Can I keep driving with the Seat Belt Reminder Light on?
For a Mercedes-Benz Sprinter, a steady amber Seat Belt Reminder Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Seat Belt Reminder Light on a Mercedes-Benz Sprinter?
