What is the maximum wading depth of the Highlander?

According to official information, the maximum wading depth of the Highlander is 45.5 centimeters. Common tire specifications are 235/55R20 and 235/65R18, with a body length of 4965mm. The vehicle is equipped with an E-CVT continuously variable transmission and features a 5-door, 7-seat SUV body structure. The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 centimeters, while SUVs can handle slightly deeper water, though it's best not to exceed 50 centimeters. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 centimeters, the Audi A4 has 32 centimeters, the Volkswagen Sagitar has 30 centimeters, the Land Rover Range Rover has 90 centimeters, and the Jeep Compass has 48 centimeters. SUVs clearly surpass sedans in maximum wading depth. Generally, when driving through water, vehicle owners should take different measures based on the water depth and the vehicle's characteristics, as follows: If the water reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel it. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the water reaches the door frame height, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which could lead to circuit failures, damaging critical electrical components and preventing the car from starting normally. If the water reaches the height of the air intake pipe, it is extremely hazardous. Driving directly into such conditions may cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.
When I previously drove a Highlander through heavy rain and waterlogged sections, it could generally safely pass through shallow water up to half a wheel deep, approximately 500mm, but not exceeding this depth. The Highlander isn't a hardcore off-road vehicle; its water wading capability mainly depends on the air intake located at the front of the vehicle. If water enters, it can damage the engine computer. Remember to check tire seals before the rainy season and avoid risking deep puddles. Always pay attention to the depth and flow rate of water while driving—if the current is too strong, don't force your way through. In case the engine stalls due to deep water, do not restart it immediately; instead, have it towed for repairs.
I have researched the wading capabilities of many SUVs. The Highlander does not have official data, but according to unofficial tests, it can drive stably in water up to 500mm deep. Potential impacts of wading include water entering the air filter and electrical short circuits. For daily use, it is recommended to pass through waterlogged areas slowly to avoid surges. Compared to vehicles like the Prado, the Highlander is more city-oriented, and wading is not its strong suit. During regular maintenance, have technicians inspect the sealing rings on the chassis to help anticipate risks.
