Bár ez 406-osra vonatkozik, de szerintem ez most itt lényegtelen: [link]

Aztat írja hogy: "Peugeot 406 coolant warning light - this will appear on start up and go out after a few seconds. If the light stays on or re appears when driving it indicates that the engine cooling system is not working correctly. You should stop immediately and allow time for the engine to cool. When the engine of your Peugeot 406 is cool check the coolant levels and top up accordingly. When you top up check for any leaks under the vehicle, as sometimes in older vehicles it is common for coolant pipes or expansion tanks to crack which will lead to loss of coolant. If this happens you should NOT drive any further until the problem is fixed, any further movement could destroy the engine."

Tehát a hűtésre vonatkozik. Az indítás után pár másodperc múlva ki kell aludnia. Ha nem teszi, akkor nem megfelelő a motor hűtése, valószínűleg kevés benne a hűtőfolyadék.
