What the Low Fuel Warning Light Means on a Buick Regal
On the Buick Regal, 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 Buick Regal, 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 Buick Regal 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.

As a rule, if the light is red or flashing, or the Buick Regal is running poorly, stop somewhere safe and arrange help rather than pushing on.

Try not to habitually run a Buick Regal down to the light — the in-tank fuel pump relies on fuel to stay cool, and constant near-empty running wears it out.
Frequently Asked Questions
Why is the Low Fuel Warning Light on in my Buick Regal?
On a Buick Regal, the Low Fuel Warning Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Low Fuel Warning Light on?
For a Buick Regal, a steady amber Low Fuel Warning Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Low Fuel Warning Light on a Buick Regal?
There is no single price for the Low Fuel Warning Light on a Buick Regal; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Low Fuel Warning Light reset itself on a Buick Regal?
If the trigger was temporary, a Buick Regal may turn the Low Fuel Warning Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
