What’s the dial button for

so I got under the driver side and I looked and I saw this 2 buttons, fist one I figured it’s for the TPMS reset but the other one, what’s it for? I never bothered to read the manual. I played with it and I see no difference. Can any one of the vets here shed some light and tell me what it’s for.
thanks in advance

 

Instrument panel dimmer switch. It's suggested to never run on full bright or leds in dash can burn out.
I'm wrong in front of many people I respect. A reminder to myself and others about our fallibility as humans.
But, find that instrument panel dimmer and lower the brightness to save yourself the heartbreak of burned out led bulbs!

 

It's for the power output of the flux capacitor.
Woops....that's my other car.

Here ya go, and I think it includes the fob lock-unlock/alarm beeps or chimes. "Buzzer" isn't the best description though, right?

 

It actually is referring to a 'buzzer', not chime. Buzzer is located outside of the vehicle, wheel arch. Yeah. That **** always bothered me.

 

That **** to control the volume of the lock and unlock chime is a great feature. I keep the chime off, less attention that way.
