What does 'bar' appearing on the car mean?

[CameronLee]

When 'bar' appears on the car, it indicates low tire pressure. Solutions: 1. Check if the tire is leaking air (the 'bar' light typically comes on with slow leaks). If there's a leak, immediately repair or replace the tire; 2. If unsure about air leakage, simply inflate the tire and observe if the pressure normalizes; 3. If the above issues are resolved, restarting the engine will make the 'bar' display on the dashboard automatically disappear. Tire pressure is crucial for tires - it must not be too high or too low. If the pressure is too low, the tire may experience wave-like deformation during high-speed driving, increasing the risk of a blowout and reducing tire lifespan. If the pressure is too high, it reduces the contact area between the tire and the ground, affecting the car's handling and driving stability.
