your vehicle. If you hear a second chirp after arming, and see the
status LED flashing in groups, refer to the Diagnostics section of
this guide. This extra chirp is called Bypass Notification.
The system also can be programmed to arm itself automatically
(called passive arming). If the system is programmed for passive
arming, it will automatically arm 30 seconds after the ignition is
turned off and the system "sees" you leave the vehicle by opening
and closing a door. Whenever the system is in its 30-second pas-
sive-arming countdown, the status LED will flash twice as fast as
it does when the system is armed. The siren will chirp one time 20
seconds after the last door has been closed. The system is not
actually armed at that point. The system arms and the doors lock
(if connected and programmed for passive locking) at the 30 sec-
ond mark, but the siren will not chirp. The early chirp provides you
with a 10-second warning prior to arming.
NOTE: If any protected entry point (such as a door or a switch-protected
trunk or hood) is open, the system will not passively arm (unless forced
passive arming is programmed on.) See Programming Options section of
this guide. Additionally, each time a sensor is triggered during the arm-
ing countdown, the 30-second countdown starts over.
When armed, your vehicle is protected as follows:
■ Light impacts will trigger the Warn Away ® signal. When trig-
gered, the siren will chirp and the parking lights will flash for
a few seconds.
■ Heavy impacts will trigger the system. The triggered sequence is
between 1-180 seconds of constant siren and flashing parking
lights.
