The maximum wading depth of the BYD Han is 250mm. The wading depth of the BYD Han is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally speaking, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake of the BYD Han is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, be sure to turn off the auto start-stop function to prevent the vehicle from automatically restarting after stalling in the water, which could cause serious damage to the engine due to water ingress. Judge the underwater road conditions based on the passage of the vehicle ahead and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, and reference points such as the wheels and doors of other vehicles to judge the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not proceed recklessly; choose an alternative route instead.
