What the green and blue indicator lights on your Peugeot 406 Break (2002) mean, from ESP to diesel pre-heating, and what to do when you see them.
Green and blue lamps on your dashboard are generally there to tell you that a system is working or switched on, rather than to warn you of a problem. Some of them can still point to a fault in certain cases, so it is worth knowing how each one behaves.
This guide covers the Peugeot 406 Break, based on handbook edition ed02-02, which applies to cars produced from 01/07/2002. The handbook does not show the colour of each lamp, so check against your own instrument panel. Some lamps depend on the version or equipment fitted to your car.

Red warning lights are the ones that ask you to stop. On your Peugeot 406 Break they point to a problem with the engine oil, the coolant or the brakes, and the handbook tells you to stop immediately when they come...
Orange warning lights on your dashboard are there to flag a fault, a system that needs attention or something you need to do. They are not usually as urgent as a red light, but you should not ignore them.
A red warning light is the most serious message your dashboard can give you. It usually means you need to stop as soon as it is safe to do so, or at least deal with the problem straight away.
