Tire kPa is a unit of air pressure, where one atmospheric pressure is approximately 100kPa. Below are specific guidelines for adjusting car tire pressure: 1. On roads with significant bumps, it's advisable to reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance high-speed driving, the tire pressure should not be too low; instead, increase it by about 0.2bar above the standard tire pressure's lower limit. 2. For new tires, the pressure can be increased by about 0.2bar above the standard. For old tires, appropriately reduce the pressure according to the standard, and if the wear is severe, set it to the lower limit of the standard tire pressure. 3. In winter, it's recommended to increase the tire pressure by about 0.2bar above the standard. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1bar lower than the standard to prevent high-temperature blowouts.

What is the maximum wading depth of the Prado?

According to official specifications, the Prado's maximum wading depth is 700mm. It commonly features 265/60R18 tires, has a vehicle height of 1890mm, a curb weight of 2285kg, and is a 5-door, 7-seat SUV. Maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, sedans have a maximum wading depth not exceeding 300mm, while SUVs can handle deeper water but should ideally not exceed 500mm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 700mm, the Audi A4 320mm, the Volkswagen Sagitar 700mm, the Land Rover Range Rover 900mm, the Jeep Compass 800mm, and the Highlander 455mm. SUVs generally have higher wading depths than sedans. Generally, when driving through water, vehicle owners should take different measures depending on the water depth and the vehicle's specifications, as detailed below: If the water reaches the exhaust pipe height, 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, no backflow will occur. 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 may lead to short circuits, damaging critical electrical components and preventing the car from starting. If the water reaches the air intake height, it is extremely dangerous. Driving directly into such deep water may cause the engine to stall, leading to permanent damage or rendering the engine unusable.
