How to reset the Mazda CX5 start-stop system?

The automatic start-stop system of the Mazda CX5 cannot be reset, as this system has its own activation conditions. The automatic start-stop system determines whether to activate based on factors such as battery charge, whether the air conditioning is turned on, and whether the engine has reached normal operating temperature. If the switch is turned off, the automatic start-stop system will not activate under any circumstances. The Mazda CX5 is a compact SUV with dimensions of 4555 mm in length, 1842 mm in width, and 1685 mm in height, with a wheelbase of 2700 mm. The Mazda CX5 is equipped with two naturally aspirated engines: a 2.0-liter engine and a 2.5-liter engine. The 2.0-liter naturally aspirated engine produces 155 horsepower and a maximum torque of 200 Nm, while the 2.5-liter naturally aspirated engine delivers 196 horsepower and a maximum torque of 252 Nm.
I also encountered issues with the start-stop system not working properly when driving my CX-5 before, and figured out a manual reset method. First, don't start the engine - directly turn off the start-stop button, then cut off all power and lock the doors, waiting about ten minutes for the system to completely power down. Next, reopen the door and start the ignition, but don't immediately turn on the AC or headlights - let the engine idle for three minutes before pressing the start-stop button again. The whole process is somewhat like force-restarting a phone, allowing the vehicle's computer to relearn driving habits. If it still doesn't work after this procedure, it might be because the battery charge is below 70% - after all, the start-stop system is particularly sensitive to voltage requirements, and the battery may need replacement. Normally, turning off the AC before shutting down the engine can help extend the start-stop system's service life.
Resetting the start-stop function is actually quite simple. I usually use the double-safety reset method. First, drive the car to a flat area and park it steadily, then turn off the start-stop switch and shut off the engine before getting out of the car. Wait patiently for about seven to eight minutes. During this time, you can check the positive and negative terminals of the 12V battery to ensure there is no green oxide affecting conductivity. When restarting the car, keep the steering wheel straight, and after the tachometer stabilizes, turn on the start-stop button. If the dashboard displays a yellow start-stop warning light, it means you need to connect a diagnostic tool to clear the fault code. I've used this method five or six times, and it works every time the system malfunctions. One thing to note is not to perform this operation immediately during high summer temperatures; it's safer to wait until the engine cools down a bit. Also, manually turning off the start-stop function in city traffic jams can actually save more fuel.
