What every red warning light on the Peugeot Partner III van (2018-2021) means, from STOP and oil pressure to brakes, and what you should do next.
A red warning lamp on your dashboard usually means a fault that needs attention, and some of them mean you must stop as soon as it is safe to do so. A few red lamps simply tell you about something you need to deal with, such as an open door or an applied parking brake. Some red lamps also come on for a few seconds when you switch on the ignition. This is normal, and they should go off as soon as the engine starts.
This guide covers the red warning lamps on the Peugeot Partner III van (2018-2021). It is and applies to vehicles built from 1 October 2019. Some lamps depend on the version or equipment of your van, so you may not see every one listed here.
