactivation of an active PANIC alarm is accomplished by: 1) a second press of the remote transmitter PANIC button, 2) the key
is switched out of the OFF or ACC position, or 3) a period of 2 minutes and 45 seconds has elapsed since the initial activation.
