Peugeot 308 III Indicators: Orange Warnings (2025-present)

Orange warning lights tell you that a system has a fault or that its status has changed, for example a function has been switched off. If an orange light comes on and stays on, there may be a fault that needs further investigation. Some orange lights come on for a few seconds when you switch on the ignition and should go out once the engine has started.

This guide covers the Peugeot 308 III (2025-present), based on handbook edition ed09-25 for vehicles produced from 12/09/2025. Some lights only appear on certain versions or with certain equipment, such as petrol, BlueHDi Diesel, MHEV, PHEV or BEV models.

Quick Reference

Orange warning/indicator lights Service

This is the orange Service warning light, which reports faults that have no warning light of their own. If it comes on briefly with a message, one or more minor faults have been found. If it stays on with a message, one or more major faults have been found, and if it stays on with the message "Audible Warning System fault: Repair needed", the audible warning system has failed, so road signs recognition, Active Safety Brake/Collision Risk Alert and lane keeping assist may be disturbed or unavailable.

What to do:

If it comes on briefly with a message:

• Read the message on the instrument panel to find the cause. You can deal with some faults yourself, such as changing the battery in the remote control, but for others, such as a fault with the tyre under-inflation detection system, get help from a workshop.

If it stays on with a message:

• Read the message on the instrument panel to find the cause, then get help from a workshop.

If it stays on with the audible warning system message:

• Bear in mind that road signs recognition, Active Safety Brake/Collision Risk Alert and lane keeping assist may not work as normal.

Braking

This is the orange braking warning light. When it stays on, a minor fault has been detected in the braking system.

What to do:

• Drive carefully.
• Get help from a workshop.

Malfunction (with electric parking brake)

This is the orange electric parking brake malfunction light. It stays on with the message "Parking brake fault" and means the car cannot be held stationary by the parking brake while the engine is running. If applying and releasing the brake by hand does not work either, the electric parking brake control is faulty.

What to do:

• Take extra care when you stop and park, as the parking brake may not hold the car.

Automatic functions deactivated (electric parking brake)

This is the orange light for the electric parking brake's automatic functions. When it stays on, automatic application when you switch off the engine and automatic release when you accelerate are both deactivated.

What to do:

• Apply the parking brake yourself when you switch off the engine.
• Release the parking brake yourself before you drive off.

Anti-lock braking system (ABS)

This is the orange ABS warning light. When it stays on, the anti-lock braking system has a fault, but the car still has conventional braking.

What to do:

This is the orange stability control light. When it flashes, the ESC/ASR system is working because the car is losing grip or its line. When it stays on, either the system has been deactivated or the ESC/ASR system has a fault.

What to do:

If it stays on because the system is deactivated:

• The system switches back on automatically when you start the car and at speeds above about 31 mph (50 km/h). Below 31 mph (50 km/h), you can switch it back on manually.

What to do:

If it stays on with the range message:

• Top up the AdBlue® promptly, or get help from a workshop.

If it flashes with the range message:

• You must top up the AdBlue® to stop the engine being prevented from starting, or get help from a workshop.

If You're Not Sure

If you are not sure what a light means, read the message on the instrument panel and check the handbook section for that system. A red or orange light that stays on may point to a fault that needs further investigation, so if in doubt, get help from a workshop.

Orange lights are usually a prompt to check something rather than an emergency, but they are worth taking seriously. Keep this guide handy so you can quickly see what your Peugeot 308 is telling you.
