Where is the fuel tank cap switch on the Envision?

The Buick Envision's fuel tank does not have a switch; simply shift to P (Park). Below is relevant information about the Buick Envision's fuel tank: 1. Cleaning method: After using the vehicle for a period, perform a thorough cleaning and inspection of the fuel tank. When cleaning the tank, rinse the interior with hot water, then dry it with compressed air to remove gasoline vapors inside. Next, immerse the fuel tank in a 10% sodium hydroxide solution for cleaning, followed by rinsing the interior and exterior with running water. 2. Types of fuel tanks: Fuel tanks can be divided into open-type and closed-type. Open-type tanks have their liquid surface exposed to the atmosphere and are equipped with an air filter on the cap. Open-type tanks are simple in structure, easy to install and maintain, and are commonly used in hydraulic systems. Closed-type tanks are typically used for pressurized tanks, filled with a certain pressure of inert gas, with inflation pressure reaching up to 0.05MPa.
After using my Buick Envision for a long time, I found the fuel tank cap switch particularly easy to locate. Once seated in the driver's seat, there's a small circular pull handle near the floor by the left leg, close to the door, which can be reached effortlessly. A firm pull will pop open the fuel tank cap, but remember to do this after unlocking the car, as it's electronically controlled. Having driven this car for three years, I've followed this routine every time I refuel without any issues. It's common for friends to initially struggle to find it, often assuming there's an external button, but its built-in placement here is actually for anti-theft convenience. When refueling, I recommend parking and turning off the engine first, then checking if the pull handle is obstructed by debris to avoid mid-operation malfunctions. Regular maintenance should include cleaning it to prevent rust or looseness, ensuring a much more worry-free driving experience.
