The wading depth of the Highlander is 455 millimeters. Exceeding this depth may affect the normal operation of the vehicle and, in severe cases, can lead to engine damage. The Highlander is a mid-size SUV under GAC Toyota. Taking the Highlander 2021 2WD Elite Edition as an example, its body dimensions are: length 4890 mm, width 1925 mm, height 1720 mm, with a wheelbase of 2790 mm. The Highlander 2021 2WD Elite Edition is equipped with a 2.0L turbocharged engine, delivering a maximum power of 162 kW at 5200-6600 rpm and a maximum torque of 350 Nm at 1800-4000 rpm.

I've been driving the Highlander in the city for several years, and the wading depth generally doesn't exceed 500 millimeters, which is about half the height of the wheels. This isn't an official hard limit, but it's fine for daily driving through puddles or small streams. The key is the position of the intake system—if water gets into the engine, it's totaled, and the repair costs are extremely high. On rainy days when the roads are slippery, I try to avoid deep water to prevent electrical shorts or rust on the chassis. Drive safely and pass through slowly, avoiding slamming the accelerator to prevent splashing. Tire condition and road conditions also affect safety. After wading, check the air filter or brakes to prevent mud and sand buildup from causing issues. In short, even though SUVs are tough, don't take unnecessary risks.

I often take my Highlander on road trips, and it can handle water depths of about 50 cm, which is sufficient for small streams and rivers. While its off-road capability isn't top-tier, the high ground clearance and air intake design provide stable wading performance. I remember last time during heavy rain crossing a ditch, I drove slowly without stalling. If the water is too deep, the engine warning light may come on, or even the electronic modules could fail. It's important to clean the chassis and tires after wading to prevent corrosion from mud and sand. I recommend measuring the water depth with a ruler before crossing—don't imitate reckless drivers who flip their cars. Safety first; no matter how good your vehicle is, don't push your luck.

I think it's safest not to exceed 500mm water wading depth with the Highlander. If the water is too deep, the engine might take in water, costing tens of thousands in repairs. Water damage to electrical systems is even more troublesome, and towing becomes difficult after stalling. Maintain a steady speed when wading through water, and avoid stopping or shifting gears. After crossing water, check the intake system and brake discs to ensure no residual water remains. From personal experience, SUVs don't have the same water wading capability as hardcore off-road vehicles. For daily driving, it's better to avoid or detour around water to prevent accidents that could harm both people and the vehicle.

I always pay attention to car maintenance. The official wading depth for the Highlander hasn't been disclosed, but tests show it can handle up to 500mm. Deep water poses significant risks, such as engine cylinder flooding or seal failure, requiring professional repairs. After wading, I immediately wash the car to remove mud from the undercarriage and prevent corrosion. The air filter also needs checking and should be replaced if wet. Frequent wading accelerates aging and leads to high repair costs. For safe driving, it's advisable to avoid deep water areas to protect the vehicle and extend its lifespan.
