Red warning lamps on the Peugeot 4008 explained: parking brake, brake fluid, EBFD, battery charge and seat belt, with what each means and what to do.
When a red warning lamp comes on while the engine is running or you are driving, it is telling you about a malfunction that needs action from you. Some lamps also come on with an audible signal or a message on the instrument panel screen to help you identify the problem.
This guide covers the first-generation Peugeot 4008 and is based on handbook edition ed01-16, which applies to vehicles produced from 03/10/2016. Some lamps depend on the version or equipment of your car, so you may not see every one listed here.
