Can Auto Hold and Auto Start-Stop Be Used Together?
2 Answers
Auto Start-Stop and Auto Hold can be used together. Here are detailed introductions to both functions: 1. Auto Start-Stop: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a traffic light) during driving. When it's time to move again, the system automatically restarts the engine. 2. Auto Hold: Auto Hold 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 prevents frequent shifting between D to N or D to P.
In my car, the auto hold and auto start-stop systems work perfectly together, making daily driving much more convenient. Every time I stop in traffic or at a red light, the system automatically activates: the hold function keeps the car stationary without needing to keep the brake pedal pressed, while the start-stop function turns off the engine to save fuel. When I press the accelerator to start moving again, the engine restarts, the hold releases, and the whole process is very smooth. This is especially useful for city driving, reducing fuel consumption by up to 15% and eliminating the worry of rolling back, enhancing safety. However, it depends on whether the car model supports it—many newer models from Mercedes-Benz and BMW feature this integrated technology. If the weather is too cold or the battery charge is low, the start-stop may automatically disable to prevent component damage. Overall, using these systems together saves effort and hassle, but avoid running the air conditioning too much as it can affect performance. It's recommended to regularly check the battery and system settings to maintain optimal condition.
