How to completely turn off the auto start-stop function in the 2020 Nissan X-Trail?
3 Answers
2020 Nissan X-Trail's auto start-stop function cannot be completely turned off. However, during use, you can prevent it from activating by adjusting the depth of brake pedal pressure or slightly turning the steering wheel. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when you need to proceed. Taking the 2020 Nissan X-Trail 2.5L XL CVT 4WD Intelligent Leading Edition as an example, its body dimensions are 4675mm in length, 1820mm in width, and 1722mm in height, with a wheelbase of 2706mm. The body structure is a 5-door, 5-seat SUV, featuring a front MacPherson independent suspension and a rear multi-link independent suspension.
I've been driving a 2020 X-Trail for several years and find the auto start-stop function quite annoying, especially when driving in the city where it frequently shuts off and restarts the engine during stops, creating strong vibrations. To completely disable it, the regular manual button only turns it off for the current trip, requiring a press every time the car starts. For permanent deactivation, the manufacturer doesn't provide a setting option as it would violate eco-design principles. I consulted a 4S店, and they mentioned that professional tools could reprogram the system to disable it, but this might affect the vehicle warranty or onboard computer functions. I didn't dare to try it myself—I heard that after modification, the battery monitoring system might give false alerts. They suggested first using an OBD scanner to check for potential fault codes. For long-term use, sticking with the manual button is safer, and you'll get used to it over time.
As a DIY enthusiast car owner, I've researched how to permanently disable the X-Trail's auto start-stop function. The simplest way is pressing the start-stop button near the steering wheel each time you drive, but this isn't permanent. To disable it forever, you need to connect a diagnostic tool via the OBD port, such as a programmer bought online, to access system settings and deactivate the start-stop module. I've personally succeeded with this method, but the process carries risks - improper operation may trigger software errors or even damage the car battery. Remember to consult a professional technician rather than attempting it recklessly. While auto start-stop is designed for fuel efficiency and emission reduction, disabling it sacrifices some convenience but brings more quietness. Don't blindly follow forum tutorials for modifications - protecting your vehicle's electrical system should always be the priority.
