Do You Need to Keep Pressing the Brake for Auto Start-Stop?

[GrahamAnn]

Correct operation requires pressing the brake for the start-stop function to activate, allowing the engine to automatically shut off. When the brake is released, the start-stop system will restart the engine. After auto start-stop, an automatic transmission car remains in the D gear, and releasing the brake is sufficient. For manual transmission cars, pressing the clutch will start the vehicle, followed by shifting into first gear to begin moving. About Auto Start-Stop: 1. Usage Specifications: The function still requires the driver to follow proper driving practices to some extent. For example, the auto start-stop will not activate if the seatbelt is not fastened. Conversely, if the seatbelt is unfastened after stopping, the engine will not restart even if the brake is released or the accelerator is pressed. 2. Working Principle: When the car stops due to traffic congestion or at an intersection, and the driver presses the brake pedal to stop and shift gears, the Start/Stop system automatically detects that the engine is idling, no gear is engaged, the wheel speed sensors of the anti-lock system show zero, and the electronic battery sensor indicates sufficient energy for the next start, the engine will automatically stop rotating.

Having driven for many years and used many models with auto start-stop, I find this feature really convenient. The key point is, you don't need to keep pressing the brake pedal all the time. When stopping, just press the brake and the system automatically shuts off the engine to save fuel; as soon as you release the brake or lightly press the accelerator, it starts up immediately. So all you need to do is firmly press the brake at red lights or in traffic jams to keep the car still, and the engine will remain off. Some cars even have an auto-hold function, allowing you to completely release your foot after coming to a stop while the car stays stationary, and the start-stop still works. Related to this, the system operates using the battery and sensors, so if the battery ages, it may stop working, reducing the fuel-saving effect. In city driving, it can save over 10% on fuel, but remember to maintain and check it regularly.

I always pay special attention to environmental protection when driving, and the auto start-stop system is a great helper, eliminating the need to constantly press the brake. It stops the engine to reduce emissions when the brake is held down, and restarts the engine when released, with the entire process being fully automated. The benefit is that it can reduce fuel consumption by 15% in stop-and-go city driving, which is good for the planet and also saves effort. Relatedly, the system's operation depends on battery health, and it will automatically disable if the battery is low; check the dashboard indicator to ensure it's properly enabled. When driving an electric vehicle, similar technology is even smarter, making the overall driving experience greener and more sustainable.

When I first learned to drive, I also wondered about this issue. Actually, you don't need to keep pressing the brake all the time. Hold it down to stop the car, and the engine will shut off; lift your foot to release the brake, and it immediately starts up so you can go. The system is quite smart, but there's a slight vibration during startup that feels a bit odd at first—you'll get used to it after driving a few more times. Additionally, pay attention to the screen prompts in the car about the start-stop status, and avoid letting the system repeatedly engage during long traffic jams to prevent potential issues. Overall, it's easy to get the hang of.

The auto start-stop system is ingeniously designed internally, eliminating the need to continuously press the brake pedal. Maintain appropriate pressure by holding the pedal down, and the engine shuts off to save power; release the pressure to resume power delivery. During actual driving, sensors monitor the system status. If the battery charge is low or the temperature is abnormal, the system will temporarily suspend operation. Additionally, maintaining the electrical circuits is crucial. Regularly clean the terminal posts to prevent oxidation, ensuring reliable operation and maintaining daily driving efficiency.
