How Many Times Should You Press the One-Button Start for an Automatic Transmission?

You need to press it three times. The related introduction is as follows: 1. Press the start button once, and the ACC light will turn on (circuit connected); 2. Press the start button again, and the one-button start button will turn green, indicating the vehicle is performing a self-check; 3. After the vehicle completes the self-check, press the brake and press the one-button start button for the third time to officially start the vehicle. Why is a vehicle self-check necessary? The reasons are as follows: 1. The self-check is a process where, before the engine starts, the ECU is activated first, followed by the oil pump and fuel pump. After the ECU starts, it retrieves signals from sensors (pressure, temperature, speed, current, voltage) distributed throughout the vehicle. If any issues are detected during the self-check, they are displayed via warning lights in the alarm circuit; 2. Starting the vehicle without a self-check means the oil pump and engine start simultaneously. The fuel pressure in the engine hasn't reached the solenoid valve yet, the lubricating oil is still in the oil pan and hasn't reached the parts that need lubrication, and the computer controlling the engine operation is still starting up. The engine is forcibly driven by the electric motor, which can affect the vehicle's lifespan.
I'm a seasoned driver when it comes to cars with one-button start. Generally, I just press the brake pedal and lightly tap the start button—the engine fires right up. Never press the button multiple times without stepping on the brake, as that only switches the circuit to ACC or ON mode, allowing you to use electricity for things like the stereo but the car won't move. The design ensures safe operation by requiring the brake to be fully pressed and the vehicle to be in Park (P). If there's no response, first check if the key is inside the car or if the brake pedal is stuck and not fully depressed. Using this method long-term is hassle-free and protects the electrical system, preventing the battery from draining too quickly. The convenience of one-button start lies in its ability to quickly fire up the engine, unlike older cars where you had to turn the key multiple times. Remember, one press is enough—no need for extra actions that waste effort.
The core of the one-button start operation lies in safety control. After sitting in the driver's seat and firmly pressing the brake pedal, simply press the button once to start the engine. If the button is pressed without braking, the system will gradually enter ACC mode (supporting audio and other devices) or ON mode (dashboard lights on) instead of starting the car, preventing accidental starts that could lead to accidents. I recommend that drivers develop the habit of firmly pressing the brake and pressing the button once when preparing to start. If the startup fails, avoid repeatedly pressing the button, as it may indicate undetected keys or low battery power, requiring re-pressing the brake or checking the battery status. Correct operation extends the vehicle's lifespan and reduces unnecessary power consumption and mechanical wear.
