Download the firmware (remember to select the corresponding version), which is the update.zip file. Connect your phone to the infotainment screen using a data cable. On your computer, simply right-click the update.zip file and send it to "MX4". Locate the update.zip file, click on "update.zip", and your phone will automatically enter the upgrade interface. The update process will first verify the firmware, and upon successful verification, it will proceed. After a few minutes, you will return to the familiar interface. After entering the system, click on the "System Upgrade" icon on the desktop to view the current version number, indicating a successful upgrade.

What is the principle of tire self-sealing fluid?

The principle of tire self-sealing fluid is to form a thin film on the inner tread area of the tire, sealing punctures in the tread area. Below is an introduction about tires: 1. Introduction: A tire is a circular elastic rubber product mounted on various vehicles or machinery to roll on the ground. 2. History: In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title "Improvement in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. 3. Function: Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. Additionally, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

Is it clockwise or counterclockwise to remove tire bolts?

Removing tire bolts is counterclockwise; clockwise tightens, counterclockwise loosens. Small cars are all removed counterclockwise. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car suspension to mitigate the impact received during driving, ensuring good ride comfort and smooth driving. Tires ensure good adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and maneuverability, while bearing the weight of the car. The important role tires play in automobiles is increasingly being recognized. The first batch of car tire samples appeared in France in 1895, which were single-tube tires made of plain canvas, with tread rubber but no patterns.

Where is the license plate number Meng B from?

Meng B is the license plate number for Baotou City in the Inner Mongolia Autonomous Region. The license plate codes for various regions in Inner Mongolia are as follows: Meng A for Hohhot City, Meng B for Baotou City, Meng C for Wuhai City, Meng D for Chifeng City, Meng E for Hulunbuir City, Meng F for Xing'an League, Meng G for Tongliao City, Meng H for Xilin Gol League, Meng J for Ulanqab City, Meng K for Ordos City, Meng L for Bayannur City, and Meng M for Alxa League. Baotou City is a prefecture-level city in the Inner Mongolia Autonomous Region, designated by the State Council as an important economic center of the region. Located in northern China, at the southern end of the Mongolian Plateau, in central Inner Mongolia, and bordering the Yellow River to the south, Baotou is traversed by the Yin Mountains in its central area. It lies at the heart of the Bohai Rim Economic Zone and the Yellow River Economic Belt, serving as a crucial hub connecting northern and northwestern China, and is a key development area for Inner Mongolia's opening-up policies.

What are the disadvantages of the Aisin 8AT transmission?

The disadvantages of the Aisin 8AT transmission are gearshift jerking and complex structure. The AT transmission, commonly known as the mechanical transmission, uses planetary gears and a torque converter to perform gear shifting operations, replacing the clutch in a manual transmission and helping the driver free the left foot. Its advantages are compact size and durability. The transmission is a very important component in a car. If the transmission responds slowly during daily driving, the overall smoothness of the vehicle will be much worse, and low transmission efficiency will lead to increased fuel consumption. The functions of the transmission are: 1. To change the transmission ratio and expand the range of torque and speed changes of the driving wheels; 2. To enable the car to reverse without changing the rotation direction of the engine.

What is the Difference Between Wheel Balancing and Four-Wheel Alignment?

Wheel balancing and four-wheel alignment differ in their functions: Wheel balancing involves adding counterweights to each wheel to correct the balance of all edges when the wheel is in motion; four-wheel alignment adjusts the data of all four wheels. When a car leaves the factory, the wheels, steering mechanism, and front and rear axles have fixed positions and angles. However, as mileage accumulates and tires wear, these fixed parameters will change. Even minor changes can lead to significant driving risks. Four-wheel alignment ensures the vehicle maintains good driving performance by adjusting the four-wheel parameters.

Why does the tire pressure warning light come on when the tires appear normal?

The reasons for the tire pressure warning light coming on when the tires appear normal: issues with the tire pressure sensor or the detection system's receiving module and wiring. When the tire pressure warning light comes on, do not take it lightly. It is necessary to promptly check the tire condition at a 4S shop. Tire pressure monitoring is a real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to tire leaks and low pressure to ensure driving safety. When tire pressure is too high, it reduces the contact area between the tire and the ground, increasing the pressure the tire bears and affecting traction. When the vehicle passes over bumps or uneven roads, the tire lacks sufficient space to absorb vibrations. Besides affecting driving stability and ride comfort, it also increases the impact on the suspension system, raising the risk of high-temperature tire blowouts.
