To **save fuel**, it is important to **drive moderately** and avoid abrupt actions such as **hard braking** or **strong acceleration**. These practices help maintain more efficient fuel consumption.

- **Moderate driving**: By driving smoothly and steadily, excessive engine use is avoided, and fuel consumption is reduced. This is especially important in urban areas, where frequent speed changes and traffic jams can increase consumption.

- **Avoid hard braking and strong acceleration**: Hard braking and strong acceleration force the engine to work more than necessary, which increases fuel consumption. Maintaining a constant speed and anticipating traffic conditions can help avoid these situations.

- **Vehicle maintenance**: Although not directly mentioned in the correct answer, good vehicle maintenance, such as checking the ignition system and tire inflation, also contributes to efficient fuel consumption.

In summary, moderate driving without abrupt actions is key to saving fuel and keeping the vehicle in good condition.
