Delayed Locking
This feature allows the driver to delay the actual locking
of the doors. When the driver power door lock switch is
pressed with the key removed from the ignition, and the
driver 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 or passenger power door lock switch
again or the remote keyless entry transmitter button
will override this feature.
Personal Choice Programming
The delayed locking feature can be turned on or off,
using the Driver Information Center (DIC) to program
this feature. See “DELAY DOOR LOCK” underDIC
Vehicle Customization on page 3-66.
Programmable Automatic Door
Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on, and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have the person use the manual lock knob or
power door lock switch. When the door is closed again, it
will not lock automatically. Use the manual lock knob or
power door lock switch to lock the door.
If your vehicle has a Driver Information Center (DIC),
you can choose various lock and unlock settings.

Customization on page 3-66.
