What the Seat Belt Reminder Light Means on a Mercedes-Benz GLS
The seat-belt reminder on a Mercedes-Benz GLS 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?
How worried should you be? For the Seat Belt Reminder Light on a Mercedes-Benz GLS, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing.

Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.
