Theft-Deterrent Arming Verification Your vehicle comes with this feature set in Mode 3. This means that if you arm the system using the key chain transmitter, your parking lamps will flash and your horn will chirp twice to verify that the system is armed. If it only chirps once, the hatch is open or unlatched. If you arm the system using either the power door lock switch or by passive arming, only the parking lamps will flash for verification. To change the factory setting, do the following: 1. Press the LOCK switch on the key chain transmitter. Mode 1: All Off (No horn chirps or parking lamp flash). Mode 2: Horn and Lamps (Your parking lamps will flash and your horn will chirp twice to verify the system is armed using any arming method). Mode 3: Horn and Lamps/Lamps (If you use the key chain transmitter to arm the system, your parking lamps will flash and your horn will chirp twice to verify that the system is armed. If you use either the power door lock switch or passive arming, only your lamps will flash for verification). Mode 4: Lamps (When your vehicle arms, only your parking lamps will flash for verification). 2. Count the number of chimes you hear. The number of chimes tells you which mode your vehicle is set for. 3. Press the LOCK switch on the key chain transmitter until you hear the number of chimes that correspond to the mode selection you want. 2-21
