Lincoln Navigator: Perimeter Anti-Theft Alarm / Perimeter Anti-Theft Alarm - Overview. Description and Operation

Overview

The perimeter anti-theft alarm system has three operation modes:

• ARMED - The perimeter anti-theft alarm is armed when the ignition is OFF and all vehicle entry points have been electrically locked for 20 seconds.
• ACTIVE - When the perimeter anti-theft alarm activates, the horn sounds and all turn signals and interior courtesy lamps flash. The horn stops sounding after 30 seconds and the lights continue to flash for up to 5 minutes.
• DISARMED - The perimeter anti-theft alarm is disarmed when a vehicle entry point is open or unlocked, or if the ignition is ON.

The panic alarm operates similar to the perimeter alarm, but only activates when the ignition is OFF and the RKE transmitter panic button is used. For additional information of the panic alarm function,
