The number represents the production year of the glass, indicating the last digit of the year. The small black dots denote the production month of the glass. This ultimately gives the production month of the glass. Some glass may also have larger black dots after the production year and month, specifying the week of the month.

On the production date of vehicle glass, there is usually a small marking in the corner, such as numbers with dots. This applies to imported Prado models as well. Having studied cars for many years, I know that numbers typically represent the last one or two digits of the year, while dots indicate the month—for example, "•3" might mean January 2023, but the actual format varies slightly by brand, so it's important to carefully check multiple windows for consistency. Imported car glass may have various certification marks like E or DOT codes—don't get confused; the key is to locate this date code. This helps determine if the vehicle has been in an accident or had glass replaced, especially when buying a used car, which is a good practice. During routine maintenance, I recommend using a flashlight to inspect carefully; the marking might be in the corner of the windshield or side windows, with Prado models being similar to other vehicles. If the marking is worn or illegible, it may be necessary to consult a professional. Overall, this is a small but quite useful skill.

Last time my friend bought a used imported Land Cruiser Prado, he asked me how to check the glass date, so I took him to see it directly. The small code string in the corner of the glass is quite easy to find—the numbers represent the last digit of the year, and the dots indicate the month. For example, '2••' likely means July 2022. We started checking from the windshield and found that all window dates matched the vehicle's manufacturing certificate, indicating no glass replacements, which reassured him a lot. The glass markings on imported Prados usually follow international standards, so it doesn’t affect the inspection. I advised him to check regularly so he can spot issues promptly after an accident. Also, if the glass production date differs too much from the vehicle's age, there might be something fishy—especially since odometer tampering is common in imported cars, so this detail shouldn’t be overlooked. A quick glance while washing the car is simple yet practical.

Checking the glass date on imported Land Cruiser Prado is quite simple: First, locate the small markings in the corner of the window, usually a combination of numbers and dots. The numbers represent the year, and the dots represent the month. For example, "20" might indicate 2020, and dots "••" could mean July. When inspecting, start with the windshield or side windows, as the markings are often found along the edges. As an imported vehicle, the Prado's markings are no different—just ensure the numbers match the vehicle's manufacturing year. If the markings are hard to see, clean the glass or use a flashlight for better visibility. This helps determine if the glass is original, preventing potential issues with used cars. It's also advisable to inspect other parts simultaneously to avoid pitfalls.
