Where is the diagnostic plug on a s max?

In the Ford S-Max, the diagnostic plug, also known as the OBD-II port, is typically located beneath the dashboard, near the driver's side. You can usually find it above the brake pedal or to the left of the steering column. It may be covered by a plastic panel that can be easily removed. If you're having trouble locating it, a flashlight can help illuminate the area for better visibility.
