How to Open the Hood?

Opening the hood involves the following steps: 1. Pull the hood release lever located at the lower left corner of the driver's compartment; 2. Lift the hood and then release the latch. The functions of the hood include: 1. Airflow guidance; 2. Protection for the engine and surrounding pipeline fittings; 3. Assisting driving vision by effectively adjusting the direction of reflected light; 4. Preventing accidents; 5. Isolating heat generated during engine operation. If the hood is stuck and cannot be opened, try these methods: 1. Lubricate the hood latch spring; 2. Use a tool to hook open the hood, or insert a wire from under the vehicle's engine into the hood lock hole to pull it open.

What is the replacement cycle for a car battery?

The replacement cycle for a car battery is approximately 2 to 3 years. Symptoms of a damaged battery include: 1. Insufficient power; 2. Difficulty starting the car; 3. Remote key sometimes malfunctions; 4. Dashboard warning lights turn on; 5. Central control failure; 6. Engine not charging; 7. Car horn not working; 8. Headlights dimming. The functions of a car battery are: 1. Providing power to the starting system, ignition system, and electronic fuel injection system; 2. Acting as a voltage stabilizer for the entire vehicle's electrical system; 3. Assisting in power supply to electrical devices when the generator's output is insufficient. A car battery, also known as a storage battery, can be categorized into: 1. Conventional battery; 2. Dry-charged lead-acid battery; 3. Maintenance-free battery.

How to Use Rearview Mirrors When Driving in an S-Curve?

The method for using rearview mirrors when driving in an S-curve is: 1. When the left front edge of the car aligns with the right line of the S-curve, turn the steering wheel one full turn to the left; 2. From the left rearview mirror, ensure the distance between the car body and the left line is maintained at approximately 30cm; 3. At the curve junction, straighten the steering wheel and then check the right rearview mirror, keeping the car body about 30cm from the right line. Car rearview mirrors are divided into: 1. Left-side rearview mirror; 2. Right-side rearview mirror; 3. Central rearview mirror. Car rearview mirrors are important safety components, and their function is to allow the driver to indirectly see the conditions behind, beside, and below the car, thereby expanding the driver's field of vision.

Which is brighter between LED and xenon headlights?

LED headlights are brighter compared to xenon headlights. The difference between them lies in their working principles: LED headlights directly convert electrical energy into light energy through LED chips; xenon headlights use high-intensity voltage to ignite HID bulbs to produce high-brightness illumination. LED stands for Light Emitting Diode, which is a common light-emitting device that emits light through the recombination of electrons and holes. It is made of compounds containing gallium, arsenic, phosphorus, and nitrogen. Xenon headlights refer to those filled with a mixture of inert gases, including xenon, commonly known as HID xenon lamps. They consist of a lamp head, an electronic ballast, and a wiring control box.

What are the reasons for the engine warning light in Wuling Hongguang S?

The engine warning light in Wuling Hongguang S EV can be triggered by the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or signal interruptions occur, the vehicle's ECU cannot accurately obtain engine data, causing the engine warning light to illuminate. Fuel quality issues: Failure to use the fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light turning on. Poor fuel mixture combustion: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockages can all cause poor fuel mixture combustion. Turbocharger problems: Issues with the intake turbo piping or turbocharger can also trigger the engine warning light. The most common issue is turbocharger damage, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the vehicle's intake system is compromised, it may lead to engine pipe blockages, and in severe cases, the engine warning light may illuminate. A dirty air filter that hasn't been cleaned regularly can cause intake issues. Exhaust problems: Exhaust system faults can also trigger the engine warning light. Causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft and bearing failures, with the catalytic converter being the most common culprit. 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 vehicle's electronic anti-theft system fails or if the anti-theft controller is incompatible with the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, while also triggering the engine warning light. If the engine warning light is on, follow these steps: First, check if the engine is running normally, looking for symptoms like shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the "ON" position (without pressing the clutch). The vehicle will perform a self-check after powering on. Wait 5-10 seconds to see if the warning light turns off. If the warning light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.

Is it necessary to apply underbody armor to a car?

It is necessary to apply underbody armor to a car, and its functions include: 1. Protecting against impacts from flying stones and gravel; 2. Preventing moisture, acid rain, and salt from corroding the metal parts of the vehicle's underbody; 3. Preventing rust and corrosion on the underbody; 4. Ensuring the driving safety of the car owner. The underbody of a car is composed of the transmission system, running gear, steering system, and braking system. It supports and installs the car engine and its various components to form the overall shape of the car, bears the engine power, and ensures normal driving. The functions of the underbody include: 1. Anti-corrosion; 2. Protection against stone impacts; 3. Shock absorption and heat insulation; 4. Noise reduction; 5. Preventing underbody scraping and maintaining stability.
