What every orange warning lamp on the Peugeot 407 means, from the fuel and oil level lamps to the particle filter, with clear advice on what to do next.
Orange lamps on your Peugeot 407 point to something you need to deal with, a fault you should have checked, or simply a function that has been switched on or off. This guide explains what each one means and what you should do when you see it.
It covers the first-generation Peugeot 407 (2005-2010) and is based on the handbook edition for vehicles produced from 1 February 2010. Some lamps only appear on certain versions or with certain equipment, and the passenger's airbag lamp depends on the country, so your car may not have every lamp listed here.
