Delayed Locking

This feature allows the driver to delay the actual
locking of the doors. When the driver's power door
lock switch or remote keyless entry transmitter lock
button is pressed with the key removed from the
ignition, and the driver's door open, a chime will
sound three times to signal that the delayed locking
system is active. When all doors have been closed,
the doors will lock automatically after several
seconds. If any door is opened before this, the timer
will reset itself once all the doors have been closed
again.
Pressing the driver's or passenger's power door
lock switch or the remote keyless entry transmitter
button again will override this feature.
