Windshield

Windshield

W220 vehicles have heated windshield with rain and daylight sensors. Optionally windshield can have infrared reflective coating. Facelift windshields have different rain and daylight sensor lens.

Aftermarket windshields for W220 are produced by XYG, Olimpia, Benson, FYG and Pilkington. Pilkington is MB OE producer, therefore it is possible to order windshield directly from Pilkington much cheaper than from MB dealer. The glass will be identical to original MB glass, exept that windshield will be missing the small MB logo on the windshield marking.

Windshield Heating

W220 windshield is equipped with heating element in the windshield area of non-activated windshield wipers. The heating element usually has cutout for the VIN number sticker, since in US it is a federal requirement that the VIN number be visible through the windshield.

Infrared Reflecting Windshield

Vehicles with option code HEAT INSULATING+IR REFLECTG.SAFETY GLASS ALL-ROUND are equipped with infrared reflecting glass including windshield, which reduces the amount of radiated heat entering the interior through the windows.

"IR" mark on the windshield denoting infrared reflecting glass.

Infrared transparent areas

The infrared reflecting glass also prevents the transmission of signals through the glass by in-vehicle electronic devices (e.g. electronic toll collection devices). To allow the use of these devices in the vehicle, two infrared transparent areas (1) and (2) are placed in the windshield.

(1) Mounting location for electronic toll collection devices (infrared transparent) (2) Infrared transparent area (pass-through for electronic signals) (3) 31.5 in (80 cm) (4) 19.0 in (48 cm) (5) 1.75 in (4.5 cm)

Rain Sensor

In facelift vehicles there is no separate daylight sensor, since daylight sensor is integrated in the rain sensor.
