The little arrow next to your car’s fuel gauge is a simple but useful feature:
- It points to the side of the car where the fuel filler door is located.
- If the arrow points left (◀), your gas cap is on the left side.
- If it points right (▶), the gas cap is on the right side.
This is especially helpful when:
- You’re driving a rental car.
- You’ve borrowed someone else’s vehicle.
- You own multiple cars and can’t remember which side the fuel door is on.
A few extra details:
- Most cars built since the late 1990s and early 2000s include this arrow, but not every vehicle has one.
- On some older cars without the arrow, the position of the fuel pump icon itself may indicate the fuel door side, although this is not a universal standard.
- The arrow is part of the instrument cluster and has no connection to fuel level, fuel economy, or warning lights—it serves only as a quick reminder of the fuel door location.
It’s one of those small design features that can save time and prevent awkward moments at the gas station.
