I'm renting a Fiesta, not sure which year. It has these buttons on the dash, what do they do?
I already figured out that another button changes the color of the mood lighting nonsense.

Ummm.. push the buttons and see what happens? The second one appears to change the instrument cluster backlight intensity.– 3DaveApr 11, 2018 at 13:10

@DavidLively I pushed them and nothing obvious happened. Pushing random buttons in a car and seeing what they do is not a great strategy, though.– endolithApr 11, 2018 at 14:21

There are 2 of those function buttons.. They are the audio control buttons 1 to 4. They control various audio mode functions like switching between Radio/CD etc.
I don't know what the first one is. The second one adjusts the instrument panel illumination up or down.

The control and symbol are DOT-mandated here in the US. The adjustment might only operate when the headlights or sidelights are on, or be invisible in the daytime, or the control may be broken or disconnected. Apr 10, 2018 at 17:02

I tried again and it does adjust the instrument panel illumination, it's just not very obvious changes. What DOT mandate covers things like this?– endolithApr 11, 2018 at 14:20

1Look in the FMVSS - the Federal Motor Vehicle Safety Standards. Apr 11, 2018 at 15:13

1No idea; I assumed it was in the FMVSS, but don't see it either. It does appear on many cars. Shrug. Apr 11, 2018 at 18:58
