Where is the fuel tank switch located in a Buick?

The fuel tank switch in a Buick is located inside the fuel tank cover. When the vehicle is unlocked, simply press the fuel tank cover to open it, then twist the internal knob to access the tank. Buick offers various models, and not all fuel tank covers open in the same way. Buick fuel tank covers consist of an inner and outer cover. The outer cover is generally electronically controlled or operated via a cable, with very few requiring a key to open. Taking the Buick LaCrosse as an example: its body dimensions are 5026 mm in length, 1866 mm in width, and 1459 mm in height, with a wheelbase of 2905 mm. The Buick LaCrosse features front-wheel drive, a front suspension type of MacPherson strut independent suspension, a rear suspension type of multi-link independent suspension, and a unibody structure.
When I first bought my Buick, I was curious about where the fuel tank release was. Turns out, it's on the floor near my left foot while driving—just pull the small lever to open the fuel filler cap. I drive a Buick LaCrosse, and the switch is discreet yet convenient to prevent accidental opening. Remember to turn off the engine and remove the key before refueling—safety first. If you're a new driver and can't find it, feel around the lower left side of the seat or check the car’s manual. Don’t waste too much time figuring it out to avoid delaying refueling. If it won’t open, it might be mechanically stuck—try gently pushing it. Once you locate it, refueling becomes much easier.
