Introduction to the differences between Michelin 3st and 4st: 1. Different drainage performance. Michelin Primacy 4 features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to 3st, providing excellent drainage that significantly reduces hydroplaning. 2. Different rubber compound. Compared to 3st, Michelin Primacy 4 adopts a new tread design and new rubber compound, improving wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance. Due to the new rubber compound, Michelin 4th generation boasts excellent braking performance, with particularly outstanding wet braking. Official data shows that Michelin Primacy 4 outperforms 3st by a full 2.4m in wet braking distance, enhancing driving safety to some extent.

Is the Car Windshield Tempered?

Car windshields are classified as Class A laminated glass, Class B laminated glass, and zone-tempered glass. Below is relevant information about car windshields: 1. Introduction: Car windshield damage falls under separate glass breakage insurance, which covers compensation when the windshield or side windows break independently. General auto insurance typically requires comprehensive damage; if only the glass is broken, it won't be covered. 2. Causes of spontaneous cracking: Spontaneous cracking of car windshields usually occurs at the edges due to the heating and cooling process during laminated glass manufacturing. This creates internal tensile stress and surface compressive stress. When these forces are in balance, the glass remains stable; otherwise, spontaneous cracking may occur. If a car windshield is exposed to intense sunlight and then suddenly cooled with cold water, the extreme temperature variation may also cause the glass to shatter. If spontaneous cracking occurs, the driver should immediately pull over to the side of the road.

Where is the tire pressure monitoring in the GL8?

GL8's tire pressure monitoring system displays a tire pressure warning indicator on the dashboard. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver in case of tire leakage or low pressure to ensure driving safety. Below is a related introduction: 1. Direct tire pressure monitoring system: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts the driver when the tire pressure is too low or there is a leak. 2. Indirect tire pressure monitoring system: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the rotational speed differences between tires, the system can monitor the tire pressure. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor the pressure.

Is it okay to keep the air conditioning on when the car is not running?

Keeping the air conditioning on when the car is not running is very dangerous. When the car's engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. If the air inside the car cannot circulate, the carbon monoxide emitted by the engine can leak into the car, gradually accumulating and increasing its concentration, leading to poisoning. Here is some information about car air conditioning: 1. Introduction: The car air conditioning device (air-conditioning-device) is referred to as car air conditioning. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates good working conditions for the driver and serves as an important ventilation device for ensuring safe driving.

What are the new regulations for obtaining a driver's license after August 1st?

Below are the relevant new regulations regarding the driver's license test: 1. Relaxation of age restrictions: The new regulations have relaxed the age limit for small cars and small automatic transmission car driver's licenses, removing the upper age limit of 70 years old. Applicants aged 70 and above must undergo tests for memory, judgment, and reaction ability. 2. Lowering of the minimum age for applying for a driver's license: The minimum age for applying for large passenger vehicle and tractor driver's licenses has been adjusted from the original 26 and 24 years old to 22 years old. Legal basis: Article 19 of the 'Road Traffic Safety Law of the People's Republic of China' states that driving a motor vehicle requires obtaining a motor vehicle driver's license in accordance with the law. Applicants for a motor vehicle driver's license must meet the driving license conditions prescribed by the public security department of the State Council; after passing the examination, the traffic management department of the public security organ will issue the corresponding category of motor vehicle driver's license. Holders of foreign motor vehicle driver's licenses who meet the driving license conditions prescribed by the public security department of the State Council and pass the assessment by the traffic management department of the public security organ may be issued a Chinese motor vehicle driver's license.

What is the model number of the oil filter for the Roewe RX5?

The Roewe RX5-1.5T is equipped with SAIC's second-generation SGE series engine. The 20T oil filter is an integrated metal-shell oil filter. The Roewe RX5-2.0T features SAIC's second-generation NLE series engine. The 30T model uses a split-type design, allowing for the replacement of just the filter paper during maintenance. Below is additional information: 1. Functionality: The Roewe RX5 comes with a Tire Pressure Monitoring System (TPMS), which is controlled by the ABS and continuously monitors the speed of each wheel. Under normal driving conditions without brake pedal application, if the ABS detects a discrepancy in the rotational speed of one or more wheels compared to the others, the system calculates the tire pressure change based on the speed difference. When the change exceeds the preset range, the system triggers an alarm, illuminating the TPMS warning light (yellow) on the instrument panel. 2. Exterior Design: The Roewe RX5 adopts the 'Rhythm Design' language, featuring matrix LED headlights composed of 24 LED light sources. The body lines are stylish and dynamic, with a dual-waistline design on the side profile. The roof is equipped with a luggage rack, and the overall vehicle lines are rhythmic and full of tension.

Does the ACC warning light affect normal driving?

It's best not to drive. Below are the related reasons for ACC malfunction: 1. Light is on, but driver experiences no abnormalities: There are two scenarios when the warning light comes on. First, although the light is on, there are no unusual sensations while driving, with acceleration and braking functioning normally. In this case, the vehicle can still be driven normally. This might be due to a temporary sensor malfunction that has since resolved, interference from certain external conditions, or a fault that doesn't affect driving performance but may slightly impact emissions. In such situations, you can continue driving temporarily but should visit a repair shop for inspection as soon as possible. 2. Light is on with abnormal driving sensations: Second, when the warning light comes on accompanied by noticeable abnormalities such as severe shaking or weak acceleration, it's strongly advised not to continue driving. Call for roadside assistance or a tow truck instead. If the repair shop is very nearby, you may cautiously drive there. Since these symptoms indicate a serious malfunction, continued driving could worsen the problem, allow damage to accumulate, or even trigger additional failures. Therefore, continuing to drive is not recommended.
