that annoying ARROW on my 87 5spd only rears its head when I disconnect the battery for some work that requires a disconnected battery.

Upon reconnect I get that "Volvo Notice" to shift-up as soon as I pull out to the driveway.

I have read, but cannot cite the page/link.--- and have done as advised, it works.

to wit: after power(battery) disconnect...reset the Up-Sf(h)it prompter by driving in 1st--- 20MPH or more....the light will come on--- THEN Shift into the next gear***** at the 'limit speed that you choose'---the light will come on in the next gear when it reaches that 'limit'---which I understood to mean REVS.

The AI(yeh early AI) will have learned where you want the Reminder Arrow to go on.

So if you Don't want to see it prompting you, wind it out in 1st before you shift---Italian Tune IT(setting the REV Trigger)... and the ARROW will be gone until you undo that Positive terminal cnnxtion.

Hope that helps in your Probing--- it's in 'programmable'

PS --- fact checkers please
