Your system allows you to add new remote controls in one step. (See
the Programming Table for Remote Controls section of this guide.)
If your vehicle battery is disconnected and later reconnected, the
system will automatically return to its last state before power was
removed, whether it was armed, disarmed, or in Valet Mode. For
example, if a mechanic were to disconnect the battery while the
alarm was disarmed or in Valet Mode, the alarm will not trigger
when the battery is reconnected. If power is removed and then
restored while the alarm is armed, the systems battery back up
siren will instantly sound and the indicator lights will flash.
