Test mode?

[Jaw_F430]

When I picked up my car I was trying to alter the clock. Started playing with the two buttons on the instrument cluster. I pushed and held the left one and the it said "test" where the mileage is normally displayed. What is this function?

Had a read through the manual but can't see anything relating to it?

I had to turn the ignition off the get it go back to normal

Any ideas?

Yeah there's a whole series of diagnostic 'tools' in there. It's not documented in any end-user handbooks, and is very fiddly to use. You can reset the dash service indicators in there for instance. It's so user-unfriendly I'd recommend avoiding if I'm honest.
