Gently, very gently, lower the glove box. There is a nylon cord that will support the glove box in a lowered position. If that cord isn't present, lower the glove box onto your knee(s).

By the mount for the nylon cord is the Trunk Main Switch. In the OFF position, this disables opening the trunk from the trunk lid switch by the license plate, and the remote transmitter (key fob) button.

With the entire glove box exposed, now is a convenient time to clean it out with a soft brush or damp microfiber cloth. A sheet torn off a pet hair roller does a good job of picking up stray dust and fibers.

If the glove box courtesy light is burnt out, you can find the bulb holder above the glove box opening to the right of the center. That's another guide....
