Is it necessary to shift to N gear when using auto hold?

Whether to shift to N gear when using auto hold depends on the specific situation: 1. If the parking time is short, it is not necessary to shift to N gear; 2. If the parking time is long, it is necessary to shift to N gear. Auto hold refers to an automatic braking function. After activating this function, it can simplify operations by avoiding the use of handbrakes or electronic handbrakes. For automatic transmission models, there is no need to frequently switch between D to N or D to P. The function of auto hold is to prevent the vehicle from rolling, which is suitable for uphill, downhill, or frequent starts and stops. The working principle of auto hold is: the controller provides accurate parking force through the slope sensor. When starting, the parking control unit calculates the information provided by the clutch distance sensor, clutch engagement speed sensor, and accelerator pedal sensor. When the driving force is greater than the driving resistance, the parking brake is automatically released, allowing the car to start smoothly.
Having driven automatic transmission cars for years, the auto-hold function is truly considerate. At red lights or during brief traffic jams, the car automatically holds the brakes, staying firmly in place without rolling – no need to shift to N at all. Shifting to N is redundant, requiring an extra operation of the gear lever and adding unnecessary wear to the transmission, especially during city commutes with frequent traffic lights where constant gear changes are a hassle. However, for longer stops, say over a minute, I prefer shifting to P, which reduces engine load, saving fuel and keeping things quiet, without affecting auto-hold activation. The key is adapting flexibly to the situation: auto-hold for short stops, P for longer ones – safe and efficient. Always check that your car’s auto-hold works properly, and avoid idling too long in D to protect the transmission. Driving smart with less manual effort naturally makes things easier.
As an office worker commuting in the city every day, the auto hold feature is a lifesaver. When encountering traffic lights, the car stops and the brakes lock automatically, saving me from keeping my foot on the pedal. There's no need to shift to N (neutral) gear at all. N gear is neutral, and switching to it is cumbersome. You have to shift back to start, which affects convenience and can distract you, potentially leading to accidents. I usually just let the auto hold do its job, unless I'm waiting in a long queue for two or three minutes, then I might shift to P (park) gear to relax. When auto hold works well, shifting to N gear is completely unnecessary—better to save your energy for focusing on the road. By the way, some cars have slow auto hold responses, especially on slopes, so it's good to double-check that the car isn't moving before releasing the pedal. In short, enjoying the convenience of technology and reducing unnecessary steps is the most comfortable way to drive.
After years in auto repair, I always emphasize to car owners that with the auto-hold function activated, there's no need to additionally shift to N gear. The system handles braking during brief stops while keeping the transmission in D gear with minimal pressure. Shifting to N gear frequently changes gear states, actually increasing friction and wear. However, if parking exceeds one or two minutes, it's advisable to shift to P gear to reduce engine load and avoid idling wear on the oil circuit. Always check the vehicle manual to ensure proper operation and avoid bad habits that may lead to future issues like increased fuel consumption or premature transmission failure. These small oversights can accumulate into costly repairs later on.
