Engine compartment fuse box (front PDC)
In the 2020 300 the engine-compartment box has not moved: passenger side, front of the bay, beside the positive and ground posts used for jump-starting because the battery is in the trunk. Unclip and lift the cover; the label inside it numbers each cartridge and mini fuse.
The 2020 book renames 34 and 35 to the auto-shutdown (ASD) relay feeds, trims 37 to the engine controller and rewrites 39 as A/C clutch, electric power steering and vacuum pump. Positions 7, 8, 22–24 and 29 are still reserved for police and other models.

Trunk fuse box (rear PDC)
The 2020 300's rear fuse box is below the trunk floor, fastened beside the battery on the right-hand side of the spare-wheel well. Raise the access panel and unclip the cover; the label inside the cover numbers each cavity.
In 2020 cavity 33 adds remote start, 12 becomes the instrument-panel 12 V outlet plus rear USB, 38 the media hub and console outlet, and 52 now covers heated and cooled cupholders. The lane-departure camera stays on 45.
