2019–2024 Hyundai Elantra Fuse Box Diagram

Instrument panel fuse panel (driver's side), Engine compartment fuse panel: every fuse, its amp rating, and what it protects.

Quick answer

Hyundai prints the fuse layout on the inside of each cover and reproduces those labels in the manual, so this diagram follows the label exactly: the driver-side panel under the dash and the engine bay panel next to the battery. This entry is transcribed from the Elantra Hybrid manual; the gasoline Elantra shares the panel design but omits the hybrid-only fuses marked here.

Generation: 7th generation Elantra Hybrid (CN7, 2021–2024) · Body styles: sedan (hybrid)

Instrument panel fuse panel (driver's side)

Location: Under the dashboard on the driver side, behind the fuse panel cover to the left of the steering column. The fuse label is on the inside of the cover.

Replace a fuse only with the same rating. A blown fuse that blows again is telling you about a short or an overloaded circuit, not about the fuse.

Frequently asked questions

Where are the fuse boxes on the 2021 to 2024 Elantra?
Two places. The driver-side panel is under the dashboard to the left of the steering column, behind a cover whose inside carries the fuse label. The engine bay panel sits next to the battery under a clipped plastic cover, also labeled inside.
Which fuse is the fuel pump on the Elantra?
In the engine compartment panel: the 20 A FUEL PUMP fuse in the cartridge row, with the FUEL PUMP relay in the relay bank on the right. SENSOR3 (10 A) feeds the fuel pump relay coil.
My fuse label looks slightly different from this drawing. Why?
Hyundai revises labels by model year and powertrain, and the manual itself warns that the label in your car is the final word. This page follows the 2024 Elantra Hybrid label; gasoline cars omit the hybrid-only fuses. Match by fuse name, not position, if yours differs.
