Programmable Automatic Door Locks; Rear Door Security Locks - Buick 2011 Lucerne Owner's Manual

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 P (Park), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever into P (Park).
If someone needs to get out while your vehicle is not in
P (Park), 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. For
programming information, see DIC Vehicle
Customization on page 4 56.
