I have a yellow rectangle at the end of my speedometer see attached. In other (possibly unrelated issues) is the fuel gauge frequently drops to zero and comes back again.

I’ve ordered a new fuel tank pump and sender assemble.

Anyone have any idea what the yellow rectangle is for? Note the cruise control functions normally and graphically.

I think you will find thats the speed limiter which has been set to max

what he said ^^

limit speed set to on and on its max setting. Just turn it off and the orange indicator will go away.  There is nothing that can't be fixed with a hammer😜😜

It doesn’t actually limit the speed, it just pings an alert up on the dash regarding speed warning.

Useful sometimes though.
