What to Do When Feeling the Car Swaying Left and Right While Driving?

What does the letter H on a tire mean?

The letter H on a tire represents the speed rating of the tire. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. Here is some relevant information about tires: Tires are circular elastic rubber products installed on various vehicles or machinery, mounted on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Below are the steps for replacing a tire: 1. Park the vehicle, turn off the engine, and apply the handbrake; 2. Place heavy objects in front of and behind the wheel to prevent slipping, and set up a triangular warning sign behind the vehicle; 3. Use a wrench to loosen the lug nuts of the tire to be replaced in a diagonal pattern; 4. Position the jack on the side of the vehicle where the tire needs to be replaced and lift the vehicle to a certain height; 5. Remove the lug nuts and take off the tire; 6. Install the spare tire or new tire, tightening the lug nuts in a diagonal pattern; 7. Lower the vehicle by releasing the jack and ensure that all nuts and bolts are securely tightened.

What to Do When Accumulating 12 Points on the Driving License?

If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security authority shall detain their motor vehicle driving license. The driver must, within 15 days, attend a seven-day study session on road traffic safety laws, regulations, and related knowledge at the traffic management department where the driving license was issued. The classifications of driving licenses are as follows: 1. Introduction One: A1 for large buses and A3, B1, B2; A2 for tractors and B1, B2.M; A3 for city buses and C1; B1 for medium-sized buses and C1.M; B2 for large trucks and C1.M. 2. Introduction Two: C1 for small cars and C2, C3; C2 for small automatic transmission cars; C3 for low-speed trucks and C4; C4 for three-wheeled cars. 3. Introduction Three: D for ordinary three-wheeled motorcycles and E; E for ordinary two-wheeled motorcycles and F; F for light motorcycles; M for wheeled self-propelled machinery; N for trolleybuses; P for trams.

Why does Mercedes CarPlay frequently disconnect?

Reasons why Mercedes CarPlay frequently disconnects: Data cable connection issues: This is a common problem encountered by many car owners. Due to the data transmission function of the cable, prolonged use can lead to failure, resulting in the cable only being able to charge but not transmit data. It is necessary to purchase a new data cable, preferably an original one or an MFI-certified data cable for connection. USB port issues: Frequent plugging and unplugging of the data cable can cause the USB port to become loose, have poor contact, or become damaged. It is necessary to check if these are the causes. If not, it is also important to check if the USB port current is too low. If the current is too low, it may result in the connection being established briefly before disconnecting, and re-plugging may temporarily restore the connection. If this is the case, it is necessary to increase the USB port current or use a one-male-two-female data cable, with one end connected to a power bank for use.

Which is better, multi-point fuel injection or direct injection? What are the differences?

Direct injection is better. The differences between multi-point fuel injection and direct injection are as follows: 1. Differences in maintenance. Direct injection diesel engines have lower daily maintenance costs and generate higher torque during operation, providing strong power. However, the drawbacks are also evident. Due to the generally low quality of domestic fuel, abnormal diesel supply can easily lead to increased carbon deposits in the cylinders, reduced power, lower engine speed, and difficulties in ignition and starting. In contrast, electronically controlled fuel injection diesel engines can achieve good compatibility with hydraulic systems. The downside is that they require higher fuel quality, and the maintenance costs are relatively higher compared to direct injection engines. Additionally, severely damaged components often require manufacturer repairs, making it difficult for individuals or small workshops to fix them. 2. Differences in energy efficiency and environmental protection. Direct injection engines have strong adaptability to fuel quality, but the fuel cannot be completely burned, resulting in higher fuel consumption and being less environmentally friendly. Electronically controlled fuel injection engines have relatively higher requirements for fuel quality, but they ensure complete fuel combustion, offering better fuel efficiency and environmental protection.

What to Do If Your Driver's License Has Been Expired for Over a Year Without Renewal?

If your driver's license has been expired for over a year, it can still be renewed as long as it hasn't exceeded three years. However, you will need to pass the subject one exam before you can "normally" renew your license. License renewal and inspection must meet the following conditions: Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses must have no demerit points in the current scoring cycle, or holders of other permitted driving licenses must have less than 12 demerit points in the current scoring cycle. Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses who have demerit points in a scoring cycle, or holders of other permitted driving licenses who have been involved in a traffic accident causing death and bear equal or greater responsibility without having their driver's license revoked, must have completed the inspection education. The applicant must have no pending road traffic safety violations or traffic accidents. The applicant's physical condition must meet the driving permit requirements. The motor vehicle driver's license must not be under circumstances of being legally seized, detained, temporarily suspended, revoked, canceled, or annulled.

Where is the drain plug for the automatic transmission fluid of the Haval H2 located?

The drain plug for the automatic transmission of the Haval H2 is located underneath the transmission housing, while the bolt on top is the filling hole. The functions of transmission fluid are as follows: Reduce friction and wear, control clutch friction and synchronizer performance. Bear loads (low speed with high torque, vibration loads), dissipate heat, reduce vibration and noise, and remove contaminants from gear meshing areas (cleaning function). Prevent corrosion, pitting, and surface metal tearing, isolate metal surfaces to prevent direct contact between metal parts. The methods for changing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: Dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.
