What is the function of Auto Hold?
4 Answers
Auto Hold refers to an automatic braking function. After activating this feature, there is no need to pull the handbrake when stopping at traffic lights, simplifying the operation by avoiding the use of the handbrake or electronic parking brake. For automatic transmission models, it also eliminates the need for frequent shifting between D gear and N gear or D gear and P gear. The Auto Hold function does not use additional components; it still utilizes the same braking mechanism that executes the brake pedal commands. When the ESP control system detects that the vehicle has come to a complete stop, the electronic parking function is activated, replacing the foot brake. If the vehicle remains stationary for a certain period after the electronic parking is engaged, the control system will automatically activate the electronic parking brake, releasing the Auto Hold function.
Auto Hold is a lifesaver for someone like me who gets stuck in downtown traffic every day. At a red light, just press the brake pedal firmly until the green 'AUTO HOLD' indicator lights up on the dashboard, then you can release your right foot—the car stays perfectly still without any rolling. When starting off, a light tap on the accelerator automatically releases it, which is way more convenient than traditional electronic parking brakes. The best part? No need to keep your foot on the brake during half-hour traffic jams—your ankles finally get a break! Just a heads-up: use it cautiously in rainy weather. Last time during a heavy downpour, my tires slipped for half a second when starting on a slope, probably due to the wet road. Remember, turning it off is simple too—just press the button to turn off the indicator light.
When I first bought the car, I also wondered what the purpose of this function was until I drove on a mountain road and instantly fell in love with it. When waiting for tourists on steep slopes, turning on the auto-hold means no need to desperately press the brake or fumble with the handbrake—my right foot can rest comfortably on the carpet. The throttle response has a 0.5-second delay to prevent accidental presses, but it's not a big deal. One thing to note is that it's better to turn it off when reversing into a parking space; otherwise, you have to tap the throttle every time you adjust, and poor control could lead to hitting the wall. Additionally, pairing it with auto start-stop saves more fuel. The braking force remains even when the engine is off, so you can just go when the light turns green.
Auto Hold essentially helps you by applying the brakes. In traditional cars, you must press the brake pedal to prevent rolling when in D gear, but now the system automatically locks the brake calipers and releases the brake via electronic signals when you're ready to move. Once, I drove to pick up my child and parked on a slope at the school entrance to buy a drink. When I returned, the car hadn't moved an inch. This feature requires the seatbelt to be fastened to activate, which incidentally cured my habit of not wearing it. Upgrading an older car might require replacing the electronic parking brake module, but most new cars come with it as standard.
