  • If the brake warning lamp lights up together with the ABS indicator lamp and the ESC indicator lamp, this can mean that the control function of the ESC/ABS is not working. Input from the functions that stabilise the vehicle is no longer available. This could cause the tail of the vehicle to skid sideways. Drive carefully to the nearest qualified workshop and have the fault rectified.
