What feature helps drivers identify the location of the gas cap?

Answer: A — An arrow next to the fuel indicator light

The feature that assists drivers in identifying the location of the gas cap is the arrow next to the fuel indicator light on the dashboard. This arrow points in the direction of the fuel door, indicating whether it is on the left or right side of the vehicle. This is particularly helpful, especially in situations where the driver might not be familiar with the car or when switching between vehicles. Having this visual cue ensures that drivers can easily locate the gas cap without having to guess or check the owner's manual, making the refueling process more efficient and straightforward.
