Purpose and Function of the Rear Window

The rear tailgate window in the Mercedes ML W164 is responsible for the driver's safe field of vision, while also contributing to the tailgate's rigid structure. A correctly selected rear window reduces air turbulence behind the vehicle, improves acoustic comfort inside, and allows for proper operation of the wiper and any washer nozzles, if provided in the specific vehicle configuration.

The AS3 designation indicates a specific type of automotive glass used in the automotive industry, adhering to appropriate safety standards. This makes the rear tailgate window resistant to typical operational loads and compatible with factory seals and fittings.

Compatibility and Fit for Mercedes ML W164

The presented window has been specifically designed for the rear of the Mercedes ML W164 generation, ensuring a precise fit to the tailgate's shape. The appropriate edge geometry facilitates installation in original mounting points and cooperation with factory equipment such as trim, seals, and hinges.

Thanks to its original design, the rear window maintains stylistic consistency with the vehicle's other glazing, which is important for both aesthetics and the car's value on the secondary market.

Performance Characteristics and Item Condition

The product comes from the used automotive glass segment, allowing for an economical replacement of damaged glazing while maintaining original specifications. A used rear tailgate window is a good solution for collision repairs, cracks, or mechanical damage incurred during operation.

A correctly selected rear window ensures:

• stable seating in the tailgate frame,
• proper cooperation with seals and fittings,
• maintenance of the factory body line and glazing clarity.

Importance of Correct Vehicle Placement

The placement designated as "rear" means the window is intended exclusively for installation in the tailgate, not in other body areas. Correctly assigning the component to the rear of the vehicle is crucial for safety, sealing, and proper cooperation with the tailgate lifting mechanism and the vehicle's electrical system.

Choosing a window consistent with the rear tailgate design of the Mercedes ML W164 minimizes the risk of stress, leaks, and installation problems, which is particularly important for bodywork and paint repairs and component replacement after a collision.
