Where is the fuel tank cap switch for Buick cars?

[MacAxel]

Buick cars do not have a fuel tank cap switch. Simply press the fuel tank cap gently when the vehicle is unlocked to open it. Inside, there is a knob that can be unscrewed for refueling. Buick fuel tank caps consist of an inner and outer cover. The outer cover is generally opened electronically or by a cable control, with very few models requiring a key. The inner cover can only be seen after opening the outer cover and is made of rubber material. Turning it to the right tightens it, while turning it to the left opens it. Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. Its models include the Verano, Excelle, Envision, Regal, LaCrosse, and VELITE5 (new energy). Taking the Regal as an example: it is one of Buick's strategic models, with a body length, width, and height of 4913mm, 1863mm, and 1462mm respectively, and a wheelbase of 2829mm. The optimized front and rear track design enhances both longitudinal and lateral space.
