Can Auto Hold and Engine Start-Stop Be Used Together?
2 Answers
Auto Hold and Engine Start-Stop can be used together. The auto start-stop function is used for stopping and starting the engine, while Auto Hold is used to stabilize the vehicle after stopping. These are two completely different functions that can operate simultaneously. Engine Auto Start-Stop automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move forward. On the other hand, Auto Hold is an automatic braking function that engages the handbrake for the driver when stopped at a traffic light, preventing the car from rolling backward. These are distinct functions, and some drivers may confuse them—for example, pressing the auto start-stop button when preparing to park, thinking it's the Auto Hold button, and forgetting to engage the handbrake, which can lead to the vehicle rolling.
I've driven many cars myself, and using auto hold and engine start-stop together works perfectly fine, with smooth coordination. For example, when stopping at a red light, the start-stop first turns off the engine to save fuel, and the auto hold immediately takes over to prevent the car from rolling away; when the light turns green, stepping on the accelerator immediately restarts the engine, and the car moves without any delay. During daily commutes in traffic, this significantly saves fuel and also reduces emissions for environmental protection. However, it's important to be mindful of battery stress, as frequent engine start-stop may lead to insufficient charging. I check my battery life every few months. On slopes or during heavy rain, it's best to manually switch to avoid slipping when starting. Overall, once you get used to it, it's very convenient and economical.
