If equipped with Integrated Keyhead Transmitter (IKT), if using a key in
the driver's door to unlock the vehicle, a chime will sound and the
message center will display TO STOP ALARM START VEHICLE when
you open the door. You will have 12 seconds to disarm the alarm system
using any of the actions above, otherwise the alarm will trigger.
