Unlock the car, use the interior fuel-door release to pop the door on the driver’s side rear quarter, then access the filler neck. If your Civic uses capless fueling, there’s no cap to remove.
Where the fuel door is and how to access it
The fuel door on most 2017 Civics sits on the driver’s side, toward the rear of the vehicle. It is linked to an interior release, and on many trims you’ll find a lever labeled “Fuel” inside the cabin. If your model doesn’t have a lever, the door may release when you press on its exterior edge once the car is unlocked.
Opening the fuel door from inside
To begin the process, follow these steps:
- Unlock the car with the key fob or door handles so all doors are unlocked.
- Locate the interior fuel-door release lever on the driver’s side, typically near the floor or lower dash, labeled “Fuel.”
- Pull the lever (or press the interior release) to unlatch the fuel door. The door should pop outward slightly.
- Go to the outside of the vehicle and gently press on the edge of the fuel door to open it fully, or pull on it if it requires a manual release.
Note: If the car is locked or the doors aren’t unlocked, the fuel door may not release. Ensure the vehicle is unlocked before attempting the release.
Filling the tank: capless vs traditional cap
Depending on the trim and market, the 2017 Civic may use a capless fueling system or a traditional gas cap with a tether. Here’s how to proceed in each case.
- Capless fueling: There is no gas cap to remove. With the fuel door open, insert the nozzle into the filler neck and fuel will seal automatically when you remove the nozzle. Close the fuel door when done.
- Traditional gas cap: Twist the gas cap counterclockwise to remove; place the cap on the tether while fueling; after fueling, replace the cap by turning it clockwise until you hear a click, then close the fuel door.
Regardless of configuration, make sure the fill area is securely closed after fueling to prevent fumes and meet emissions requirements.
Troubleshooting and tips
Common issues and quick fixes to consider before seeking service:
- The door won’t release if the car is locked. Always unlock the doors first before attempting the release.
- If the internal release feels stuck, ensure the door is not obstructed and the vehicle is unlocked; try again after a moment.
- If you have a capless system and the nozzle doesn’t fit properly, verify you’re using a standard, in-spec nozzle and that the door is fully open.
If the fuel door or release mechanism remains stubborn despite proper unlocking, contact a Honda dealer or roadside assistance to avoid damaging the latch or the fuel system.
Summary
Opening the gas tank on a 2017 Honda Civic involves unlocking the car, using the interior fuel-door release to pop the door on the driver’s side—then opening the exterior door to access the filler. Fuel is added either through a capless system or a traditional cap, after which you securely close the door and, if applicable, reattach the gas cap. If you encounter trouble, consult the owner’s manual or a dealer for trim-specific guidance.
