| Fuses | Fuse work and accessories: dealer or qualified workshop only |
The handbook is clear on this point: you should not change a fuse yourself on the Peugeot 408.
If you think a fuse has blown, leave it to a PEUGEOT dealer or a qualified workshop.
No. The handbook says all fuse work must be carried out only by a PEUGEOT dealer or a qualified workshop, because a fuse replaced by anyone else could cause a serious malfunction of the vehicle.
The electrical system is designed for standard or optional equipment. Before you fit any other electrical equipment or accessories, contact a PEUGEOT dealer or a qualified workshop.
No. PEUGEOT accepts no responsibility for repair costs or malfunctions caused by accessories it has not supplied or recommended, or that were not installed in line with its recommendations.
The handbook says PEUGEOT accepts no responsibility for resulting faults in particular when the combined power consumption of all the additional equipment connected exceeds 10 milliamperes.
Fuses protect your 408's electrical system, so any work on them is a job for a PEUGEOT dealer or a qualified workshop. Check with them before you add any electrical accessories, and you will avoid unexpected faults and repair bills.
