The method for erasing the Homelink programmed button memory is incorrectly described in the owner's manual. The incorrect description in the owner's manual is: "Erasing the buttons" Press and hold both of the outer buttons until the LED (A) turns off completely (about 20 seconds) to erase all of the buttons simultaneously". The correct way to erase the Homelink programming is to press and hold the two outer Homelink buttons, releasing only when the Homelink indicator light begins to flash after approximately 10 seconds.
