How many miles do I have to drive the car to reset the drive cycle

Stella, There is no preset number of miles that must be driven to run the drive cycle. To complete the drive cycle, the vehicle must be driven long enough to put the vehicle in enough different conditions for the computer to run enough self tests to determine that it is "ready". Generally speaking, if the vehicle is driven on a combination of surface streets & freeways it will take about a week to go through all of the tests. Any Repair pal shop can get you a copy of the drive cycle, but it is somewhat confusing.
