What Causes the Malfunction Indicator Light to Illuminate in a New Car?

New car malfunction indicator light illumination can be attributed to the following reasons. 1. When the ignition switch is turned on, dashboard indicator lights will illuminate as part of the vehicle's self-diagnosis system and should automatically turn off after a period. 2. Engine malfunction light indicates poor combustion condition, engine knocking, substandard fuel quality, or excessive engine carbon buildup. 3. Battery warning light signals battery depletion/failure or power system malfunction. 4. Oil warning light indicates insufficient oil level, excessive engine temperature, improper oil selection, or blocked oil passages. 5. Tire pressure warning light suggests tire puncture/leakage or damaged tire pressure sensor. 6. Brake system warning light indicates engaged parking brake, ABS failure, non-compliant brake fluid, or brake system abnormality. 7. Coolant temperature warning light shows excessive engine temperature, insufficient coolant, thermostat failure, or damaged coolant temperature sensor.

Will adding too much engine oil affect the engine?

Adding too much engine oil can have several negative effects on the engine, including the following aspects. 1. Increased fuel consumption and reduced power. If too much oil is added, the oil level becomes too high, causing a significant portion of the crankshaft to be submerged in the oil. This increases rotational resistance as the crankshaft churns the oil. 2. Accelerated carbon buildup and damage to certain car components. As the crankshaft churns the oil, a large amount of oil can be splashed onto the pistons and cylinder walls, entering the combustion chamber and burning. Carbon buildup has long-term effects on power and fuel efficiency. 3. Oil leakage from the crankshaft oil seal and shortened oil lifespan. The excessive churning of oil increases pressure inside the crankcase, which acts on the crankshaft oil seal, accelerating its aging and deformation, ultimately leading to leaks. It also speeds up the oxidation and degradation of the oil, shortening its service life. 4. Worsened exhaust emissions, severely affecting the lifespan of the catalytic converter, and may even directly damage it.

What does the ECO on the car dashboard mean?

The ECO on the vehicle dashboard refers to the car's economical driving mode function. ECO is an English abbreviation formed from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economical mode has been activated. The Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder function. The Eco mode automatically evaluates your driving behavior; if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most vehicles employ the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to enable the Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. In such scenarios, activating the Eco mode would not only fail to demonstrate its fuel-saving characteristics but also affect the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or in N/P gear and manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such cases.

Can High Beam Headlights Be Used on Highways?

High beam headlights can be used on highways. The specific reasons are as follows: 1. According to Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," high beam headlights can be used on roads without street lighting or with poor illumination. When the vehicle speed exceeds 30 kilometers per hour, high beams should be prioritized. On highways, where the minimum speed is 60 kilometers per hour, using high beams is both reasonable and legal. 2. High beam headlights can effectively distinguish objects. When driving at night, high beams illuminate a longer distance, providing the driver with a clearer field of vision. Night driving limits the driver's visibility, making it difficult to judge road conditions and surroundings outside the vehicle. Therefore, using high beams on highways at night helps in better identifying objects. 3. It helps avoid missing exits. At night, a driver's visibility is worse than during the day. If low beams are used, the field of vision becomes shorter, often leading to missed highway exits. Using high beams provides a broader view, reducing the likelihood of taking the wrong exit. 4. High beams help spot obstacles on the road. Drivers familiar with highways know that speeds are generally high. If cargo falls off a truck ahead or there are road obstacles at night, high beams allow the driver to observe the road ahead more clearly, providing enough time to avoid hazards. Using low beams in such situations increases the risk of accidents. 5. When driving at high speeds, high beams illuminate a longer distance compared to low beams. The recognition distance and confirmation distance—the distance at which you can see and clearly identify objects ahead—are greater with high beams than with low beams.

How Often Should Windshield Washer Fluid Be Replaced?

Windshield washer fluid in cars generally does not need to be replaced; simply refill it when it runs out. Below is relevant knowledge about the use of windshield washer fluid: 1. When owners notice the washer fluid level is low or the fluid has run out, they can add it themselves. Refilling windshield washer fluid is very simple: just open the engine hood, locate the cap of the washer fluid reservoir, open the cap, and add the fluid. 2. In winter, it is essential to use washer fluid with a lower freezing point; otherwise, the fluid may freeze due to low temperatures. When liquid freezes, its volume expands, which could potentially damage the washer fluid reservoir. Always refill the washer fluid promptly when it runs out, as it is crucial for keeping the windshield clean. After adding the fluid, make sure to securely close the cap to prevent dirt from entering the reservoir. 3. If the washer fluid is low, avoid using water as a substitute, as water contains impurities that can easily clog the washer nozzles. Typically, filling a car's washer fluid reservoir requires about four liters of fluid. When purchasing washer fluid, buy according to the reservoir's specified capacity. Avoid buying low-quality washer fluid, as using it may accelerate the aging of the windshield wipers.

What Are the Causes of Tire Blowouts?

Causes of tire blowouts include low tire pressure, overinflation, incorrect installation, lack of proper maintenance, tire wear and aging, sidewall bulges, manufacturing defects, and severe impacts. Below are additional details: Measures to prevent tire blowouts: Replace tires in a timely manner, perform wheel alignment and tire balancing, rotate front and rear tires, maintain proper tire pressure, and avoid speeding. How to handle a tire blowout: Hold the steering wheel firmly, adjust the direction gently; avoid sudden or repeated steering movements, do not slam on the brakes, and wait for the vehicle to slow down gradually before making gentle steering adjustments; place a warning triangle behind the vehicle to prevent secondary accidents.
