These instructions apply to the Hyundai i30 Mk3 (PD) 2017-Present.

The Hyundai i30 Mk3 (PD, 2017–present) has two main fuse boxes: one inside the car at the end of the dashboard on the driver’s side, and one in the engine bay. This guide shows where they are and how to change a blown fuse safely — without copying out a slot-by-slot chart, because the exact layout varies by engine, gearbox and trim.
Where the Fuse Boxes Are
- Interior fuse box — behind a pull-off cover on the end face of the dashboard, driver’s side. It’s hidden when the door is shut and exposed when you open the driver’s door.
- Engine-compartment fuse box — a black box on one side of the engine bay, with the main fuses and relays under a clip-off lid.
A plastic fuse puller and some spare fuses are usually clipped inside the engine-bay box lid.
How to Check and Change a Fuse
- Switch everything off and turn off the ignition before touching a fuse.
- Read the legend on the inside of the fuse-box lid (or in the owner’s handbook) to find the fuse for the circuit that isn’t working.
- Pull the suspected fuse straight out with the puller — never use pliers or anything metal.
- Hold it to the light: a broken metal strip inside means it has blown.
- Fit a new fuse of the exact same amperage (printed on top and colour-coded). Using a higher rating can overheat the wiring.
If the New Fuse Blows Again
A fuse that blows immediately points to a fault in that circuit — a chafed wire or a failed component — not a fuse that needs ‘upgrading’. Have the circuit checked rather than fitting a bigger fuse.
Leave fuses and relays for safety-critical systems — airbags, ABS, engine/transmission control, glow plugs — to a workshop; a wrong move there can disable a safety system.
Frequently Asked Questions
Where is the i30 interior fuse box?
Behind a cover on the driver’s-side end of the dashboard, reached with the driver’s door open.
Why won’t I publish a full fuse chart?
Fuse assignments and amperages differ between engines, gearboxes, trims and markets, so a chart from one car can be wrong for another. The correct map for your i30 is printed on the fuse-box lid.
Can I use a higher-rated fuse if it keeps blowing?
No. The rating protects the wiring. A repeatedly blowing fuse is a fault to diagnose, and a stored code can be read on autodtcs.com.
