There is a mechanical shift button in the car, usually labeled as SHIFT, located near the gear lever, which allows shifting from D/R gear to N gear. If you are on a highway or lack personnel and tools, you will have to seek emergency assistance.

I've been driving an LNG truck for several years, and adjusting the economy valve can save a lot of gas. The economy valve is essentially a device that controls fuel flow. When switched to economy mode, it limits high-speed injection to reduce waste. In the vehicle, you can simply press the ECO button on the dashboard or set it to the fuel-saving mode via the menu. Good driving habits are also important—start smoothly without sudden acceleration, and maintaining a speed of 60-80 km/h is the most economical. Remember to perform regular maintenance and check if the valve is clogged with carbon deposits. Cleaning it can improve efficiency. After my last valve adjustment, I saved hundreds of dollars in fuel costs per month—totally worth it. Also, when using the air conditioning, don't crank it up too high. Using the recirculation mode along with the fuel-saving mode works best. In short, driving steadily doubles the effect.
