How to reset the maintenance light on an old Mercedes ML350?

[VanAdalynn]

You need to display the mileage page in the menu, press the middle "R" key three times, hear a beep sound, enter the new menu, scroll to the servicemenu, find serviceaddi, select SERVICE13, and choose 229.5 or 229.5. The following is an introduction to the maintenance light: 1. Introduction: The maintenance light is a reminder function set by the car manufacturer to prompt the owner to perform maintenance at certain mileage or time intervals, in the form of an instrument or screen message or indicator light. Resetting the maintenance light means resetting the reminder information after maintenance is completed, which is essentially an information reset. 2. Function: The function of the maintenance light is to record the mileage of some important components, just like a timer in a sprint race, serving as a reminder for the owner and automotive repair personnel. If the owner replaces the relevant components but does not reset the light, it will not affect the vehicle's performance, but it will cause trouble for the next replacement of car components, as the exact time of the new component's use cannot be accurately known.
