What the Low Fuel Warning Light Means on a Infiniti QX50
On the Infiniti QX50, 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?
How worried should you be? For the Low Fuel Warning Light on a Infiniti QX50, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Infiniti QX50 still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.
