DELAY DOOR LOCK
On vehicles with a crew cab, this feature allows you to
select whether or not the locking of the vehicle's doors
will be delayed. When locking the doors with the power
door lock switch and a door is open, this feature will delay
locking the doors until five seconds after the last door is
closed. You will hear three chimes to signal that the
delayed locking feature is in use. The key must be out of
the ignition for this feature to work. You can temporarily
override delayed locking by pressing the power door lock
switch twice or the lock button on the RKE transmitter
twice. See Delayed Locking on page 2-11 for more
information.

LOCK appears on the DIC display. Press the set/reset
button once to access the settings for this feature.

the following settings:
OFF: There will be no delayed locking of the
vehicle's doors.
