What is the maximum wading depth of the Highlander?

According to official information, the maximum wading depth of the Highlander is 455mm. Common tire specifications include 235/55R20, 235/65R18, and 235/55R20. The vehicle height is either 1750mm or 1715mm, with a total weight ranging between 1930-2115kg. It is available in two models: a 5-door, 7-seat SUV and a 5-door, 5-seat SUV. The maximum wading depth refers to the deepest water a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 300mm, while SUVs can handle deeper water, though it is still advisable not to exceed 500mm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 700mm, the Audi A4 has 320mm, the Volkswagen Sagitar has 700mm, the Land Rover Range Rover has 900mm, the Jeep Compass has 800mm, and the Lavida Plus has 300mm. SUVs generally have higher wading depths than sedans. Generally, when driving through water, vehicle owners should take different measures depending on the depth and the vehicle's characteristics, as follows: When the wading depth reaches the height of the exhaust pipe, it is still safe. Even if water enters the exhaust pipe, the pressure inside can expel it. As long as the engine is not turned off in the water, water will not flow back into the vehicle. When the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom of the car, which may lead to circuit failure, damage to critical electrical components, and prevent the car from starting normally. When the wading depth reaches the height of the intake pipe, it is extremely dangerous. Driving directly into such conditions can cause the vehicle to stall immediately, leading to permanent engine damage or rendering it unusable.
When I used to drive a Highlander, I often encountered waterlogged sections during the rainy season. The official claim for that vehicle is that it can wade through water up to 550mm deep, which is about half a meter. However, in practical use, I recommend not exceeding the height of the door sills, or else water might enter the engine intake or damage the electrical circuits. Once, I drove through a 30cm deep water area without any issues, but I had to maintain a slow and steady speed to prevent water from rushing into the engine. Exceeding 500mm is genuinely risky—it could lead to anything from stalling to complete engine failure. In daily driving, I avoid deep water puddles and always inspect the chassis and air filter after wading to protect my car. Although SUVs have some off-road capability, frequent water wading can shorten the lifespan of components, especially the electronic systems, which are prone to malfunctions. It's best to combine driving experience with safety first to avoid costly repairs.
As someone with years of car repair experience, I'm often asked about the Highlander's wading depth. It's designed for around half a meter of water, with an official rating of 550mm, primarily determined by the air intake position, underbody protection, and battery sealing. The elevated air intake prevents water from being sucked into the engine, which could cause hydro-locking. But don't blindly trust the numbers—fluctuating water levels or strong currents increase risks, potentially flooding the electrical box and causing short circuits. When fording water, don't exceed the middle of the wheel hubs, use low gear, and maintain steady engine RPM. The Highlander's ground clearance isn't particularly high, so without modifications, staying below 450mm is safer. Regularly inspecting waterproof seals helps nip potential issues in the bud.
