Purpose and function of the Mercedes W205 / S205 tailgate window

The offered tailgate window is dedicated to the estate and sedan body styles of the W205/S205 series, where it is responsible for the structural rigidity of the rear body section, proper rear visibility, and the sealing of the luggage compartment. Its placement in the rear zone of the vehicle requires adherence to specific safety parameters, which is why AS2-class glass with controlled light transmission has been used.

The green tint of the glass limits interior heating, reduces glare, and improves the driver's visual comfort, especially when driving in sunny conditions. At the same time, the glass maintains the clarity necessary for safe maneuvering and interaction with the rearview mirror.

AS2 glass construction and the benefits of green tinting

The AS2-type glass used in the tailgate window meets homologation requirements regarding safety and damage resistance. The glass construction is designed to minimize the risk of sharp edges in the event of breakage, which is important for both passengers and the integrity of the bodywork.

• Controlled light transmission – improved driving comfort while maintaining image clarity in the mirror.
• Reduction of interior heating thanks to the green tint of the glass.
• Aesthetic match to the body lines and other windows of the Mercedes C-Class.

The green color of the glass is particularly beneficial in daily use, as it reduces eye fatigue and improves the clarity of the image behind the vehicle, which is important when parking and driving in intense sunlight.

Used condition and installation aspects

The item is offered in used condition, which allows for an economical replacement of a damaged rear window while maintaining the original quality of the manufacturer, Mercedes. For workshops and users, this means the possibility of fitting the glass to the existing tailgate without the need for bodywork modifications.

During installation, it is crucial to use appropriate sealing materials and maintain the correct geometry of the glass seating in the tailgate frame. A correctly installed window ensures:

• tightness of the rear body section,
• structural stability of the tailgate,
• proper operation with the wiper and license plate lighting (if present in the specific vehicle variant).

Application in service and restoration of the Mercedes W205 / S205

The green-tinted tailgate window is often replaced after collisions, mechanical damage, or cracks resulting from body stress. Choosing an original window from the Car Windows category allows you to maintain optical consistency with other glass elements and compliance with factory safety standards.

If you are planning a comprehensive repair or upgrade of the rear body zone in your Mercedes and need other elements from the same group, such as additional side windows, door windows, or other glass components, check the available parts in the Mercedes Car Windows category.

Technical support and selection of used windows

When selecting a used tailgate window, it is worth paying attention to compatibility with the body version, glass type, and color. It is helpful to use the OEM number and interchangeable numbers, which facilitates precise identification of the component in service catalogs and parts selection systems.
