What is the Auto Start-Stop Function in Cars?
2 Answers
Auto Start-Stop Function refers to the engine's automatic start-stop system. It 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 again. The Auto Start-Stop Function, abbreviated as STT, is an intelligent fuel-saving system that controls the engine's start and stop operations. How to use the Auto Start-Stop Function: 1. For manual transmission vehicles, shift to neutral, engage the handbrake, and release the clutch to automatically shut off the engine. Pressing the clutch again will automatically restart the engine. 2. On steep slopes, it is advisable to avoid using the auto start-stop feature as brief auto start-stop cycles may lead to insufficient brake assistance.
I remember paying special attention to the start-stop feature when driving my car equipped with it. Basically, the engine automatically shuts off when stopping, such as at a red light, and restarts immediately upon releasing the brake or pressing the accelerator, saving a significant amount of fuel. In city driving, my average fuel consumption dropped from 8 liters per 100 kilometers to around 7.5 liters, saving money in the long run and being more environmentally friendly. However, the startup vibration can be a bit annoying, especially in congested areas where the repeated starts and stops feel more abrupt. Cold starts in winter also accelerate battery aging. Overall, it's practical but takes some getting used to, with battery lifespan being a key factor—opting for a reinforced model helps. Driving habits also play a role: try to keep it enabled during smooth traffic and disable it in heavy congestion to avoid unnecessary operations. From experience, I've learned that regular system health checks are crucial to prevent unexpected breakdowns and the trouble they bring.
