What to Do When the Exclamation Mark Warning Light on the Vehicle Dashboard Illuminates?

1 Answers

When an exclamation mark appears on the car dashboard, there are five possible scenarios: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting malfunction. Below is a detailed analysis of these five situations: General Malfunction: A triangle with an exclamation mark inside indicates a general performance or component malfunction if this symbol lights up. Common issues include parking sensor failure, fuel cutoff 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 malfunction. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Brake System Failure: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal Tire Pressure: A horizontal line with parentheses below and an exclamation mark in the middle signifies the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the vehicle's tire pressure and restore it to the normal range. Lighting Malfunction: A yellow bulb with an exclamation mark is the lighting malfunction indicator, alerting that a vehicle light has failed. 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.

What size tires fit 16-inch wheels?

16-inch wheels can be fitted with tires of specifications such as 185/55r16, 195/50r16, 195/55r16, 205/55r16, 205/60r16, and 205/65r16. It is recommended to match the original tire specifications of the vehicle. If you need to change the tire specifications, you must go to a professional modification shop for tire upgrades or consult the car manufacturer. Tires are rubber products and will age over time, so they need to be replaced regularly. Under normal conditions, tires installed on a car can last for four years, but depending on individual driving habits, it is recommended to replace the tires every four years.

Can a cracked wheel hub still be used?

A cracked wheel hub cannot be used anymore. Once cracks or gaps appear on the wheel hub, it can easily lead to slow air leakage in the tire. Additionally, the car may experience shaking while driving, which is quite dangerous. The wheel hub is a crucial component of a vehicle, responsible for ensuring safe and normal operation. Cracks in the wheel hub pose a safety hazard to the vehicle. The wheel hub is a cylindrical metal part that supports the tire from the inside and is mounted on the axle. It is also known as the rim, steel rim, or wheel. Wheel hubs can generally be divided into two types: painted and plated. Plated wheel hubs further include silver plating, water plating, and pure plating, among others.

Do the Engine and Transmission Use the Same Oil?

Engines and transmissions do not use the same oil. The engine uses engine oil, while the transmission uses transmission fluid. Engine oil is the lubricant for the engine system, possessing properties such as oxidation resistance, wear resistance, and anti-corrosion. On the other hand, transmission fluid primarily serves to keep the gear system clean and extends the service life of internal transmission components. Due to the differences in structure and operating environments between the transmission and the engine, transmission fluid cannot be used as engine oil, nor can engine oil be used as transmission fluid. The engine has higher requirements for the oil's high-temperature resistance, oxidation resistance, and cleaning properties. Although the transmission operates at relatively lower temperatures, its internal components still require lubrication. Transmission fluid helps extend the lifespan of gears and offers low-temperature resistance.

What Does Vehicle Destruction Mean?

Vehicle destruction certification refers to the demolition and disappearance of a motor vehicle, which means the vehicle is scrapped. More details about vehicle destruction are as follows: 1. To deregister a vehicle due to destruction, a destruction certificate must be obtained from the relevant authorities: The certificate requires complete documentation, and it is illegal to privately dispose of or dismantle and sell a scrapped vehicle, as national regulations prohibit such actions. 2. Conditions for obtaining a vehicle destruction certificate: (1) If the vehicle is destroyed due to a natural disaster, the local government of the incident area must issue the destruction certificate. (2) If the vehicle is destroyed by fire, the local fire department must issue the destruction certificate. (3) If the vehicle is destroyed in a traffic accident, the local traffic management department must issue the destruction certificate. (4) If the vehicle is stolen and not recovered after reporting the theft, the local police station or public security department must issue the destruction certificate.

Can Inner Tubes Be Installed in Tubeless Tires?

Tubeless tires can accommodate inner tubes. As long as there are no damaged or abrasive areas inside the original tubeless tire that could wear the inner tube, you can directly install the inner tube without adding a liner. Adding a liner may cause tire distortion and vehicle wobbling during driving. It's also important to note that installing an inner tube will, to some extent, wear the valve area of the original tubeless tire, potentially causing issues when switching back to tubeless tires in the future. Below are precautions for using tubeless tires: 1. Maintain the specified tire pressure. Tubeless tires are made of high-quality rubber with excellent elasticity and flexibility, adapting well to a wide range of pressures. Even at high pressure, they don't feel as hard as conventional tires, so always use a pressure gauge to check. Unlike conventional tires, tubeless tires generally don't lose air unless punctured. Therefore, always use a pressure gauge to check and maintain the specified pressure—never rely on manual feel to decide whether to add air. 2. Not suitable for overloading. Tubeless tires are wear-resistant but not pressure-resistant. Some heavy-duty trucks use tubeless tires for the steering wheels while keeping conventional steel-belted tires for the drive wheels to ensure load capacity and improve driving comfort. 3. Avoid punctures from sharp objects and contact with acids, alkalis, or oil, as these can accelerate rubber degradation. Keep the tires clean to prevent rubber aging and extend their lifespan. 4. Tubeless tires perform well on asphalt and concrete roads, maintaining strong traction even on wet surfaces and offering good stability. However, they have poor traction and stability on dirt roads, especially muddy ones. Motorcycles with tubeless tires are best suited for urban use and not recommended for off-road or rural dirt roads.
