Should Auto Start-Stop Be Turned Off When Driving in the Rain?

[VanTheo]

Auto start-stop should be turned off when driving in the rain. The reason for disabling the auto start-stop function on rainy days is to prevent water from being sucked into the engine when driving through deep puddles, which can cause the engine to stall. If the engine restarts in such conditions, it effectively means a second attempt to start the vehicle, and since water in the combustion chamber is incompressible, the engine could suffer severe damage or even be rendered useless. Therefore, it is advisable to use the auto start-stop feature cautiously during rainy weather. Below is some relevant information about auto start-stop: 1. Introduction: The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts the engine when it's time to move forward again. 2. Operation: When the car stops due to traffic congestion or at an intersection, the driver steps on the brake pedal and shifts to neutral, causing the engine to stop automatically. To restart, the driver simply needs to press the clutch or accelerator pedal to directly start the engine.
