When in doubt, perouse the manual!Very timely...I am about to embark on my first ///M5 road trip. Can i simply check the pressure and add air if necessary without messing with the tire pressure warning system..wich I am not so familiar with so far. Thanks.
Actually, step zero is to buckle your seat belt first. If you don't, all you will see in the display is "Fasten Seatbelt". After step 2, do not turn ignition off but go directly to start, and then keep engine running and drive car 5-10 min.Activate the system
1 Turn the ignition key to position 2 (do not start the engine).
2 Press and hold the button (arrow) until the message "SET TIRE PRESSURE" is displayed for a few seconds in the Check Control.
3 After you have driven a few minutes, RDW transfers the current tire inflation pressures as the nominal values to be monitored.
