If the indicator lamp and the ABS indicator lamp 
light up and the message appears, there is a malfunction in the anti-lock brake system or electronic differential lock. This will also cause an ESC malfunction. The vehicle can still be braked in the normal way (however the ABS control function will be out of action).

WARNING!
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 vehicle to skid sideways. Drive carefully to the nearest qualified workshop and have the fault rectified.
