    LED-looking square near headlights controls, what is it?

    So there is a little dot that looks like an LED near the headlight controls to the left of the steering wheel. I'm not sure what it is and I thought it might be a photovoltaic sensor. What exactly is this and what is it for?

    It is ambient light sensor that is used to auto adjust your odometer read out brightness. Next time you have your headlights on during the day, close the sensor with your finger for ~ 10 second and look at your odometer field - it should slowly dim.
