hi. i looked thru the manual and a few pages of threads here but couldn't find anything on it. when i turn on that, there is a strip of lights on the dash pad, just before the windshield. it looks like it would be a shift light/light tachometer that lights up and shows on the screen. it lights up when i turn on the car, likes its going thru its test mode like all the other lights/signals/indicators on the dash. then goes off. ive seen this on other cars, its usually a shift light display. but after the initial test where it lights up, i have yet to see it light up but its a new truck and i haven't really jammed it all the way to the red/rev limit. can you set that somewhere? or is that something else entirely. ?
