Driver's side fuse panel
On a 2021 i30 the interior fuses live in the dashboard's driver-side end panel, behind a removable cover above the pedals. Forty-five pockets stand in eight columns around a small OFF/ON rocker; the rocker cuts the car's standing current and is the first thing to check if a car left for weeks will not wake up.
The numbers on this diagram are the handbook's, counted top to bottom down each column and then on to the next column to the right; the printed names - MODULE 1 through MODULE 7, SMART KEY 1 and 2, P/WDW, MULTIMEDIA - open every description underneath. 2021 was the PD's last full model year, and the newest handbook edition Hyundai published for it is still the 2019 one, which is what this page follows.

Engine compartment fuse panel
A 2021 i30 carries its engine bay fuses in a moulded box beside the battery on the left-hand side; the cover lifts off upwards and the fuse puller clips into the bottom corner of the housing, next to the four relays drawn along the foot of this diagram.
Fourteen relays surround the fuses: RLY.1 to RLY.8 in the two columns at the top right, the large cooling fan and blower relays RLY.9 and RLY.10 beneath them, and RLY.11 to RLY.14 across the bottom. The fuse numbering is the handbook's F1 to F52, with unassigned numbers left out. The last edition with a published table is the 2019 handbook, so match the label on your own lid before replacing anything on a late car.
