Peugeot 407 I Indicators: Red Warnings (2004-2005)

A red warning lamp on your dashboard usually needs your attention, and some of them mean you should stop straight away. This guide covers the first-generation Peugeot 407, based on handbook edition ed01-05, which applies to cars produced from 01/02/2005.

Not every lamp will be fitted to your car, as some depend on the version, equipment or country. A few lamps appear more than once in the handbook with slightly different wording or symbols, and each entry is covered here.
