Some variance occurs between the actual road and the displayed road. Such variance in distance perspective could lead to an accident. Note the following conditions that may cause a variance in distance perspective.
When the vehicle is tilted due to the weight of passengers and load
When the vehicle rear is lowered, the object displayed on the screen appears farther than the actual distance.

When there is a steep grade behind the vehicle
When there is a steep upgrade (downgrade) behind the vehicle, the object displayed on the screen appears farther (downgrade: closer) than the actual distance.

Three-dimensional object on vehicle rear
Because the distance guide lines are displayed based on a flat surface, the distance to the three-dimensional object displayed on the screen is different from the actual distance.
