VEHICLE SECURITY ALARM
The Vehicle Security Alarm monitors the vehicle doors
and ignition for unauthorized operation. When the Ve-
hicle Security Alarm is activated, interior switches for
door locks are disabled. The system provides both au-
dible and visible signals for the first three minutes the
horn will sound and the headlights will turn on, the park
lamps and/or turn signals will flash and Vehicle Security
Light will flash repeatedly. For an additional 15 minutes
only, the headlights will turn on, the park lamps and/or
turn signals, and Vehicle Security Light will flash.
Rearming Of The System
The Vehicle Security Alarm will rearm itself after the 15
additional minutes of headlights and Vehicle Security
Light flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
