<b>1.1 Khái quát về hệ thống. </b>

Hệ thớng gạt nước và rửa kính là mợt hệ thống đảm bảo cho ngời lái nhìn được rõ ràng bằng cách gạt nước mưa trên kính trước và kính sau khi trời ma. Hệ thớng có thể làm sạch bụi bẩn trên kính chắn gió phía trước nhờ thiết bị rửa kính. Vì vậy đây là thiết bị cần thiết cho sự an toàn của xe khi chạy. Gần đây mợt sớ kiểu xe có thể thay đổi tốc độ gạt nớc theo tốc độ xe và tự động gạt nớckhi trời mưa.
