The button to change the display is on the end of the turn signal stalk. You may have to press it several times, as there are a lot more functions than just the two you mentioned.

The lock button is on the center console next to the hazard flasher button, just behind the shifter, next to the parking brake handle.How to change the display from mpg to ';miles i can drive'; in the dash of BMW? ?
Do you have the navigation? If you dont, it should be on the steering wheel. The lock button is underneath the gear shifter next to the hazard button.
