The front windshield features a fan-shaped symbol with three curved upward arrows, while the rear windshield has a rectangular symbol with three curved upward lines. The front windshield has an inclined central spray line, whereas the rear windshield has a rectangular central spray line.

The patterns on front and rear windshields can be distinguished mainly by their position and function. The front windshield pattern is usually at the upper edge, like a black border used to block sunlight, and won't appear directly in the driver's line of sight. Some also have grid areas for rain sensors. The rear windshield is noticeably different - patterns cover the entire glass, and you can feel raised heating wires by touch. When activating rear defogger in winter, current passes through those fine wires to heat the glass. Rear windshields often also have radio antenna lines. When parking, observe carefully: rear windshield patterns are denser and more symmetrical overall, while the front has just a simple dark band running across the top - easy to tell apart.
