Nissan Sentra Owners Manual: Difference between predicted and actual distances

The distance guide line and the vehicle width guide line should be used as a reference only when the vehicle is on a level, paved surface. The distance viewed on the monitor is for reference only and may be different than the actual distance between the vehicle and displayed objects.

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.

For example, the display shows 3 ft (1.0 m) to the place A , but the actual 3 ft (1.0 m) distance on the hill is the place B . 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.

For example, the display shows 3 ft (1.0 m) to the place A , but the actual 3 ft (1.0 m) distance on the hill is the place B . Note that any object on the hill is closer than it appears on the monitor.

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.
