Press and hold N while turning on the ignition. Wait 6 seconds before releasing N. The neutral light will then flash to indicate neutral. Shift into forward gear, press N for three seconds to confirm. Tachometer shows 2.1 Full throttle forward + N to confirm. In gear bank over and confirm with N for three seconds.
