Variance Between Actual Road Conditions and Displayed Image
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.
