With the reversing camera the red lines show you the absolute minimum radius when turning on full-lock, the green grid shows your current steering angle. To reverse straight into a space drive until the red line is just inside the bay, apply full lock and reverse in. Check the video demonstration in the in-car handbook on the i-Drive display.
