What is the low gas warning on the Subaru Ascent?

The low gas warning on the Subaru Ascent is a fuel-level alert that tells you to refuel soon. It shows a yellow fuel-pump icon on the instrument cluster and may display a “Low Fuel” message on the center display, guiding you to avoid running out of fuel.

What the warning looks and means

Details below explain when it appears and what you should expect to see on your dashboard.

• Icon: A yellow/or amber fuel-pump symbol appears on the instrument cluster.


• Message: On models with a center multi-information display (MID), the words “Low Fuel” (or a similar alert) may accompany the icon.


• Trigger threshold: The warning typically activates when the tank has only a small amount left, commonly around 2–3 gallons remaining, though the exact threshold can vary by model year, engine, and driving conditions.


• Range visibility: The on-board computer usually shows an estimated “Range to E” or similar figure to help you plan the refuel.


• Nature of the alert: This is a routine caution indicating low fuel, not a fault or malfunction in the vehicle.

In short, the warning is a standard reminder to refuel before you run completely dry, with helpful range information to guide your next stop.

What to do when the warning appears

To handle a low-fuel situation safely and efficiently, follow these steps:

• Safely steer to a gas station as soon as possible when the warning comes on.


• Refuel the tank, aiming for at least a half tank or full if convenient to reset the indicator more reliably.


• Check the updated range to empty after refueling to confirm you have enough fuel for your planned route.


• If the warning persists after refueling or the range estimate seems inconsistent, have the fuel sender or gauge inspected by a Subaru service technician.

After refueling, the warning should clear automatically once the fuel level rises above the alert threshold. If it does not clear, consult a dealer for a diagnostic check.

Model-year and feature variations

Subaru Ascent models from different years may present the low-fuel alert slightly differently, but the core idea remains the same: it’s a fuel-level warning, not a mechanical issue. The iconography (fuel pump icon) and the accompanying range readouts may vary with trim level and infotainment configuration.

Key takeaway: regardless of year or trim, the low gas warning signals that the tank is running low on fuel and prompts a refuel to avoid being stranded.

Summary

The low gas warning on the Subaru Ascent is a routine fuel-level alert that appears as a yellow fuel-pump icon on the instrument cluster, sometimes alongside a “Low Fuel” message and a range-to-empty readout. It indicates you should refuel soon and is not indicative of a mechanical problem. Plan a stop at the nearest gas station, refill, and the alert should clear once the fuel level is restored above the warning threshold.

How many miles do I have when my gas light comes on my Subaru?

Having owned Subaru's since 1986 and two new Outbacks and now two new crosstreks since 2007 I've found that the light comes on around when it's suggested there is 50 miles left to drive.

How many miles after low fuel warning?

You can typically drive 30 to 50 miles after your low fuel light comes on, but this number varies by vehicle, driving conditions, and how you drive. To get a more accurate estimate for your specific car, check the owner's manual, and it's best to refuel as soon as you see the light to avoid damage to your car and the risk of running out of gas. 
Factors that affect your remaining mileage

• Vehicle make and model: Different vehicles have different tank sizes and fuel economy, so the reserve amount will change. 
• Driving conditions: Heavy traffic, city driving, and hilly terrain will use more fuel than steady highway driving. 
• Your driving habits: Aggressive acceleration and braking use more fuel than a smooth, steady pace. 
• Vehicle maintenance: A poorly maintained vehicle may have lower fuel efficiency. 

How to estimate your car's specific range

• Consult your owner's manual: It's the most accurate source for how many gallons your car has in reserve when the light comes on. 
• Track your mileage: When you fill up, note your odometer reading. The next time the light comes on, see how far you can drive and then fill up again. You can then calculate the difference. 

Why you should refuel promptly

• Avoid fuel pump damage: When the fuel level is very low, the fuel pump can start to suck in air. This can cause it to overheat and shorten its lifespan, and can potentially damage other components in your fuel system.
• Prevent being stranded: Running out of fuel can be dangerous, especially on a busy road or highway.
• Don't push it: Even if you know your car has a long reserve, don't make a habit of driving on empty. 

What is the most serious Subaru warning light?

What is the most serious warning light? Of all Subaru dashboard symbols and meanings, the Oil Pressure Warning Light, Brake System Warning Light, and Battery Warning Light are possible causes for concern. Still, the Check Engine Warning Light is one of the most urgent symbols.

What is the range of the ascent gas tank?

501 miles
The Ascent has more than 501 miles of driving range on a full tank. Driving on any highway could offer you some more driving miles because you'll make less stops.
