Driving on the highway with underinflated car tires is dangerous. Effects of low tire pressure: Low tire pressure increases tire body deformation, making the tire sidewalls prone to cracking. It also causes flexing movements, leading to excessive heat buildup, accelerating rubber aging, fatigue of the cord ply, and cord breakage. Additionally, it increases the tire's contact area with the ground, accelerating shoulder wear. Effects of high tire pressure: Excessive tire pressure overextends the tire cords, reducing the tire body's elasticity. This increases the load on the car during driving, and impacts may cause internal cracks or blowouts. High pressure also accelerates tread wear and reduces puncture resistance.

Can a Corolla use 5w40 engine oil?

A Corolla can use 5w40 engine oil. But there are some considerations: For brand new Corollas, it's recommended to use 0w20 engine oil as suggested by the manufacturer; For older Corolla models, 5w30 engine oil should be used; If the vehicle has been driven over 100,000 kilometers, 5w40 engine oil can be used. Introduction to engine oil: Engine oil, also known as motor lubricant, serves multiple functions for the engine including lubrication and friction reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of automobiles. Composition of engine oil: Engine oil consists of base oil and additives. The base oil is the primary component that determines the fundamental properties of the lubricant, while additives compensate for and enhance the performance limitations of the base oil, providing additional characteristics.

What Causes the Exclamation Mark on the Geely Vision X6 Dashboard?

When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: An exclamation mark inside a triangle indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Faults: A yellow gear with an exclamation mark is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Faults: An exclamation mark inside a circled parenthesis represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside a parenthesis is the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Faults: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
