How do you manually open the gas tank on a BMW x5?

To manually open the gas tank on a BMW X5, first ensure the vehicle is in a parked position and turned off. Locate the fuel door release lever, which is typically found on the driver's side near the floor or on the lower dashboard. Pull the lever to release the fuel door, then gently open the gas tank cover. If the lever doesn't work, you might need to access the release mechanism from inside the trunk, depending on the model year.
