2004 Buick Century Owner's Manual - Page 78

The vehicle was originally programmed to Mode 3. The mode may have been changed since then. To determine the current mode, or to change the mode, do the following: 1. Turn the ignition key to RUN. 2. Close all of the doors. 3. Apply the brakes. 4. Press and hold the power door lock switch in the lock position. 5. Move the shift lever out of and back into PARK (P) while holding the door lock switch in the LOCK position. 6. Release the door lock switch to set the desired mode. After initially moving the shift lever out of and back into PARK (P), each additional shift cycle will advance the programming from the current mode to the next operating mode. If cycled beyond Mode 4, the vehicle will enter operating Mode 1. Disconnecting the vehicle's battery for up to a year will not affect the programmed mode. Lockout Protection This feature helps to prevent a driver from locking the keys inside of the vehicle by disabling the power door locks when the following occurs: • A door is opened. • The key is left in the ignition. • A power door lock is pressed. The lockout protection feature can be overridden by holding the power door lock switch in the lock position for more than three seconds while the key is in the ignition and any door is open. This feature cannot guarantee that you will never be locked out of the vehicle. If the manual door lock is used or if the key is left in the vehicle, but not in the ignition, you could still be locked out of the vehicle. Always remember to take the keys with you. Leaving Your Vehicle Before leaving the vehicle, take the keys, open the door, and set the locks from inside. Then get out and close the door. See "Delayed Locking" in this section for more information. 2-12
