How to Use Lights When Driving at Night?

What causes the engine warning light to sometimes come on and sometimes go off?

Engine warning light flashing indicates that there is a problem with the engine, and the issue is relatively serious, requiring immediate inspection. The specific reasons may include the following 7 possibilities: Sensor malfunction: The sensors mentioned here include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine warning light. Fuel or oil quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all cause poor combustion of the air-fuel mixture. Turbocharging issues: Problems with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: If there is a problem with the car's air intake, it may lead to clogged engine pipes, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system malfunctions can also trigger the engine warning light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can all lead to catalytic converter failure. Anti-theft system malfunction: If the car's electronic anti-theft system malfunctions or if the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the engine warning light. Generally, the engine warning light can appear in four scenarios: steady yellow light, flashing yellow light, steady red light, or flashing red light. The severity of the issue increases from steady to flashing and from yellow to red. In order of severity: flashing red > flashing yellow/red > steady red > steady yellow/red. If the engine warning light comes on, follow these steps: First, check if the engine is running normally, whether there is shaking, black smoke, etc. If so, avoid restarting the engine. Note: Do not restart the engine if the red light is on. If the engine can be started, turn it off for 5-10 minutes, then (without pressing the brake) press the start button once or turn the key halfway to the 'ON' position (without pressing the clutch). The car will perform a self-check after powering on. Wait 5-10 seconds and observe whether the warning light on the dashboard turns off. If the warning light remains on, visit a service center as soon as possible. The service center can use a portable diagnostic tool to read the error codes, identify the issue, and perform targeted repairs.

What is the normal tire pressure for the BYD Song Pro?

The normal tire pressure range for the BYD Song Pro is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The specific method to display the tire pressure values on the BYD Song Pro is as follows: there is a mode button on the right side of the steering wheel. Click the down button to scroll through the content, and the third scroll will display the specific tire pressure values. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; multiplies the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually triggers an alarm if below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system still records the previous data, causing the tire pressure monitoring indicator to light up. Simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors tire pressure. If the sensor is damaged during driving, it will trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.

Why Is There Water in a Car Battery?

Car batteries contain water due to prolonged storage or extended use. Here are the detailed explanations: 1. Electrolyte corrosion: The electrolyte inside the battery (paste-like electrolyte) corrodes the battery casing. Once the casing is corroded through, the electrolyte leaks out. 2. Electrolyte dilution: The paste-like electrolyte absorbs moisture from the air, causing it to thin into a watery state. This electrolyte is highly corrosive to metals, so components like the negative terminal spring, positive terminal contact, and even circuit board devices can be damaged. Note: When the battery is fully discharged or left unused for a long time, the dry battery should be promptly removed to prevent component damage.
