How to Drive an Automatic Car Through Water?

At this point, pull over and observe how other vehicles are passing through. You can use an umbrella, branches from the roadside, or walk through the water yourself to test the depth. This will help estimate whether the vehicle can pass. As long as the air intake doesn't take in water, the vehicle won't stall and can proceed. If it's not suitable, do not force your way through the water.
I've driven through waterlogged roads many times, and the key is to stay steady. First, pull over and stop, then visually assess the water depth—generally, it shouldn't exceed the midpoint of the wheel hub, or the risk of water ingress increases. For automatic transmission vehicles, avoid using D gear; switch to a lower gear like L or S, maintaining engine speed around 2000 RPM. Gently press the accelerator to move slowly—no sudden acceleration or braking, as splashing water could flood the engine. Keep the steering wheel steady while crossing, maintaining a constant speed without changing lanes or hesitating. After passing through, find a flat spot to stop, turn off the engine briefly to let the exhaust pipe drain, then test the brakes for responsiveness (braking distance may be longer on wet surfaces). If the water level feels high and the car starts floating, stop immediately and call for help—safety first, never force your way through deep water.
Last week I drove my car through muddy rural roads, where the water wasn't deep but still quite intimidating. Gotta say, automatic transmission is truly worry-free—just switch to manual mode and select 1st gear. When entering water slowly, don't panic; maintain light throttle pressure, and the car will glide through smoothly. Keep speed around 5 km/h—going too fast may cause water to backflow into the exhaust pipe. After exiting, immediately inspect the undercarriage, clear mud to prevent clogging, and pop the hood to check if the air filter got wet. If damp, replace it to avoid engine issues. For road trips, always keep a toolkit handy with ropes and a first-aid kit in case you get stuck and need emergency towing.
When taking family out, encountering rainy roads is common, and safety is paramount. First, assess the water depth; the baseline is not exceeding half the wheel height. Automatic transmissions can pass in D gear but should do so slowly. Turning on the AC and turning off the fan can reduce the risk of water entering the engine. Drive into the water at a steady speed, maintaining a straight line to avoid skidding—stable car, safe people. After passing, test the brakes with a couple of quick stops to ensure they're functioning properly—brake discs are prone to rust after wading, affecting performance. Regular maintenance can prevent accidents.
