Open the driver's side door of the BMW 730li. Engage the handbrake of the BMW 730li to prevent the vehicle from rolling. Pull the fuel tank cap switch located on the left side of the driver's leg area in the BMW 730li. Lift the fuel tank cap outward, unscrew the plastic cap of the fuel tank, and you can proceed to refuel.

When I first drove the BMW 730, I also wondered how to open the fuel tank cap. Actually, the method is quite straightforward: sit in the driver's seat, and there's an unlock button near the door handle on the left side. Press it gently, and the fuel tank cap will pop open automatically. This electronic design is for anti-theft and convenience, and all BMW 7 Series operate this way. I found that if the button doesn't respond, it's likely because the car doors aren't unlocked—you need to press the unlock button on the key first. If it still doesn't work, it might be a fuse issue; don't force it open to avoid damage. Always remember to turn off the engine when refueling to prevent hazards. Once you get used to it, you'll find it super practical—much more convenient than old-fashioned mechanical locks, and it also protects the car from unauthorized access. I recommend new drivers try it out more often; once it becomes a habit, it'll be effortless.

Refueling the BMW 730 is quite simple, and it only takes me a few seconds each time I do it myself: first, make sure the car is completely stopped and the engine is off, then unlock the doors. There's a clearly marked unlock button or lever on the left panel of the driver's seat—just press it to open the fuel tank cap. This design prioritizes safety, preventing accidental opening while driving. Once, I forgot to unlock it and couldn't open it no matter how hard I pressed, but later realized the key's remote unlock function did the trick. When refueling daily, always check the engine status and never attempt to open the cap while the engine is running. BMW models share similar mechanisms, and getting familiar with them can save a lot of hassle. For maintenance, regularly check if the button is responsive and avoid dust buildup to prevent blockage. After all, the fuel tank cap is crucial, and proper handling can extend its lifespan.

When I used to drive a BMW 730, I figured out the fuel tank opening method: sitting in the driver's seat, locate the unlock button on the left side, press it, and the fuel tank cap opens. This is much more convenient than the manual lock on older cars, as it pops open automatically without effort. Remember, the car must be in the unlocked state when operating; otherwise, the button won't work. If it doesn't respond, it might be an electrical issue—try turning the car off and on again. Or the cap might be stuck; give it a gentle push but don't force it. I think this design is quite user-friendly, ensuring both safety and efficiency. Before refueling, check if the engine is off—this is basic common sense. The fuel tank systems in the BMW series are very reliable; just keep them clean.
