What the Seat Belt Reminder Light Means on a Ford Focus ST
The seat-belt reminder on a Ford Focus ST lights (often with a chime) when a front occupant is unbelted. If it stays on despite everyone being buckled, a belt buckle switch or an occupancy sensor may be faulty.
How Urgent Is the Seat Belt Reminder Light?

Is It Safe to Drive With the Seat Belt Reminder Light On?
Whether it is safe to keep driving your Ford Focus ST with the Seat Belt Reminder Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Ford Focus ST is running poorly, stop somewhere safe and arrange help rather than pushing on.
