Theft-Deterrent Arming Verification
Your vehicle comes with the theft
verification set in Mode 3. This means that if you arm
the system using the keyless entry transmitter, your
headlamps and parking lamps will flash and your horn
will chirp twice to verify that the system is armed. If it
only chirps once, the tailgate or the panel doors are open
or unlatched. In addition, if the system did not arm, the
horn will chirp once and the theft
the center floor console will not flash. If you arm the
system using either the power door lock switch or by
passive arming, only the headlamps and parking lamps
will flash for verification. To change the factory setting,
do the following:
1. Press the LOCK switch on the keyless
entry transmitter.
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 keyless entry
transmitter until you hear the number of chimes that
corresponds to the mode selection you want.
