How to Use Auto Hold Function Most Effectively?

When passing through multiple traffic light intersections, activating the auto hold function can save more fuel. Below are relevant details about auto hold: 1. Introduction: It refers to an automatic braking function. After enabling this function, such as 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 reduces the need for frequent shifting between D to N or D to P. 2. Working Principle: When the vehicle is temporarily stopped and needs to restart shortly thereafter, the parking function is handled by the ESP-controlled braking system. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque, determining any tendency for the vehicle to roll. It then applies an appropriate braking force to the wheels to keep the vehicle stationary. This braking force is just enough to prevent the vehicle from moving without being too strong, ensuring that there is no severe lurch forward when pressing the accelerator again.
The auto hold function is really practical for daily driving. Personally, I'm used to pressing that button with an "A" to activate it right after starting the car. When waiting at traffic lights in the city, the system automatically holds the brake after coming to a complete stop - no need to shift gears or pull the handbrake, giving your foot complete freedom. Just lightly tap the accelerator to start smoothly when the light turns green, and it prevents rolling back on slopes. However, I recommend turning it off when reversing, as it might trigger frequent automatic braking. For prolonged stops, shifting to P gear reduces system load. Also, during heavy traffic when following too closely, temporarily disabling it can prevent delayed starts.
I think the most important thing about using auto hold is to turn it on and off flexibly. During rush hour, I keep it on the whole time, which allows me to relax both feet when stuck in traffic, and the effect of freeing up my right leg is obvious. However, it's crucial to turn it off before reversing into a parking space, as it can be frustrating when the car automatically brakes just after stepping on the accelerator. On rainy days with slippery roads, the response of auto hold may slow down, so extra attention is needed. After use, remember to check if the dashboard indicator light is still on. Once, I forgot to turn it off and drove for half an hour, but fortunately, modern car systems have intelligent protection.
The most practical feature of auto hold is the hill-start anti-rollback function. Last time when queuing at the steep exit of a shopping mall's underground parking lot, the car stayed firmly in place after releasing the pedal when stopped. It's recommended to use it in combination with the electronic parking brake: use auto hold for temporary stops, and engage the parking brake directly for long-term parking for added safety. Beginners might initially struggle with the throttle release force - practice gentle presses in an open area first. Avoid releasing the pedal before the car comes to a complete stop, as it may trigger insensitivity. Turning it off during traffic crawl actually makes operation smoother.
