What Vehicle Functions Should Be Turned Off During Heavy Rain?
2 Answers
During heavy rain, the auto start-stop function should be turned off in vehicles, otherwise it may cause certain impacts to the vehicle. Auto Start-Stop: Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop during driving. Potential Hazards: If the water is too deep and the auto start-stop function is not turned off, the vehicle will automatically shut off and require the engine to restart. At this point, if the engine is started, the intake pipe suction will be relatively strong, potentially drawing water into the cylinders. This can lead to engine cylinder burning, piston damage, and other irreversible harm to the engine, possibly resulting in complete engine failure.
During heavy rain while driving, as an experienced long-distance driver, I always turn off the auto start-stop function first. Because if the engine accidentally stops and restarts in a waterlogged section, it's easy to suck water into the engine, causing water damage, and the repair costs are not cheap. I also turn off cruise control so that I can fully control the throttle and brakes myself, avoiding the danger of skidding or hydroplaning on slippery roads. Additionally, I pause entertainment systems like in-car music or navigation alerts to reduce distractions and focus better on road conditions. In heavy rain with blurred vision, I keep the headlights on and reduce speed to below 40km/h, trying not to follow other vehicles too closely. These habits have helped me safely navigate countless heavy rains, emphasizing safety first—never forget to turn off functions for convenience.
