Every red warning lamp on the Peugeot 3008 III (2024-2025) explained in plain English, with what each one means and what you should do next.
A red warning lamp on your dashboard tells you something needs your attention. Some red lamps report a fault that may need further investigation, while others are reminders, such as an open door or an unfastened seat belt. A few red lamps 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. A lamp may also come with a sound and a message on the screen.
This guide covers the third-generation Peugeot 3008 (2024-2025) and applies to cars built from 2 September 2024. Some lamps only appear on certain versions or with certain equipment, for example Petrol, Hybrid, Rechargeable hybrid or Electric models.
