Peugeot 406 Coupe (2003-2004) green and blue indicator lights explained: the ASR/ESP stability light and the diesel pre-heating light, plus what to do.
Green and blue lamps on your instrument panel are usually there to tell you something rather than warn you about a fault: they show that a system is working, switched on or switched off. Some of them still ask you to do something, such as waiting before you start the engine.
This guide covers the Peugeot 406 Coupe, based on handbook edition 01-04, which applies to cars produced from 1 January 2004. The handbook text does not print the colour of each lamp, so check the light on your own panel. Some lamps depend on the version, engine or equipment of your car, so you may not see all of them.

| Warning | Urgency | In short |
|---|---|---|
| ASR/ESP Stability indicator light | Information / status | Grip control working or switched off |
| Pre-heating indicator light (Diesel engine) | Action needed from you | Wait before starting the diesel engine |
This is the ASR/ESP stability symbol on your instrument panel. It comes on for a few seconds each time you switch the ignition on. With the engine running and the car moving, it flashes when the system is working, and it stays lit continuously when you have switched the system off.
What to do:
If it flashes while you are driving:
If it stays lit after you have switched the system off:

This is the pre-heating symbol, fitted to diesel models. If the engine is already warm enough, the light will not come on and you can start the engine straight away.
What to do:

If a lamp comes on and you are not sure what it means, stay calm, stop somewhere safe when you can and check your Peugeot 406 Coupe handbook. If the light points to a fault, contact a PEUGEOT dealer.
Green and blue lamps are mostly there to keep you informed, so getting to know them makes it easier to spot when something has changed. Keep an eye on your instrument panel each time you switch the ignition on, and you will soon know what is normal for your car.
