From the official Press Release:

In Japan, the Around View Monitor will debut in the new Elgrand, scheduled for introduction at the end of October. The technology will also be offered to the U.S. market on the all new Infiniti EX35 scheduled for launch this December 2007.

The Around View Monitor system sythesises a bird’s eye image of the vehicle and its surroundings from four ultrawide-angle (180-degree) high-resolution cameras mounted on the front, sides and rear of the vehicle.

It is particularly helpful when parking, enabling the driver to steer easily and precisely into a parking space.

The screen displays the view from above on the left, and a front or rear view on the right.

The front and rear views alternate according to the gear shift. This allows the driver a comprehensive view of the vehicle and its surrounding environment from all angles.

The left side-view is offered with the rear view, allowing the driver to more easily observe both the rear and left-front when attempting to parallel-park.

The driver has the option to choose between the top view and the left side-view.

The camera-enabled sensors mounted on all four corners of the vehicle depict the distance to an obstacle in easy-to-understand coloured graphics, and help warn the driver via a “beeping” alert the closer the vehicle approaches a fixed obstacle.
