Automatic transmission car one-button start correct method is: first ensure the key is inside the car, press the brake, then hold the start button to start the vehicle, shift to D gear, release the handbrake, and release the brake to start moving. Before getting in the car, observe the surroundings to ensure safety, then enter the car. After sitting down, remember to fasten the seat belt. Automatic transmission cars do not require the driver to manually shift gears; the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L. Driving an automatic transmission car using the parking gear P, reverse gear R, neutral gear N, and drive gear D can meet the needs of general driving. However, if encountering some special driving conditions, other functional gears may be required.

After driving automatic transmission cars for so many years, I've learned that the key to one-button start is developing muscle memory: first fasten the seatbelt and press the brake pedal after getting in the car, when all dashboard lights will illuminate for self-check - don't rush to press the button again immediately. Wait until most self-check lights go off, then firmly press and hold the start button while keeping the brake pedal fully depressed until the engine completely starts before releasing. The most common mistake beginners make is shifting gears immediately after ignition - it's safest to wait until the tachometer stabilizes below 1000 rpm before shifting to D. Once I was in a hurry and started without waiting for self-check, which triggered the engine warning light - the mechanic said it was caused by electrical system disturbance, proving those few seconds of patience are crucial. When parking, don't take shortcuts by pressing the stop button directly either - always shift to P and engage the handbrake first to protect the transmission.

During the last test drive, the salesperson shared a cool tip: For cars with keyless entry, if the key isn't detected near the driver's seat, pressing the start button while stepping on the brake won't work, and the dashboard will display a key icon. The correct procedure is to keep the key in your pocket or place it in the cup holder's induction area, sit firmly, and press the brake pedal firmly with your right foot. At this point, the start button will change from orange to green, and a single press will start the car. For cars with auto start-stop, extra caution is needed when restarting. If the engine stops during traffic congestion, gently release the brake pedal to avoid a sudden ignition and jerky movement, which can be quite startling. My friend once rear-ended someone because of this, so now I always advise her to turn off the auto start-stop function as soon as she gets in the car.

Actually, the logic of one-button start varies among different car brands. For example, Japanese cars generally require you to press the brake pedal deeply to start the engine, while German cars only need a light press. Once, when I was driving my friend's Volkswagen, the engine started as soon as I touched the brake, almost causing me to hit the garage wall. The safest method is to press the brake pedal all the way down before pressing the button, then wait for the engine sound to stabilize for three seconds. Also, when temporarily stopping to wait for someone, it's more fuel-efficient to shift to N (Neutral) and engage the handbrake instead of shifting to P (Park). To start again, simply press the brake and shift to D (Drive). Remember to wait until the tachometer needle drops back to the idle range before applying throttle, as this reduces transmission shock. Statistics show that starting under load is the most damaging to the starter motor, so it's best to turn off the air conditioning and audio system before shutting down the engine.
