To replace the battery in a Mercedes M-Class, push the front passenger seat all the way forward to access the protective panel underneath. This panel can be detached from its housing to reveal the device.

The battery must then be released from its seat by loosening the screws that hold it in place and disconnecting the power cables. Once the old battery is removed, insert the new one into its seat, cover everything with the panel, and ensure that everything functions correctly.
