2006 Buick LaCrosse Owner's Manual - Page 86

Automatic Door Lock The vehicle's doors are programmed from the factory to lock when the shift lever is moved into a forward gear, and to unlock when the shift lever is moved into PARK (P). If someone needs to get in or out of the vehicle after the doors have been locked, place the shift lever into PARK (P). You may also unlock all doors using the power door lock switch or unlock one door using the inside manual door lock. If your vehicle has a Driver Information Center (DIC), there are different programming options for locking and unlocking the doors automatically. See DIC Vehicle Personalization on page 3-73. Rear Door Security Locks Your vehicle may have rear door security locks. These prevent passengers from opening the rear doors from the inside. The rear door security locks are located on the inside edge of each rear door. You must open the rear doors to access them. To set the locks, do the following: 1. Insert the key into the security lock slot and turn it so the slot is in the horizontal position. 2. Close the door. 2-12
