Where to Find the Manufacturing Date of Car Tires?

Car tire dates are located on the outer side of the tire. More information about car tire dates is as follows: 1. The car tire date consists of four digits "AABB". The first two digits "AA" represent the week of the year, and the last two digits "BB" represent the year. 2. The 11-digit number and letters immediately following the "DOT" letters on the tire sidewall indicate the identification number or serial number of the tire. The last four digits of the serial number represent the manufacturing date of the tire. 3. The format of the tire manufacturing date code: the first two digits indicate the production week, and the last two digits indicate the production year. For example, if the last four digits of DOT are 0807, it means the tire was produced in the 8th week of 2007, i.e., late February 2007. 4. The manufacturing dates of all four car tires should be consistent and not significantly different from the car's manufacturing time.

Is High or Low Engine Oil Viscosity Better?

There is no definitive answer as to whether high or low engine oil viscosity is better. More information about engine oil viscosity is as follows: 1. Higher oil viscosity leads to higher fuel consumption in the engine. At idle, higher viscosity oil results in lower noise; while driving, higher viscosity oil produces more noise. Lower viscosity oil, on the other hand, has the characteristic of saving fuel. 2. The viscosity of the oil should be selected based on the engine's condition and the ambient temperature. If the internal parts of the engine have small clearances, lower viscosity oil is needed; if the clearances are large, higher viscosity oil is required. 3. New engines with minimal internal part wear and small clearances require lower viscosity oil, while older engines need higher viscosity oil. 4. In summer, when engine temperatures are high, higher viscosity oil is needed to ensure the oil does not become too thin; in winter, lower viscosity oil is required to maintain proper oil flow.

Is a wheel alignment necessary after replacing all tires?

Wheel alignment is necessary after replacing all tires. The specific reasons are as follows: 1. There are certain angles and relative positions between the car tires, steering mechanism, and front and rear axles. After replacing the tires, these angles and positions may deviate. The car may exhibit phenomena such as pulling to one side, reduced steering precision, misaligned steering wheel, and uneven tire wear, necessitating timely wheel alignment. 2. Wheel alignment ensures that the tires maintain proper angles with the car body, reduces wear between the tires and the steering mechanism during driving, ensures tight contact between the tires and the ground, and allows the car to drive stably.

What is Lane Keeping?

Lane keeping system is designed to assist drivers in maintaining the vehicle within a specific lane. Here is a partial introduction to lane keeping: 1. Lane keeping is a type of intelligent driving assistance system: It can control the braking coordination device based on the lane departure warning system, supporting the vehicle to stay in the lane by using a camera to identify the lane markings while driving. 2. The system uses a camera to identify the lane boundaries: When the lane boundaries are detected, the lane keeping system will activate.

How to adjust the rearview mirror of Volkswagen Tiguan?

Volkswagen Tiguan rearview mirror adjustment method is as follows: 1. Central rearview mirror. The rearview mirror should be parallel to the horizon, with the horizon positioned at the center of the mirror (1/2 of the mirror surface) for optimal visibility. The mirror surface should be slightly tilted towards the driver. 2. Left rearview mirror. Since the driver's seat is on the left, the adjustment of the left rearview mirror is particularly important. It is recommended that the car body image occupies 1/4 of the mirror surface, and the horizon occupies 1/2 of the mirror surface. The car body image should not be too much or too little exposed, and the driver should always observe the actual situation of vehicles behind and on both sides while driving. 3. Right rearview mirror. Since the driver's seat is on the left, the right rearview mirror has a large blind spot. It is recommended that the car body image occupies 1/4 of the mirror surface, and the horizon is adjusted to 2/3 of the right rearview mirror.

Can You Shift to Neutral While Driving an Automatic Car?

Automatic cars should not be shifted to neutral while driving. The hazards of shifting to neutral while driving an automatic car are as follows: 1. Reduced braking power: When the car is in neutral and coasting, the connection between the engine and the drive wheels is lost. The car moves forward solely by inertia, and in case of an emergency requiring braking, all braking force must be provided by the brakes alone. 2. Transmission damage: Automatic transmissions require lubrication. When the gear is shifted to N while driving, the oil pump cannot supply oil normally for lubrication, causing the internal components of the transmission to overheat and increasing wear and tear on the transmission.
