WHAT DO THESE THINGS DO?

[DSM2]

Hi. Just bought an Iveco 75e17 2002.

There's a button on the cab floor just near the pedals. What is it?

There's a 3 position switch with various symbols the most notable being what looks like a foot hovering over a pedal. At the bottom is the circle with two lines around, like brAke pads. In between is a circle with a little arrow onthe circle and 1 l e line a brake pad.

What's that?

Many thanks for any info!!
