Insert key and ensure ignition is off.
Turn key to position 1. With odometer display selected press and hold Answer Call and then OK both on steering wheel. Ignore the beeps you hear - they are from my radar detector.
Vehicle data has build info
Like the engine type, VIN, etc.
This is dyno mode.
When enabled it removes all the safety features. Obviously don't drive it in this mode. It will remain in this mode until you turn it off and turn the ignition off.
The last menu is for servicing reminders etc.
