When there is a steep upgrade (downgrade) behind the vehicle, the object displayed on the
screen appears farther (downgrade: closer) than the actual distance.
Object at actual position
A: Distance between the vehicle and object displayed on the screen.
B: Actual distance between the vehicle and object.
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.

▼ Picture Quality Adjustment
WARNING
Always adjust the picture quality of the rear view monitor while the vehicle is stopped:
Do not adjust the picture quality of the rear view monitor while driving the vehicle. Adjusting
the picture quality of the rear view monitor such as brightness, contrast, color, and tint while
driving the vehicle is dangerous as it could distract your attention from the vehicle operation
which could lead to an accident.
Picture quality adjustment can be done while the selector lever is in reverse (R).
