■Panoramic view display range
●In the panoramic view, the system processes and displays images acquired form the 4
cameras under the assumption that the vehicle is on a flat road surface. Therefore, the
display may appear as follows.
• Three-dimensional objects may appear to have fallen over, and be long and thin or bigger than they actually are
• Three-dimensional obje cts at a point higher than the surface of the road may appear
further away than they actually are, or may not appear
• Tall objects may appear to emerge from the image processing seams
●Inconsistencies in th e brightness of images from each camera may occur depending on
lighting conditions.
●The displayed image may not be aligned when the tilt or height of the vehicle changed
due to the number of passengers, cargo we ight or remaining quantity of gasoline.
●The displayed image may not be aligned when the vehicle is in other than “N” (normal)
height mode. (P. 302)
●Images and guide lines may not be properly displayed when the doors are not com-
pletely closed.
●The relative distances between the vehicle ic on and road surface or an obstacle dis-
played in the panoramic view may differ from the actual state.
●If an illuminated license plate is used, it may appear on the screen.
●The black area around the vehicle icon is an area that is not appear in the camera.
Check these areas directly.
■Wide front view display range
●Certain areas at the front of the vehicle ha ve a different sense of distance, and are
masked in black so that they do not appear on the screen.
●There are limits to the range displayed on the screen. Objects at either corner of the
bumper or directly below the bumper are not displayed.
●The perceived distance in images displayed on the screen differs from the actual dis-
tance.
■Images displayed on the screen
Cameras of the Multi-terrain Monitor system use special lenses. The distance of the
image that appears on the screen differs from the actual distance.
●The circled areas shown in the illustration may
be difficult to see, as these are points where
images are combined.
