What Does EV Function Restricted Mean?

EV function restricted generally indicates a failure in the vehicle's high-voltage system. When this issue occurs, it is essential to promptly visit a repair shop or 4S store for professional maintenance to avoid unnecessary trouble during vehicle use. The EV function restriction may be caused by the following reasons: 1: Battery Management System (BMS) module failure. A malfunction in the BMS module can limit battery power output, triggering the "EV function restricted" warning on the dashboard. Technicians use specialized automotive diagnostic tools to read BMS module data and determine if it is faulty. 2: Drive motor failure. A malfunction in the drive motor can also trigger system errors, resulting in the "EV function restricted" warning. Technicians use diagnostic tools to analyze drive motor data and assess whether the motor is faulty. 3: Battery overheating protection. Frequent rapid acceleration during driving can cause the battery to overheat and enter protection mode, limiting power output and displaying the "EV function restricted" warning on the dashboard.

Which Sunglasses to Wear While Driving?

When driving, polarized sunglasses are the recommended choice. Here are some tips for selecting sunglasses: 1. Avoid overly dark lenses: The UV protection capability of sunglasses depends solely on the coating, not the darkness of the lenses. Especially for long-distance drivers, overly dark sunglasses can cause eye fatigue and pose greater risks when transitioning from bright sunlight to suddenly dim areas like tunnels. Dark lenses can delay the transmission of visual signals to the brain, slowing reaction times and increasing accident risks. 2. Choose polarized lenses: Polarized sunglasses are ideal for drivers because they reduce glare and effectively filter out scattered light, providing clear and natural vision. Wearing polarized sunglasses is like having blinds on a window, adjusting incoming light to a uniform direction, making the view indoors appear soft and comfortable. Additionally, polarized sunglasses can diminish harsh light, reduce eye strain, maintain clear vision, and block UV rays. 3. Storage: Properly store your sunglasses to avoid damage. It's best to wrap them in a microfiber cloth and keep them in a glasses case inside the car.

What is the difference between motor vehicles and compact cars?

Small cars and motor vehicles differ in the following ways: 1. Compact cars: Compact cars generally refer to A0-class vehicles within the A-type category. Their wheelbase typically ranges between 2.2 to 2.3 meters, with engine displacements of 1 to 1.3 liters. Compact cars usually have low fuel consumption and a small body size, offering more comfortable and spacious interior space compared to microcars. 2. Motor vehicles: Motor vehicles refer to wheeled vehicles powered or towed by a power device, used for transporting people or goods on roads, or for specialized engineering operations. According to national safety inspection standards for motor vehicles, they can be classified into: large automobiles, compact automobiles, specialized vehicles, special-purpose vehicles, trams, trolleybuses, battery-powered vehicles, three-wheeled motorcycles, two-wheeled motorcycles, mopeds, four-wheeled agricultural transport vehicles, three-wheeled agricultural transport vehicles, and various agricultural tractors.

How to Judge 100 Meters in Subject Three?

Here are the methods to judge 100 meters in Subject Three: 1. Look: Whether it's during the test or driving on your own, always look far ahead while driving. Do not focus on the hood of the car. If you stare at the hood, the car will drift off course. By looking far ahead, you can detect slight deviations and correct the direction in time, making it easier to keep the car moving straight. 2. Find a reference: There is usually a white or yellow line painted on the road that can serve as a reference. To ensure the car is in the center of the lane, align the left corner of the windshield with the line on the road. This helps avoid crossing the line and failing the test. 3. Speed: Speed is the most critical factor during straight-line driving. It is recommended to use third gear for the test because the faster the speed, the easier it is to keep the car straight—provided you hold the steering wheel correctly. Since the straight-line driving test now covers 100 meters, meaning you just need to avoid steering or crossing the line within this distance, a higher speed makes it easier to pass. Using first gear not only slows you down but also makes the car more prone to drifting.

Which is smoother, 75W80 or 75W90 transmission fluid?

Transmission fluid 75W90 has higher viscosity and better stickiness, making it more effective. Generally, 75W-90 is suitable for all seasons in most vehicles. Here are detailed introductions about automotive transmissions: 1. Overview: The transmission is a device that changes the speed ratio and direction of motion, usually located between the clutch and the central drive. It can alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions typically consist of a housing and several gears. 2. Classification: Automatic transmissions have become mainstream internationally, mainly including AT, AMT, CVT, and DCT types. The early transmission systems of AT transmissions were mainly 4AT. AT achieves automatic shifting through an electronically controlled automatic operating system. CVT is a true continuously variable transmission with fewer parts and a smaller size. DCT has two clutches.
