There is a code located at the bottom left or right corner of the car window glass. The production date of the glass can be found in the last or second last row, which consists of a number and several small black dots. Below are some methods to check a car's production date: 1. Check the car's nameplate: The nameplate contains various information, including the engine model, engine displacement, and the car's production date. 2. Inspect the front windshield: The production date of the glass is usually marked in the corner of the front windshield. Unless the glass has been replaced due to damage, this date generally does not differ significantly from the car's overall production date. 3. Look at the VIN (Vehicle Identification Number): Also located below the front windshield, the VIN is a 17-digit code commonly referred to as the chassis number. It is broadly divided into three parts: the World Manufacturer Identifier (positions 1-3), the Vehicle Descriptor Section (positions 4-9), and the Vehicle Identifier Section (positions 10-17). The most important digit to note is the 10th one, which indicates the manufacturing year. If this year is significantly older than the current year, the car may be a long-term stock vehicle. 4. Examine the engine: Normally, the engine compartment should be relatively clean. When starting, the engine should run quickly and smoothly without shaking. You should not feel any vibration when touching the engine, and the sound of the engine running should be barely audible from inside the car.

How to Use the Vehicle Regeneration Switch?

When the vehicle is driving normally, the two switches on the center console—the self-resetting switch and the regeneration prohibition switch—should remain in their original positions and not be pressed. When the high-temperature emission light comes on, it indicates that the engine's active regeneration has started to take effect, and only then should the self-resetting switch button be pressed. If road conditions are poor and the vehicle's own driving regeneration function cannot fully consume the particulate matter in the DPF, parked regeneration will be required.

What to do if water gets into the headlights of a Sagitar and causes fogging?

The presence of fog inside the headlights is mostly due to a significant temperature difference between the interior of the headlight and the environment. This phenomenon may also occur after the vehicle has driven through water, been washed, or had the engine compartment cleaned, if the accumulated water is not thoroughly dried or drained. However, it generally doesn't require attention and can be ignored, as the fog will usually dissipate on its own after some time of use.

How to Remove Paint from Car Glass?

Use a cloth dipped in industrial alcohol to wipe it. Generally, the paint can be removed by wiping with alcohol. If it cannot be cleaned completely, you can dip a little gasoline and wipe again. However, do not spray it directly on the glass. It is recommended to spray the cleaning agent on a towel and then wipe the glass to remove the paint. If the paint area is large, it is recommended to go to a professional car beauty shop. Professional auto repair personnel will perform detailed scrubbing and removal for this situation.
