It's one of the Car Memory options. It will need to be reset by the Stealership. From other threads, changing any of these ranges from Free (glad to be of help to a good customer) to $100+ (grab your ankles, matey) depending on what kind of a lube job the Stealer wants to give you. If you're still getting service from the stealer, oh the horror, you might want to wait until you're getting work done and see if they'll throw it in?
