Hi,
You must have the OBC (Onboard Computer) Option - 2 stalks on the Steering Column. Move the stalk on the lower left either up or down to scroll through the functions.
If you don't have OBC, only 1 function can be displayed and this is often the Temp - turned on as a courtesy by the Dealer. If this is what you have, and the Display changed by itself, you have some kind of glitch and a Dealer will need to reset it.
If you lack the OBC Option, it is fairly easy to retrofit the necessary wiring and switch. Hope this helps...
Happy Motoring!... Jim'99
