W220 vehicles have windshield

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 numbet 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.
