Listings are copied as text from the manual's fuse tables (AI-assisted; every circuit name was matched against the cited pages 2026-10-18). Fuse layouts can differ by trim and year; check the label on the fuse box cover before replacing a fuse, and always use the same amp rating.

Confirm with your own manual, dipstick or door-jamb label.
