Typically, the gas light comes on when there’s about 10-15% of your fuel tank left, which for most vehicles translates to approximately 30 to 50 miles of driving range, depending on your car’s fuel efficiency and driving conditions. However, this figure can vary by make and model, so checking your owner’s manual or manufacturer’s specifications will give you the most accurate answer for your vehicle.It’s important not to ignore this warning. Consistently driving with low fuel can damage components like your fuel pump, which relies on gasoline for cooling and lubrication. Although you might be tempted to push your luck and drive a little further when the light comes on, making a habit of refueling when the indicator alerts you is your best bet for maintaining your car’s health and avoiding being stranded.From a design perspective, gauges and alerts—like the gas light—are integral to user-centric interiors.
