How do you reset low tire pressure message on a 2000 Buick Park Avenue Ultra?
Start the engine. Use the SELECT buttons on the driver information center until GAGE PAGE is displayed. Press SELECT buttons until TIRE PRESSURE LOW message is displayed. Press and hold RESET button until TIRE PRESSURE RESET is displayed. After releasing the button, TIRE PRESSURE NORMAL should be displayed.
The message will reset by itself after 100 drive cycles if no further low pressure occurs.
What has been, can be again. (Bob Wills, 1942)
