This lever will be marked with a gas pump icon and can be found underneath your instrument panel. If you sit in the driver’s seat and look to the lower left of your steering wheel, you should see it. Once you locate this lever, pull up on it and then release. This will cause your exterior fuel door to pop open.
After you pop open your fuel door, you’ll be able to nurse the door fully open and access the gas cap. Simply unscrew your car’s gas cap to access the 2013 Versa’s gas tank and fill up. Then, when you’re done, simply screw the gas cap back on until you hear a click and push the fuel door closed until you feel it catch.
