Checking and Replacing Fuses
In order to prevent damage to the electrical system due to short circuits and overloads, fuses protect the individual circuits.
- Switch off the load with the defective fuse.
- Pull off plastic cover at the finger hole (arrow).
- 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.
- 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.
