The Gas Icon Arrow Serves a Purpose
Everyone has been unsure which side the gas tank is on your car at least once, especially if you just got the car. Most people must get out of the car to confirm which side they should go to when they pull up to the gas station.

But this can be time-wasting. However, every car has a feature that indicates which side the tank is on. So, the next time you need gas, just look behind the steering wheel and find the arrow beside the gas icon. Whichever way it points is where your gas tank is.
