2001 Buick Century Owner's Manual - Page 83

When your vehicle was shipped from the factory, it was programmed to Mode 3. The mode to which your vehicle was programmed may have been changed since it left the factory. To determine the security feedback unlock mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following: 1. Close all doors and turn the ignition key to RUN. 2. Press and hold the power door lock switch in the unlock position. While holding the door lock switch in the unlock position, press and release the remote keyless entry transmitter UNLOCK button. This will start the customization mode. While in the customization mode, the feature will sound the number of chimes corresponding to the current unlock mode. (If you do not wish to change the current mode, you can either exit the programming mode by following the instructions listed here or program the next feature available on your vehicle.) 3. Each additional press of the remote keyless entry transmitter UNLOCK button will cause your vehicle to advance the unlock mode by one, starting from the current unlock mode. 4. If cycled beyond unlock Mode 4, the vehicle will enter unlock Mode 1. When the door lock switch is released, the vehicle will remain in the most recent unlock mode. The mode you selected is now set. You can either exit the programming mode by following the previous instructions or program the next feature available on your vehicle. Disconnecting the vehicle's battery for up to a year will not change the programmed mode of the lock and unlock security feedback features. Delayed Locking Delayed locking allows the doors to be locked while passengers are exiting the vehicle. This feature also provides a brief time period after all the doors are closed, but before the doors are locked, in which the doors may be reopened. Delayed locking is user programmable for enabling or disabling the feature. Delayed locking is activated when a door lock switch is pressed while the key is not in the vehicle's ignition, and a door is open. The door lock switch may be either the lock switch on the door or on the remote keyless entry transmitter (see "Remote Keyless Entry" earlier in this section for more details). The doors do not lock when the lock switch is pressed, but instead, three chimes are heard. These chimes indicate that the delayed locking feature has been activated. 2-13
