Regardless of whether the driver and front passenger have fastened their seat belts already, the seat belt warning lamp lights up for 6 seconds after every engine start. It then goes out if the driver and the front passenger have fastened their seat belts.

If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. The warning tone goes out after approximately six seconds or once the driver's seat belt is fastened.

If the driver or front passenger have not fastened their seat belt after 6 seconds and the doors are closed, the seat belt warning lamp lights up.

• until the driver or the front passenger have fastened their seat belts
• if a vehicle speed of 15 mph (25 km/h) is exceeded once, a warning tone with increasing intensity sounds additionally for a maximum of 60 seconds or until the driver or front passenger have fastened their seat belts.

If the driver or front passenger undo their seat belts during the journey, the seat belt warning lamp lights up and the warning tone sounds again.

The warning tone ceases even if the driver or front passenger have still not fastened their seat belt after 60 seconds. The seat belt warning lamp stops flashing but continues to be lit.

Once the vehicle is stationary, the warning tone is reactivated and the seat belt warning lamp starts to flash again if the vehicle speed exceeds 15 mph (25 km/h) once.

The seat belt warning lamp only goes out if:
• both the driver and the front passenger have fastened their seat belts.
or
• the vehicle is stationary and a door is open.
