Hi, welcome to Just Answer. My name is***** red battery warning message is for the starter battery under the hood. After replacing the battery the fault codes stored in the battery control module must be erased using the Mercedes Star Diagnosis tester. You cannot reset the red warning message yourself. The battery and charging system voltage should also be tested to be sure that everything is working properly.
Let me know if you have any questions.
