These instructions apply to the Hyundai i40 Mk1 (VF) 2011-2019.
For other models, please choose your vehicle here.
The Hyundai i40 (VF, 2011–2019) has two main fuse boxes: one in the engine bay by the battery, and one on the end of the driver’s-side dashboard. Here is where to find them and how to change a blown fuse safely.
Where the i40 Fuse Boxes Are
- Engine compartment: next to the 12 V battery, under a clip-off lid. This box holds the high-current fuses and main relays.
- Cabin: on the end face of the dashboard on the driver’s side, hidden by a small pull-off panel that is only visible with the door open.
- The lid of each box carries the fuse legend for your own car — always read that, because fuse assignments and amperages vary by engine, trim, market and options.
How to Replace a Blown Fuse
- Switch off the ignition and the circuit that isn’t working.
- Pop the cover and use the lid legend to find the right fuse.
- Pull the fuse with the plastic puller clipped inside the lid. A blown fuse has a broken metal strip.
- Fit a new fuse of exactly the same amp rating (shown on the fuse and the legend).
- If the new fuse blows straight away, there is a fault on that circuit — have it checked rather than fitting another.
Safety
Never fit a higher-rated fuse, and never use wire or foil in place of a fuse — both can cause wiring damage or a fire. Airbag, ABS and other high-current circuits are best left to a specialist.
Frequently Asked Questions
Where is the diagram of the fuses?
On the inside of each fuse-box lid. That legend is specific to your car, so use it rather than a generic chart.
Which fuse is the 12 V socket or cigarette lighter?
Check the lid legend — it’s usually labeled “ACC,” “power outlet” or a lighter symbol, but the slot varies by model year.
Why does the same fuse keep blowing?
A repeat blow means a short or an overloaded circuit, not a weak fuse. Have the circuit diagnosed.
