Baojun e100 brake failure displaying EVP is due to a damaged brake booster pump. Below is the relevant introduction of the Baojun e100: 1. Appearance: The front face of the Baojun E100 features a perforated grille with smooth lines. The A-pillars are blackened, combined with a two-tone body design, creating a visual effect of a floating roof. 2. Interior: The interior of the Baojun E100 adopts an encircling design, with multi-directional adjustable seats. The multifunctional steering wheel and LCD combination instrument panel can achieve most functions. Additionally, the Baojun E100 has a 190L capacity trunk and up to ten storage spaces inside the car. 3. Configuration: The Baojun E100 comes standard with lens headlights, front fog lights, LED turn signals, a multifunctional steering wheel, a 7-inch instrument panel, one-touch window lowering, rear parking sensors, 2 USB ports, onboard 4G Wi-Fi, onboard Bluetooth, App car connectivity, and four-wheel disc brakes. The Zhi Xiang version adds features such as electric adjustment for the exterior rearview mirrors, keyless entry/one-touch start, electronic parking brake, four-way seat adjustment, vehicle stability system, front passenger ISOFIX interface, and 5 USB ports.

Don't panic when encountering a Baojun E100 brake failure with the EVP light on—it's a warning about the electronic vacuum pump issue. Unlike fuel-powered vehicles, our electric cars rely entirely on this electric vacuum pump for brake assistance. I've previously serviced several similar cases in the workshop and found three common possibilities: first, the vacuum pump itself is faulty, with a seized or burnt motor; second, there's air leakage in the vacuum tube, especially at the connecting rubber tubes that may have aged and cracked; third, it could be a sensor false alarm or wiring short circuit. Another easily overlooked point: unstable voltage from the small battery can also trigger false alarms. It's recommended to pull over immediately and check, trying to restart the vehicle to see if the light disappears. If the fault light remains on, never force the car to drive—the brake assistance will weaken, and even steering will become difficult.

Should You Use a Sunshade Mat on the Car Dashboard in Summer?

You do not need to place a sunshade mat on the car dashboard in summer. Reasons not to use a sunshade mat: It covers the passenger airbag, which can block the airbag from deploying—a major safety issue. Since many car dashboards are made of hard plastic, they can easily reflect sunlight onto the windshield in summer, affecting the driver's visibility. It hinders heat dissipation. The dashboard is a high-temperature area that requires proper cooling. Adding a mat in summer traps heat, directly impacting heat dissipation. Vehicle materials and production undergo strict testing, so sun exposure does not affect the interior. The mat tends to accumulate dust. When air blows toward the dashboard, dust from the mat can flow back and blow directly onto the faces of front-seat passengers. A clean and simple dashboard is preferable. Purpose of a sunshade mat: A car dashboard sunshade mat, also known as a sun protection mat, is designed to prevent reflections of the interior scene on the windshield, ensuring driving safety and protecting the dashboard from accelerated aging due to sun exposure.

What is an overhead crane composed of?

An overhead crane is composed of the bridge, trolley, and electrical components. Definition of an overhead crane: Overhead crane: Also known as a bridge crane. It is a type of bridge crane where the bridge runs on elevated tracks. Specific operations of an overhead crane: Before starting work, it is mandatory to wear appropriate personal protective equipment. Only personnel with professional qualifications should operate lifting equipment, and others are not allowed to operate it casually. Ensure the grounding wire is intact. Before starting, check if the lifting buttons are functioning properly and if all electrical, mechanical, and interlocking devices are in good condition. Conduct a no-load operation before lifting to check for any abnormalities. The weight of the lifted items must not exceed the rated capacity. Before lifting heavy objects, ensure the slings are securely fastened and not prone to slipping. When lifting, first raise the object slightly off the ground to ensure it can be lifted safely and avoid dropping. Avoid diagonal or off-center pulling. Ensure no personnel pass beneath the lifted load to prevent hazards. Regularly inspect the slings to prevent breakage.

How to Deal with Water Leakage Under the Passenger Seat?

The method to handle water leakage under the passenger seat is to use a wire to unclog the drainage hole. The area under the passenger seat contains the air conditioning drainage hole. If it gets blocked, the water from the air conditioning system cannot drain out and will flow back into the cabin, causing water to seep out onto the floor of the passenger side. This issue should be addressed promptly to prevent the carpet from getting wet and developing mold. Common areas in a car prone to water leakage include: 1. Sunroof: Leakage from the sunroof can occur due to two main reasons. One is an issue with the sunroof drainage outlet, often caused by blockages from dust, leaves, or twigs, preventing proper drainage and leading to water seepage. This is a common problem with sunroof leaks. The other reason is the aging of the sealing strip. 2. Trunk: Water leakage into the trunk happens when rainwater flows through the tail light area into the trunk, usually due to aging of the trunk seal. Replacing the seal strip can resolve this issue.

What is the maintenance interval for the Lexus UX?

Lexus UX maintenance interval is every 5,000 kilometers or 6 months. Below are detailed introductions about the Lexus UX: 1. All models come standard with 18-inch alloy wheels, automatic LED headlights, and the world's first wing-type spoiler design at both ends of the taillights, which can effectively suppress airflow disturbance on the rear surface of the vehicle, providing better stability during turns and sidewind driving. 2. As a new model in the Lexus UX series, the 2019 UX directly adopts the universal chassis used by most of Toyota's recent new cars, including the Toyota C-HR, Corolla, and Lexus ES series. The UX series is positioned in the Lexus product line as an entry-level SUV one level below the NX (it can also be considered as a replacement for the CT series). 3. Similar to other competitors in its class, the UX200 is equipped with a 2.0L four-cylinder engine without turbocharging technology. This engine has performed excellently in the 2020 Corolla (North American version). Lexus claims a 0-100 km/h acceleration time of 8.9 seconds.

How to Reset the Volkswagen Tire Pressure Warning Light?

Methods to reset the Volkswagen tire pressure warning light: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, leading to a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the purpose of monitoring tire pressure is achieved. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system.
