How to Repair Windshield Cracks?

Why does the engine light stay on even though the car is running normally?

There are many reasons why a car's engine warning light may stay on. The engine warning light is also known as the exhaust monitoring light. If the engine warning light is on but doesn't affect driving, it may indicate an intermittent engine fault, which only triggers the warning light without activating the fail-safe mode. The light may turn off after restarting the engine. Here are common reasons for the engine warning light to illuminate: 1. Exhaust emission issues: Problems like poor fuel quality, failed catalytic converter, excessive intake manifold carbon buildup, clogged fuel injectors, faulty oxygen sensors, or occasional engine misfires can trigger the warning light. Among these, poor fuel quality is the most common cause. 2. System malfunctions: The warning light may indicate issues with engine system components such as throttle pedal sensors, throttle position sensors, mass airflow sensors, crankshaft position sensors, or their wiring connections. 3. Transmission system faults: In some vehicles, transmission system problems (internal faults, slippage, overheating) are also indicated through the engine warning light.

What is the transmission of the Mercedes-Benz GLC?

Mercedes-Benz GLC uses a 9-speed automatic manual transmission. The GLC is equipped with a ZF transmission, with the transmission code 9HP. The core structure of this transmission consists of four sets of planetary gears and six shifting elements. Compared to the 8HP, it has one additional shifting element, which controls different combinations of the planetary gears. Here are some related details: 1. The 9-speed automatic manual transmission refers to having nine forward gears. It utilizes nested planetary gears to reduce the length of the transmission body, optimizing the transmission structure to some extent and effectively reducing the overall weight of the transmission. Due to the higher number of gears, it offers advantages in terms of fuel economy. 2. The transmission used in the Mercedes-Benz GLC is also the first longitudinally mounted automatic transmission developed by Mercedes-Benz. This gives the transmission superior performance, faster acceleration, and provides drivers with a more enjoyable driving experience. With lower resistance and higher transmission efficiency, this transmission performs exceptionally well in terms of energy conservation and environmental protection.

Is It Safe to Keep Toilet Water in the Car?

Do not keep toilet water in the car during summer. Toilet water contains 75% alcohol and 5% fragrance, making it highly flammable and easily ignited by open flames. Therefore, after applying toilet water, you must not immediately use open flames, such as lighting mosquito coils, smoking, or using open-flame stoves. Also, avoid direct sunlight exposure. Below are items that should not be kept in the car: 1. Flammable and explosive items: Never store them in the trunk, such as lighters, fireworks, etc. If the car's temperature rises too high or comes into contact with an ignition source, the consequences can be severe. Being caught by traffic police may also result in fines and demerit points; 2. Perfume: Perfume is chemically processed under specific conditions. In high temperatures, these chemical substances can easily volatilize and may even harm the human body. Additionally, direct sunlight can cause explosions; 3. Reading glasses: Reading glasses are convex lenses that can focus light. Prolonged focusing of light can lead to excessively high temperatures at the focal point, potentially damaging the car's plastic interior panels and even causing the vehicle to self-ignite.

What is the transmission model of Dongfeng Fengshen AX7?

Fengshen AX7's manual transmission is the BE4 from Shenlong; the automatic transmission is the 6AT from Aisin. Additionally, the Dongfeng Fengshen AX7 is equipped with either a 2.0L or 2.3L naturally aspirated engine. The maximum output power of the 2.0L naturally aspirated engine is 147 horsepower, while the 2.3L naturally aspirated engine has a maximum output power of 171 horsepower. Below is an introduction to the functions of the transmission: 1. Change the transmission ratio to expand the range of torque and speed changes of the driving wheels, adapting to frequently changing driving conditions, while allowing the engine to operate under favorable conditions (higher power and lower fuel consumption); 2. Enable the car to reverse while keeping the engine's rotation direction unchanged; 3. Utilize neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output in the transmission.

Where is the car music volume control?

Car music players usually have two knobs below the center console screen. The left knob adjusts the volume, while the right knob changes tracks. Some models also feature volume control buttons on the multifunction steering wheel. Below are the usage methods for car music players: Playing music via USB: Turn on the car display screen. Most mid-range and above vehicles have an LCD screen. Locate the button to turn on the display and press it to open the screen. Prepare a USB drive and insert it into the port below the screen. After inserting the USB, the system typically takes about 5 seconds to read it. The downloaded songs from the USB will appear on the center console screen. Click the folder icon in the upper left corner to view all songs in the USB. Bluetooth playback: Some users may encounter no sound when playing music after connecting their phone's Bluetooth to the car's Bluetooth. In this case, first enter the phone's Bluetooth settings interface, where there are two options: phone audio and media audio. After connecting to the car's Bluetooth, both options are enabled by default. You need to turn off the media audio while keeping the phone audio enabled. This ensures that three functions—Bluetooth calls, car music playback (or radio), and phone navigation announcements—do not interfere with each other.

What Causes the Squeaking Sound When Lightly Pressing the Accelerator?

A squeaking or buzzing sound when pressing the accelerator could be caused by the fuel pump or related components. Alternatively, it might indicate a faulty clutch release bearing. It is necessary to check for air leaks in the engine's intake system, ensure the air filter is properly installed, identify the source of the noise, and inspect whether the engine belt is aged, loose, or slipping. Causes and solutions for unusual sounds when pressing the accelerator: 1. Fuel pump motor noise: If the fuel pump motor is worn or contaminated, it may produce abnormal sounds when the accelerator is pressed. In such cases, the fuel pump needs to be replaced. 2. Throttle body noise: Modern throttle bodies are electronically controlled, and the motor is responsible for opening and closing the throttle. If the motor gears are worn, improper meshing can cause noise. Excessive carbon buildup or sludge in the throttle body can also lead to noise. Cleaning the throttle body may help, but if the motor is damaged, the servo motor must be replaced by removing the throttle body. 3. Poor lubrication of the accelerator pedal bearing: Applying grease to the bearing can help lubricate it. 4. Damaged clutch release bearing: This can cause incomplete separation of the clutch disc, resulting in noise. The clutch must be removed to replace the release bearing.
