you can't. there is only the option of having it either on or off.
I have a 2011 Sonata SE and the sensor for the auto headlights is on the FRONT (windshield side) of the rear view mirror.
One can program the mirror garage door opener on a Hyundai by pushing the home link button first and holding it. It will then flash slowly with a red light on the mirror. One second later, point the garage opener to the mirror and push the open button.
This is a common problem on these auto dimming mirrors. The fluid that is in the mirror leaks and causes a blur. They are expensive to replace and often times people replace them with a regular, non dimming mirror.
Remove the factory speaker cover on the inside of the door and remove the 3 screws from the mirror. The speaker cover is held in with 2 clips, one at the top and one at the bottom. They are friction fit clips.
pull up to face your garage door hold the mirror button in and the garage door opener in until the red light on the mirror turns green. viola

The auto dimming rearview mirror contains chemicals that have either leaked out or deteriorated over time. You will have to replace the mirror.
not acid, has fluid for auto dimming
the mirror turns a greenish yellow because of the chemical used to make it auto dimming. The mirror glass needs to be replaced. A GM part item.
I had the same problem and saw there was no answer. We figured out it's on the same fuse as the cigarette lighter. In the fuse box located under the hood, up of the battery. You unscrew the wing night and the box comes off.
You need 3 connections, (+) key on, (-) ground, and (+) reverse. The auto dimming mirror looks for (+)on the sense line so it can automatically lighten up when the vehicle is placed in reverse. If running a wire from your backup light circuit isn't appealing, then you can just leave it out, but the mirror needs a switched 12v supply and a ground. Some mirrors also have a compass and a thermometer.
remove the fuse fuse is called the anti dazzel feature i belive
