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. Press the customization button until DELAY DOOR LOCK appears on the DIC display. Press the set/reset button once to access the settings for this feature. Then press the customization button to scroll through the following settings: OFF: There will be no delayed locking of the vehicle's doors. ON (default): The doors will not lock until five seconds after the last door is closed. NO CHANGE: No change will be made to this feature. The current setting will remain. To select a setting, press the set/reset button while the desired setting is displayed on the DIC.
