That's the fog light. To turn on, with the car on, just twist the light switch over one or two clicks, to first turn on the parking or regular low beam lights, and then pull the switch out (towards you). One pull towards you will turn on the fog light. Two pulls will also turn on the rear fog lamp (drivers side). There is no passenger side rear fog light on purpose, as you don't want people behind you thinking you are riding your brakes.
