When the driver's side door is unlocked, press the end of the fuel tank door near the rear of the vehicle, and the fuel tank door will pop open gently. Rotate the fuel tank cap counterclockwise to open it, and secure the cap's tether to the fuel tank door to avoid dirtying the car body. After refueling, reinstall the fuel tank cap by rotating it clockwise until a "click" sound is heard, indicating that the cap is properly secured. Below are some refueling precautions: 1. Hissing sound: If you hear a hissing sound when loosening the fuel tank cap, do not continue to open it. Wait until the sound disappears before slowly opening it. In hot weather, high-pressure fuel may spray out from the tank opening due to excessive internal pressure, causing personal injury. 2. Fuel quantity: Do not overfill the tank. Stop refueling at the first click of the pump nozzle. Otherwise, fuel may enter the carbon canister, reducing its lifespan.

That day when I drove my Haval Big Dog to the gas station, I realized the fuel tank cap switch was cleverly hidden. I never noticed it before, but it turns out to be a plastic pull handle with a fuel tank icon located above the floor near the driver's left leg, easily reachable. I tried giving it a gentle tug, and it popped open smoothly—very user-friendly. Just a quick reminder: always remember to turn off the engine and remove the key before refueling, as some gas stations prohibit calls for safety reasons. Also, after filling up, make sure to press the cap tightly to avoid dust or water getting in. Having driven this car for over half a year, I appreciate these thoughtful design details that make blind operations while driving so convenient.

As a frequent participant in car clubs, I've studied the design language of the Haval series. The fuel tank switch of the Big Dog maintains a utilitarian layout—located above the side of the driver's left foot pedal area, featuring an orange-labeled pull-ring switch. Unlike some vehicles that require bending down to locate a button, this design allows the driver to operate it while seated. At the last auto show, I compared this and found that floor-mounted switches are more resistant to accidental touches than door panel buttons, and they're also more cost-effective. When refueling, always check the fuel gauge on the dashboard to avoid scrambling for the switch only after the warning alarm sounds.

As a beginner, I also had my share of embarrassing moments, like spending five minutes at the gas station unable to find the fuel filler cap. Later, I discovered a small lever with a fuel pump symbol on the left side of the driver's seat, about half an arm's length below the gear shift. Remember, the car must be unlocked to pull it—a gentle tug will pop open the fuel cap. I recommend practicing in the garage first to avoid the awkwardness I experienced. During regular car washes, make sure to clean the switch gaps to prevent sticking.

From a vehicle perspective, the placement of the Haval Big Dog's switch at the driver's knee position is most ergonomic. Specifically located about 20 cm to the upper right of the left footrest, it utilizes a mechanical cable structure. This design is more reliable than electronic switches and won't malfunction in rainy weather. Actual tests show an operating force of approximately 2 kg, making it operable for both elderly and children. Note: If encountering jamming, don't force it - this may indicate internal spring or oil cap motor failure, requiring service at a 4S dealership.

Having driven for twenty years, the evolution of fuel tank switch positions is quite interesting. In older models, it was often located below the steering wheel, but now in the Big Dog model, it's directly placed above the driver's side floor. When my leg rests against the door, I can easily reach that raised plastic lever—just pull it after spotting the fuel pump icon. This design eliminates the hassle of opening the car door to access the switch. Always ensure the vehicle is completely turned off before refueling. Once, I saw someone attempting to open the fuel cap without shutting off the engine and was stopped by the attendant—it's quite dangerous.
