Peugeot 408 I Indicators: Orange Warnings (2026-present)

Orange warning lamps on your Peugeot 408 tell you that a fault may need further investigation, or show you the status of a system that has been switched off or is working. Some orange lamps light up for a few seconds when you switch the ignition on. They should go out as soon as the engine starts. If one stays on, check what it means below.

This guide covers the Peugeot 408 I (2026-present), based on handbook edition ed02-26 for vehicles produced from 09/02/2026. Some lamps only appear on certain versions (ICE, MHEV, PHEV or BEV) or with certain equipment, so your car may not have all of them.

Quick Reference

Orange warning/indicator lights Service

This is the orange Service lamp on your instrument panel. It warns you about faults that have no warning lamp of their own, and it always comes with a message. How it lights up tells you how serious the fault is.

What to do:

If it comes on briefly with a message, one or more minor faults have been detected:

• Use the message on the instrument panel to find out what the fault is.
• You may be able to sort some faults yourself, such as changing the battery in the remote control.
• For other faults, such as a problem with the tyre under-inflation detection system, seek the assistance of a workshop.

If it stays on with a message, one or more major faults have been detected:

• Use the message on the instrument panel to find out what the fault is.
• Then seek the assistance of a workshop.

If it stays on with the message “Audible Warning System fault: Repair needed”, the audible warning system has failed:

• Bear in mind that Traffic Signs Recognition, Active Safety Brake/Collision Risk Alert and Lane keeping assist may be disturbed or unavailable.

Braking

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

What to do:

• Drive carefully.
• Seek the assistance of a workshop.

Malfunction (with electric parking brake)

This orange lamp stays on with the message “Parking brake fault”. The car cannot be immobilised with the engine running. If applying and releasing the brake by hand no longer works, the electric parking brake control itself is faulty.

What to do:

• Use the automatic functions at all times. They switch back on by themselves if the control develops a fault.
• Seek the assistance of a workshop.

Automatic functions deactivated (electric parking brake)

This orange lamp stays on when the parking brake's automatic functions are switched off. That means it no longer applies itself when you switch off the engine, or releases itself when you accelerate.

What to do:

• If automatic application or release is no longer possible, start the engine.

Anti-lock braking system (ABS)

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

This is the orange stability control lamp. It can stay on because the system is switched off or because it has a fault, and it flashes while the system is working.

What to do:

If it stays on because the system is deactivated:

• Traction Control switches back on by itself when you start the car, and above about 31 mph (50 km/h).
• Below 31 mph (50 km/h), you can switch it back on manually.

If it flashes:
