How do you open fuel tank on Daewoo lanos?

To open the fuel tank on a Daewoo Lanos, first ensure the vehicle is turned off. Locate the fuel door release lever, usually found on the driver's side, near the floor or on the dashboard. Pull the lever to release the fuel door, then simply press on the door to open it. If the lever is not functioning, you may need to access the fuel door manually from the outside using a flat tool to gently pry it open.
