The fuel tank cap door is located on the left rear side of the vehicle, and the small door lock is connected to the central locking system. When the door locks are open, pressing the right side of the small door will open it. Here are some additional details: 1. Opening conditions: The fuel filler door will only be locked when the vehicle doors are locked. When the doors are unlocked, pressing the fuel tank cap will cause it to pop open. When closing the fuel tank cap, locking the doors will also lock the fuel tank cap. Method to open the fuel filler cap: Slowly rotate the fuel filler cap counterclockwise to release pressure in the fuel tank before opening it. After refueling, reinstall the fuel filler cap and tighten it until you hear three "clicks." 2. Fuel requirements: Some models have specific fuel quality requirements. Using gasoline with a lower octane rating than specified may cause engine knocking. However, blindly using gasoline with a higher octane rating than required is also incorrect. High-octane gasoline burns more slowly. If used in an engine with a low compression ratio, it not only wastes money but can also cause delayed ignition, longer combustion times, and insufficient conversion of energy into power, resulting in sluggish acceleration during driving.

I've been driving my MG car for several years now, and the fuel tank cap switch is quite easy to locate. It's usually on the inner door panel on the driver's side. For example, in my MG ZS, the switch is located at the corner of the dashboard below the steering wheel, a small button or lever. When operating it, make sure to park the car on a level surface, turn off the engine, and then press it gently. Some older models like the MG TF might have it above the door handle, so it's good to familiarize yourself with the location. If you're a new owner and can't find it, don't worry—first check if the car doors are unlocked, as some models won't respond if the car is locked. If all else fails, refer to the user manual or ask a friend at the 4S store—safety comes first. Remember to clean the area around the switch during regular maintenance to prevent it from getting stuck. Also, take a quick glance before driving to ensure the fuel tank cap is securely closed to avoid any mishaps on the road.

The fuel door switch is ergonomically positioned on most MG models, including the new MG5, located on the driver's side door panel as a small lever or button near the seat. A simple press releases the fuel cap. If unresponsive, it might indicate a faulty switch or blown fuse—first check for any panel jams by gently pushing/pulling. Pro tip: Operate it after unlocking the car to prevent accidental activation. Avoid excessive force if the button doesn’t respond to prevent circuit damage. Keep the switch dry to prolong its lifespan. Bonus reminder: Always ensure the fuel cap is tightly closed after refueling to prevent vapor loss or hazards.

I think finding the fuel filler cap switch is quite straightforward, especially for everyday models like MG. The switch is usually located on the inner side of the driver's door, where you can easily feel a small button or lever by touch. For example, in the MG3, it's conveniently embedded under the door armrest for easy access. When refueling during daily driving, you can simply press the switch without much thought. Most cases of not finding it are due to first-time users overlooking its hidden position. Safety reminder: Operate it after parking and turning off the engine; never attempt to do so while driving. By the way, the switch design is typically dustproof and waterproof, but avoid hitting it with hard objects. If you're really unsure, just visit a 4S store for assistance.
