Delayed Locking

This feature delays the locking of the doors and the
liftgate when using the power lock or the remote keyless
entry system.
The first press of the power door lock switch or lock
button on the remote keyless entry transmitter with the
driver's door open will activate the delay locking. A chime
will sound. All doors and the liftgate can be reopened for
up to five seconds from the time the last door is closed.
Five seconds after the last door is closed, all the doors
will lock. You can lock the doors immediately by using
the power door lock switch or by pressing the lock button
on the optional remote keyless entry transmitter a
second time.
If the key is inserted in the ignition, this feature will not
lock the doors. See Lockout Protection on page 2-11.
You can turn the delayed locking feature on or off. If the
feature is turned off, the doors will lock immediately when
a power door lock switch or remote keyless entry
transmitter lock button is pressed.
