A tire pressure of 2.2 is not normal and is slightly low. According to international standards and requirements: standard tires should be between 2.4 to 2.5 bar, reinforced tires between 2.8 to 2.9 bar, and the maximum pressure should not exceed 3.5 bar. In winter, it is advisable to increase the tire pressure by about 0.2 bar based on the standard tire pressure, while in summer, the lower limit of the standard tire pressure should be maintained. Hazards of low tire pressure: 1. Increased fuel consumption: The friction coefficient with the road surface increases, leading to higher fuel consumption. 2. Safety risks: It can cause the steering wheel to feel heavy and lead to issues like veering, which are detrimental to driving safety. 3. Abnormal overheating: Increased movement of various parts of the tire can result in excessive rolling, causing abnormal overheating of the tire.

What is the Function of the Anti-Slip Regulation System?

The function of the Anti-Slip Regulation (ASR) system is to control wheel slippage within a certain range during vehicle acceleration, thereby preventing the drive wheels from spinning excessively. Its primary purposes are: 1) to enhance traction, and 2) to maintain driving stability. Further details are provided below: 1. Definition: The Automotive Anti-Slip Regulation System (Acceleration-Slip Regulation or Traction-Control-System), abbreviated as ASR or TCS, is a slip control system developed after ABS. It represents an advanced evolution and crucial supplement to ABS functionality. The ASR system is closely related to the ABS system and is typically used in conjunction with it, forming an active safety system for vehicle operation. 2. Working Principle: On slippery road surfaces, vehicles without ASR are prone to wheel spin during acceleration. Rear-wheel-drive vehicles may experience fishtailing, while front-wheel-drive vehicles may suffer from loss of steering control. With ASR, these phenomena are either prevented or significantly mitigated during acceleration. During cornering, if drive wheel slippage occurs, the entire vehicle may drift to one side. The ASR system helps maintain the correct turning trajectory. In ASR-equipped vehicles, the mechanical linkage between the accelerator pedal and the throttle valve (or diesel injection pump lever) is replaced by an electronic throttle control system. When sensors transmit throttle pedal position and wheel speed signals to the control unit (CPU), the unit generates control voltage signals. Servo motors adjust the throttle position (or diesel pump lever position) accordingly, with position feedback sent back to the control unit for timely brake adjustment.

What are the body dimensions of the Great Wall Pao Off-Road Edition?

The length, width, and height dimensions of the Great Wall Pao Off-Road Edition are 5489mm/2084mm/1920mm, which are official data. The length of the Great Wall Pao Off-Road Edition refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The turbocharged engine of the Great Wall Pao Off-Road Edition has a maximum power of 140kw and a maximum torque of 360 Nm. The maximum power speed of this engine is 4000 to 5500 rpm, and the maximum torque speed is 1800 to 3600 rpm. It is equipped with direct injection technology and uses an aluminum alloy cylinder head and cast iron cylinder block. This engine is matched with an automatic transmission (AT). The country has relevant regulations on vehicle dimensions. According to the national standard "GB1589-89", the total width of the vehicle does not include rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, in the national standard, the significance of vehicle width data is to provide enough space during overtaking, avoiding accidents or situations where road markings are narrower than the vehicle's width due to excessive width. Additionally, the national regulation stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of relevant public roads.

Is the Boyue Pro ZhiLian a mid-range or low-end configuration?

The Boyue Pro ZhiLian version is the low-end configuration of this model. Below is an introduction to the Boyue Pro: Interior: The interior of the Boyue Pro is wrapped in large areas of soft materials, giving it a premium look. Moreover, the car does not pursue so-called 'tech-savvy' features but retains very practical physical buttons, such as air conditioning controls and driving assistance buttons. Due to the electronic gear shift mechanism, there is a large storage space below the electronic gear lever. Powertrain: The Geely Boyue Pro comes in three powertrain versions. The 1.5TD automatic ZhiLian PRO is equipped with a 1.5T turbocharged engine, paired with an Aisin 6AT automatic transmission, delivering a maximum power of 130kW and a peak torque of 255Nm. The 1.5TD DCT intelligent four-wheel-drive PRO is equipped with a 1.5T turbocharged engine featuring a 48V mild hybrid system, paired with a 7-speed dual-clutch transmission, offering a combined maximum power of 140kW and a combined peak torque of 300Nm. This configuration also includes an adaptive four-wheel-drive system. It is worth noting that the above two models are equipped with 3-cylinder engines. The remaining models are equipped with a 1.8T turbocharged engine, paired with a 7-speed dual-clutch transmission, delivering a maximum power of 135kW and a peak torque of 300Nm.

What to Do When the Right Side of Parallel Parking Crosses the Line?

Solutions for crossing the line during parallel parking: 1. Maintain a distance of 30-50 cm from the edge of the parking space. Before starting parallel parking, position your vehicle correctly, keeping the right side of the car 30-50 cm away from the edge line. 2. Control the clutch and speed effectively. Mastering the vehicle's speed is crucial for successful parallel parking. Throughout the process, maintain a slow speed and avoid stopping midway. 3. Avoid crossing the line at these two critical moments: entering and exiting the parking space. Parallel parking requires completing the maneuver in one reverse and one forward movement to enter and exit the side parking space. If the steering wheel is turned too early, it may result in insufficient space in front and excessive space behind, increasing the risk of crossing the edge line. Similarly, turning the wheel too early or too late when exiting the parking space can affect whether the car crosses the line. Therefore, timing is essential.

What does 'scan' mean in Chinese?

scan in Chinese means scanning or searching for radio stations, which stops after finding a station, mostly displayed on the car's electronic screen. When this button is pressed in CD playback mode, the display shows the word 'scan,' and the music will start from the next track of the currently playing song, cycling through each track for a few seconds before moving to the next. When the user hears a track they like and presses the button again, the player will start playing from that track. Other car function introductions: 1. VOL volume adjustment; 2. MUTE mute; 3. MODE mode selection: such as whether the audio source is CD, MP3 from a USB drive, or radio; 4. RDM random playback.

Why is the wiper squeaking?

Wiper squeaking is caused by excessive wear of the wiper or incorrect wiper arm angle, which makes the wiper blade jump on the windshield and produce noise. Solutions: 1. Check if there is dirt or oil stains on the windshield. It is recommended to clean the windshield with a cleaning solution or replace the wiper blade for testing; 2. If the wiper blade is normal, adjust the angle of the wiper arm so that the wiper blade is perpendicular to the windshield plane; 3. Place a cloth on the wiper arm, then use pliers to pinch and break it with force, trying to make the wiper blade perpendicular to the windshield plane.
