Checking and Replacing Fuses

In order to prevent damage to the electrical system due to short circuits and overloads, fuses protect the individual circuits.

  1. Switch off the load with the defective fuse.
  2. Pull off plastic cover at the finger hole (arrow).
  3. Remove the corresponding fuse from its slot using the plastic gripper in order to check it. A blown fuse can be identified by the melted metal strip inside it.
  4. Replace only with fuses of the same rating. We recommend that you use genuine Porsche fuses for replacement.

Notice

  • Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. Never replace a broken fuse with anything other than a new fuse (such as wire, foil, etc). This can cause damage to the electrical system and fire.
  • If a fuse blows repeatedly, please contact a qualified specialist workshop.
