Hello Viper Dude,
After a week, I finally got around to learning/exploring the menus, i.e. ODO, Tripo, mileage etc.
I wrongly thought that the function "learn" tire pressure was for me to do as a new owner, setting up the car & menus. Of course then I read the manual and figured out that this function was for a tech, I guess after rotating, or new tires, etc.
One question though, I did press & select at the learn screen, the horn beeped back, at which point I realized this was not a function for me.
Given that the horn beeped back, but then no further action was taken, did I accidentally "unlearn" or "disable" my TPMS, if you know?
