Mercedes-Benz GLC : Seat belts / Seat belt warning function for the driver and front passenger

The seat belt warning lamp in the instrument display is a reminder that all vehicle occupants must wear their seat belts correctly.

The seat belt warning lamp lights up for six seconds every time the vehicle is started.

In addition, a warning tone may sound.

When the driver's and front passenger's doors are closed and the driver and front passenger have fastened their seat belts, the seat belt warning goes out.

In the following cases, the seat belt warning lights up during a journey if:

• The vehicle speed exceeds 15 mph (25 km/h) and the driver's or front passenger seat belt is not fastened.
• The driver or front passenger unfastens their seat belt while the vehicle is in motion.
