Why Should Automatic Hold Be Turned Off When Reversing?
2 Answers
Automatic hold should be turned off when reversing to protect the transmission. Below is an introduction to automatic hold: 1. Concept: Automatic hold, also known as AUTOHOLD, refers to an automatic braking function. Once activated, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic handbrakes. For automatic transmission models, it also avoids frequent switching between D to N or D to P. 2. Working Principle: When the vehicle is temporarily stopped and needs to restart shortly after, the parking function is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque to determine any tendency for the vehicle to roll.
Friends who use auto-hold should turn it off when reversing—I learned this the hard way. When backing up, you often need to adjust your position, right? With auto-hold on, every time you press the accelerator, the car jerks to a sudden stop, making the movement choppy and uncomfortable. This can easily fluster beginners, leading to accidental hard presses on the accelerator. It’s even riskier in parking lots with curbs—the system might misjudge and slam the brakes, suddenly jolting the car and potentially damaging the undercarriage. A few days ago, I read a report about a driver who crashed into a wall while reversing because the auto-hold released abruptly after they pressed the accelerator too hard. Now, I’ve made it a habit to glance at the dashboard before reversing. If the yellow "A" indicator light is on, I turn it off with just a press of the button near the steering wheel. This is something to take seriously—safety is far more important than convenience.
