Generally, to help drivers estimate the distance from obstacles, there are three
lines for reference: red, yellow and green. Those three lines are displayed on the
monitor when car is reversing. The green line is 3m from the back of car and the
yellow line is 2m. The open red line is 1m from the back end of car while the
closed red line is 0.4m. Both reference lines on the left and right should leave
0.2m space from the car.

2.1 About guide line
Regular guide line is fixed, but car size and camera mounting position are different
vehicle to vehicle. The fixed guide line is not accurate enough for drivers. There will
be significant difference between regular and fixed guide lines and car's real guide
lines, especially when camera is mounted on the left or right side of car.
