What does SEL on a car stand for?

SEL in a car stands for "Select," which is the abbreviation of the English word "Select" on the car dashboard, representing the menu selection confirmation button. Here is an introduction to the car's center console: 1. Introduction: The center console is the control panel located to the right of the steering wheel, in the middle front part of the cockpit. It concentrates most of the car's control buttons except for driving and is the place where comfort and entertainment devices such as car air conditioning and audio are controlled. 2. Function: The design and arrangement of the center console affect the car's comfort and the driver's feeling. Therefore, the center console can also reflect a car's comfort and various functions to a certain extent.

What is API SJ engine oil?

In the engine oil industry, oil grades are classified based on quality levels, with the quality classification following the standards set by API (American Petroleum Institute). The API standard is the most authoritative classification system for engine oil quality in the industry, where quality grades are represented by a combination of two letters. More details about the API quality classification are as follows: 1. The "S" series represents oils for gasoline engines: specifications include SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. 2. The "C" series represents oils for diesel engines: specifications include CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. 3. When both "S" and "C" letters are present: it indicates that the oil is suitable for both gasoline and diesel engines. From "SA" up to "SN," each subsequent letter indicates better performance than the previous one, with letters further in the alphabet representing higher quality grades, making the engine oil more effective. Among international brands, most engine oils are of SF grade or higher.

What does the kinematic viscosity of engine oil mean?

The kinematic viscosity of engine oil commonly referred to is the 40℃ kinematic viscosity, which is the main indicator expressing the lubricating performance of engine oil under low shear speed in a normal temperature environment. It can generally be understood as "the viscosity of engine oil during cold starts at normal temperatures." Generally, the faster the engine oil viscosity approaches or reaches the viscosity during warm-up conditions, the less wear it will cause to the engine. More information about engine oil viscosity is as follows: 1. SAE definition: SAE stands for the "Society of Automotive Engineers" in English. It measures the low-temperature start viscosity, low-temperature pumpability, high-temperature kinematic viscosity, and high-temperature shear viscosity of automotive engine oils, among other values. Based on the measured data, engine oils are classified into several grades, which is the SAE viscosity index of engine oil. 2. Engine oil viscosity: The viscosity labeling of automotive engine oil is mainly divided into three parts: W, the number before W, and the number after W. W is the abbreviation for Winter. The number before W indicates the low-temperature fluidity and the applicable minimum temperature value. The smaller the number, the better the low-temperature fluidity of the engine oil, the better the cold start performance, and the lower the applicable temperature. The numbers before W include 0, 5, 10, 15, and 20. 0 indicates the applicable minimum temperature is -35℃; 5 indicates the applicable minimum temperature is -30℃; 10 is applicable to environments above -25℃, and so on. The number after W refers to the kinematic viscosity of the engine oil in a high-temperature environment of 100℃, including 20, 30, 40, 50, and 60. The larger the number, the higher the viscosity of the engine oil, the better the high-temperature protection performance, and the stronger the sealing capability.

What is the placement distance for a warning triangle on the highway?

On the highway, the warning triangle should be placed at least 150 meters away during the day and at least 250 meters away at night. There are three key points to note when driving on the highway: 1. Entering the highway: Speed should be increased to at least 60 km/h as soon as possible. Vehicles entering from the ramp must accelerate in the acceleration lane and should not obstruct vehicles already in the main lane when merging. They should initially drive in the outer lane. 2. While driving: Vehicles should stay in their designated lanes. Small passenger vehicles should drive in the middle lane, while large buses and trucks should drive in the right lane. 3. Avoid arbitrary lane changes: When changing lanes or overtaking, the turn signal must be activated in advance. At night, drivers should also switch between high and low beams to confirm safety before changing lanes. Overtaking should only be done using adjacent lanes.

What does it mean to drive on the highway shoulder illegally?

Driving on the highway shoulder illegally refers to motor vehicles driving on the outermost right lane of the highway. There are 3 key points to note when driving on the highway: 1. Entering the highway: You should accelerate to over 60 km/h as soon as possible. Vehicles entering from the ramp must speed up in the acceleration lane and must not hinder vehicles already in the main lane when merging. They should drive in the outer lane; 2. During normal driving: Vehicles should drive in their designated lanes. Small passenger vehicles should drive in the middle lane, while large buses and trucks should drive in the right lane; 3. No arbitrary lane changes: When changing lanes or overtaking, you must first turn on your turn signal. At night, you must also switch between high and low beams. Only change lanes or overtake after confirming it is safe, and only use adjacent lanes when overtaking.

What is the reason why the car Bluetooth suddenly cannot be turned on?

There are several reasons why the car Bluetooth cannot be turned on: 1. Car Bluetooth setting failure: Reset the navigation system, restore factory settings, or upgrade the program. 2. The vehicle's Bluetooth is not turned on: This will cause the phone Bluetooth to be unable to detect the vehicle's Bluetooth within range. 3. The phone is too far from the vehicle and cannot connect to Bluetooth: Bluetooth search has a certain distance limitation, and if the distance is too far, the vehicle's Bluetooth cannot be detected. 4. The car Bluetooth is set to be undetectable by Bluetooth devices. Additional information: Below is a brief introduction to car Bluetooth: 1. Overview: Car Bluetooth headsets are designed based on wireless Bluetooth technology for in-vehicle wireless Bluetooth communication. 2. Main function: Connect to the phone via Bluetooth during normal driving for hands-free calls, aiming to free both hands and reduce the risk of traffic accidents.
