Security Feedback
Security Feedback provides audible and/or visible
feedback that a remote keyless entry lock or unlock
command has been received and executed. Your
vehicle's ignition must be off for this feature to work.
You may select one of four operating modes for
reception of a lock command. You may also select one
of four operating modes for reception of an unlock
command. The selection and programming of the lock
and unlock operating modes are independent of each
other. The following modes are available for either lock
or unlock verification:
Mode 1 : No Verification
Mode 2: Horn Chirp only
Mode 3: Headlamp Flash only
Mode 4:Horn Chirp and Headlamp Flash
The operating mode of the Security Feedback lock
feature will be changed when you perform the following
sequence with your vehicle's doors closed and the
ignition key in RUN:
1. Press and hold the power door lock switch. While
holding the door lock switch, press and release the
remote keyless entry
(RKE)
transmitter
lock
switch.
2. This will initialize the customization mode. While in
the customization mode, the feature will sound the
number of chimes corresponding to the current
Security Feedback lock mode.
Each additional press of the RKE transmitter lock button
will cause your vehicle to advance the lock mode by
one, starting from the current lock mode. If cycled
beyond lock Mode 4, the vehicle will enter lock Mode 1.
During this procedure, the feature will sound the number
of chimes corresponding to the current lock mode,
providing you with feedback. When the door lock
switch is released, the vehicle will remain in the most
recent lock mode.
