Which 2018 Focus do you have?

The fuse layout differs between versions of the 2018 Ford Focus. Until you choose, the chart for every version is shown.

Not sure which Focus you have?
  • Ford UK lists the 2018 Focus under more than one model name: Focus (2015), Focus RS (2015), Focus Electric (2015), Focus (2018) and Focus Vignale (2018). Their fuse layouts differ.
  • Ford UK’s Owner Manuals page can find your car’s handbook from its VIN. The page it opens is titled with Ford’s model name, for example “Focus (2015)”.
  • Your printed owner’s handbook, or a franchised dealer with your VIN, can also confirm it.

If you can’t confirm it, keep both results in mind and check the fuse box legend before removing anything.

Option A Focus (2015) or Focus RS (2015)

Tools that may help

  • Fuse assortment kit

    Spare blade fuses in common ratings, so you can swap a blown one at the roadside.

  • Fuse puller

    Grips small fuses without damaging them. Many fuse boxes have one clipped inside the lid.

  • Digital multimeter

    Confirms whether a fuse or socket actually has power, instead of guessing.
