Peugeot 2008 II Indicators: Red Warnings (2025-present)

A red warning light on your Peugeot 2008 means there may be a fault that needs further investigation, or something that needs your attention straight away. Some red lights also come on for a few seconds when you switch on the ignition and should go off as soon as the engine starts. That is normal.

This guide covers the second-generation Peugeot 2008 (2025-present), based on handbook edition ed05-25 for vehicles produced from 02/05/2025. Some lamps depend on the version or equipment of your car, so not every light here will appear on yours.

Maximum coolant temperature (MHEV)

This symbol warns about the coolant temperature. It stays on, with the display blocks lit in red on the matrix instrument panel or on its own on other instrument panels, when the temperature of the cooling system is too high.

Door(s) open

This symbol shows an open door. It stays on with a message identifying which door or the tailgate is concerned. At speeds below 6 mph (10 km/h), it means a door or the tailgate is not properly closed. It can also come on together with an audible signal.

What to do:

If the light is on with a message only:

Engine Coolant Temperature Warning Light

These symbols relate to the engine coolant temperature gauge. With the engine running, zone A means the temperature is correct and zone B means it is too high. In zone B, the coolant temperature warning light and the STOP warning light come on in red, with a message and an audible signal.

If You're Not Sure

If you are not sure what a red light means, stay calm, stop somewhere safe and check the message on the instrument panel. If a red light stays on, there may be a fault that needs further investigation, so have the car checked by a dealer or a qualified workshop.
