What the Low Fuel Warning Light Means on a Peugeot 408
On the Peugeot 408, this amber pump symbol tells you it is time to refuel soon. Repeatedly running the tank to empty can shorten fuel pump life, since fuel helps keep the pump cool.
How Urgent Is the Low Fuel Warning Light?
Urgency level for this indicator on the Peugeot 408: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Low Fuel Warning Light appeared, how the Peugeot 408 is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
