Unlock Gear Selector Light

This green shoe is inside the usual symbol for brake-related items—a circle with small arcs at the three and nine o'clock positions that represent an old-time brake drum and shoes—and is found only on vehicles with automatic transmissions. It's telling the driver they need to step on the brakes to unlock the gear selector before moving it from the park position. Once a foot is pressed on the brake pedal, it should go out.
