Nissan Maxima Owners Manual: Difference between predicted and actual distances
The displayed guidelines and their locations on the ground are for approximate reference only.
Objects on uphill or downhill surfaces or projecting objects will be actually located at distances different from those displayed in the monitor relative to the guidelines (refer to illustrations). When in doubt, turn around and view the objects as you are backing up, or park and exit the vehicle to view the positioning of objects behind the vehicle.
Backing up on a steep uphill
When backing up the vehicle up a hill, the distance guide lines and the vehicle width guide lines are shown closer than the actual distance.
Note that any object on the hill is further than it appears on the monitor.
Backing up on a steep downhill
When backing up the vehicle down a hill, the distance guide lines and the vehicle width guide lines are shown farther than the actual distance.
Note that any object on the hill is closer than it appears on the monitor.
Backing up near a projecting object
The predicted course lines A do not touch the object in the display. However, the vehicle may hit the object if it projects over the actual backing up course.
Backing up behind a projecting object
The position C is shown farther than the position B in the display. However, the position C is actually at the same distance as the position A .
The vehicle may hit the object when backing up to the position A if the object projects over the actual backing up course.
