There are many warning lights in a car, and different lights indicate different issues: 1. The steering system warning light indicates a problem with the steering system; 2. The brake system warning light signals an issue with the braking system, such as low brake fluid level or the handbrake being engaged; 3. The electronic parking fault light means the system has malfunctioned, and the warning signal is illuminated; 4. The tire pressure warning light shows that the pressure in one of the vehicle's tires is either too low or too high; 5. The engine oil pressure fault light indicates an abnormality with the engine oil, such as insufficient oil level, worn oil pump, or abnormal oil pressure.

What Does Car Cruise Control Mean?

Car cruise control refers to a system used to maintain a constant speed for the vehicle. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer, which continuously adjusts the fuel delivery based on road conditions and the vehicle's driving resistance to maintain the set speed without the need for throttle operation. Cruise control is also known as a speed control system or autonomous driving system. Precautions for its use include: 1. Use on highways or fully enclosed roads; 2. Avoid using in rainy or snowy/icy conditions; 3. Avoid using on winding mountain roads, roads with too many curves, or poor-quality surfaces; 4. Avoid using when there is heavy traffic on the road.

What is the difference between a 3-cylinder and a 4-cylinder engine?

The difference between a 3-cylinder and a 4-cylinder engine lies in the number of cylinders: a 3-cylinder engine has 3 cylinders, while a 4-cylinder engine has 4 cylinders. The working principle of both 3-cylinder and 4-cylinder engines is as follows: 1. Intake stroke: The piston is driven by the crankshaft to move from top dead center to bottom dead center, while the intake valve opens and the exhaust valve closes; 2. Compression stroke: The piston moves from bottom dead center to top dead center, with both intake and exhaust valves closed; 3. Combustion and expansion stroke: Both intake and exhaust valves remain closed, the spark plug ignites, and the air-fuel mixture burns vigorously; 4. Exhaust stroke: The exhaust valve opens, and the piston moves from bottom dead center to top dead center, expelling the exhaust gases as the piston rises.

Can I choose not to use ETC?

If you have applied for ETC, you can choose not to use the manual lanes on highways. Since the manual lanes on highways are not equipped with ETC sensors, you can naturally use the manual lanes to take a card and pay. There are two ways to take a card in the manual lane: one is to receive the card from a professional staff member, and the other is for the driver to self-serve the card from the card dispenser. When passing through the toll station, it is essential to slow down and proceed in order, avoiding any congestion caused by cutting in line. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and driving license. If the application is not made by the owner, the agent must also bring their valid ID card. The photocopy of the driving license must include the page with the most recent annual inspection stamp; a bank card for deducting highway tolls; applicants must be between 18 and 60 years old; the vehicle must be under the applicant's name. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles accounts with the bank in the background, allowing vehicles to pay highway or bridge tolls without stopping when passing through toll stations. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Cost-saving: Reduces costs, decreases the frequency of vehicle starts and stops, minimizes wear and fuel consumption, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
