What are the six levels of waterlogged vehicles?

[AlainaMarie]

The six levels of waterlogged vehicles are: Level 1: Water just reaches the vehicle chassis, the floor may get damp, but the likelihood of significant water ingress is low, and the impact on interior electrical equipment is minimal; Level 2: Water reaches half of the wheels, at this point, due to the vehicle's incomplete sealing, water starts to enter the interior. For lower sedans, the water level inside may affect the seat adjustment motors and electrical components like heating and ventilation; Level 3: Water almost completely submerges the tires, at this stage, the water level inside will fully submerge the seat cushions and center console area, affecting a large number of electrical devices; Level 4: Water reaches the engine hood, the interior water level rises to the dashboard, and the headlights and engine intake pipes in the engine compartment start to take in water; Level 5: Water completely submerges the engine hood, at this point, almost all interior electrical equipment will be affected by the water; Level 6: Water submerges the roof, affecting the ceiling and sunroof module, with all interior components being submerged.
