The small arrow next to the fuel pump icon on your dashboard indicates which side of your vehicle the fuel filler door is located.
This is a common feature on most modern vehicles designed to help drivers quickly identify the location of their gas tank. When you are at a gas station, especially in an unfamiliar car like a rental or a newly purchased model, simply look for the fuel pump symbol. A small triangle or arrow pointing left or right will be positioned next to it, directly showing you which side of the car to pull up to the pump on. This saves you from guessing or having to circle the pump unnecessarily.
The presence and exact appearance of this indicator can vary slightly between different car manufacturers and models.
How do I know which side my gas tank is on if the arrow is unclear?
If the arrow on your fuel gauge is unclear or absent, you can often determine your gas tank side by looking at the fuel gauge itself. Many vehicles display the fuel pump icon, and the arrow will be positioned next to it. If it's still not obvious, check your car's owner's manual; it will explicitly state the location of the fuel filler door. Alternatively, a quick visual inspection of the rear sides of your vehicle will reveal the filler door.
