What are the correct practices for one-button start?

To use the one-button start in a car, press the start button until the ACC light turns on, then press the start button again until it turns green. Below are specific reasons why the one-button start may not respond: 1. Steering wheel lock. The steering wheel lock is an anti-theft feature. When the car is turned off, turning the steering wheel from the centered position to a certain angle in one direction will lock it. In this state, the one-button start function will not work. To release the lock, turn the steering wheel left or right while pressing the engine start button to relieve tension. 2. The gear is not in P (Park) position. 3. Smart key battery is dead. When the smart key's battery is depleted, its transmission power is low, making it difficult for the car's sensors to detect it, preventing the one-button start from igniting the engine.
Press the brake pedal, ensure the gear is in P or N position, then lightly press the start button. Wait for the dashboard indicators to light up and the system to complete self-check before releasing the button. Never turn off the engine while in D or R gear—it damages the transmission. Also, turn off the air conditioning and audio system before shutting down to reduce current surge during the next startup, which benefits both the battery and starter. Temporarily stopping with N gear and handbrake is fine, but for shutdown, it's best to return to P gear. If the key fob is dead, pressing the rotary key against the start button allows emergency startup. Maintain at least 5-second intervals between each startup for safety.
The core sequence for one-button start is: Get in the car, press the brake, ensure it's in P gear, then hold the button until the engine starts. Remember to let the system self-check for 2-3 seconds before each start and check the dashboard for any warning lights. Avoid placing the key fob near your phone regularly, as electromagnetic interference may cause detection failure. If the engine won't start, try turning the steering wheel left and right to release the lock. Developing the habit of turning off all electrical devices before shutting down the engine is practical and can extend battery life. It's best to check the battery status annually, as weak batteries are more prone to causing issues with one-button start systems.
