For those who already have the auto dimming mirror and have misplaced the instructions, here is an easy reference to program it. For more detailed instructions or further information please refer to the HomeLink website at www.homelink.com.

Programming For The First Time:

1. For first-time programming, press and hold the two outside buttons (the first and third buttons from the left) until the indicator light begins to flash (after 20 seconds). Release both buttons.
2. Hold the end of your handheld transmitter between 1 and 3 inches away from the HomeLink surface keeping the indicator light in view.
3. Using both hands, simultaneously push the handheld transmitter button and the desired HomeLink button. DO NOT release the buttons until step 4 has been completed.
4. Press and hold the trained HomeLink button and observe the indicator light.
-If the indicator light is solid/continuous, training is complete and your device should activate when the HomeLink button is pressed and released.
-If the indicator light blinks rapidly for 2 seconds and then turns a solid/continuous light, proceed with the following training instructions for a rolling code device. A second person may make the following steps quicker and easier.
5. To program the remaining two buttons, follow steps 2 through 4.

Rolling Code Programming:

Most garage door openers manufactured after 1996 have rolling codes. You can find out if your garage door opener is by taking the following steps:

-Reference the garage door opener owner's manual for verification.
-The handheld transmitter appears to program the HomeLink Universal Transceiver but does not activate the garage door.
-Press and hold the trained HomeLink button. The garage door opener has the rolling code feature if the indicator light flashes rapid and then turns solid after 2 seconds.

To train a garage door with the rolling code feature, follow these instructions (the aid of a second person may make the training quicker and easer):

1. Locate the training button on the garage door opener motor head unit. Exact location and color of the button may vary by garage door opener brand. If there is difficulty locating the training button, reference the garage door opener owner's manual or please visit www.homelink.com.
2. Press the training button on the garage door opener motor head unit (which activates the "training light"). Note: Following step 2, there are 30 seconds in which to initiate step 3.
3. Firmly press and release the programmed HomeLink button. Press and release the HomeLink button a second time to complete the training process. (some garage door openers may require you to do this procedure a third time to complete the training.)

Reprogramming a Single HomeLink Button:

To program a device to HomeLink using a HomeLink button previously trained, follow these steps:

1. Press and hold the desired HomeLink button. DO NOT release until step 4 has been completed.
2. When the indicator light begins to flash slowly (after 20 seconds), position the handheld transmitter 1 to 3 inches away from the HomeLink surface.
3.Press and hold the handheld transmitter button. The HomeLink indicator light will flash first slowly and then rapidly.
4. When the indicator light begins to flash rapidly, release both buttons.

The previous device has now been erased and the new device can be activated by pushing the HomeLink button that has been just programmed. This procedure will not affect any other programmed HomeLink buttons.

Erasing The Previously Programmed Buttons:

Individual buttons cannot be erased. However, to erase all three programmed buttons:

1. Press and hold the two outside buttons (the first and third buttons from the left) until the indicator light begins to flash (after 20 seconds).
2. Release both buttons. All the buttons are now clear. At this point refer to the beggining of this article to re-program the buttons as if it was the first time.
