Engine compartment fuse box (front PDC)
Look for the 2019 300's front fuse box on the passenger side of the engine bay, at the front corner next to the remote battery posts (the battery is under the trunk floor). The latched lid comes off by hand and carries the cavity map on its inside face.
New for 2019: mini 36 also protects the steering-column lock module on cars that have one, next to the anti-lock brake module. The rest follows 2018 — cartridges 2–6 and 18–21 for the high-current loads, 15/16 for HID headlamps and 52 for adaptive cruise.

Trunk fuse box (rear PDC)
Under the trunk floor of the 2019 300, right of the battery, sits the rear power distribution center. Lift the spare-tire cover, release the lid latches and the fuses are exposed, cartridges down one side and mini fuses in rows beside the relays.
The 2019 table follows 2018; the fuel-filler-door fuse (23) is now marked where fitted. The 300's own fuel pump stays on cartridge 21 at 30 A and the transmission module on 26.
