Video tutorial

This video shows how to check and replace the fuse boxes on the Mercedes R-Class and GL: the cabin fuse boxes are located within the thickness of the dashboard, and the relay box is positioned above the wheel arch inside the boot, on the right side.

A third box is also found on the right side of the vehicle, within the engine compartment, near the engine air intake.

There are also fuses at the front of the engine, not shown in the diagram, as seen in the video. Another box is located in the battery compartment, under the passenger seat, and is particularly important as it protects the vehicle from short circuits in case of impacts.
