The distance guidelines represents the distance to
the road surface, so you cannot judge the distance
to an object based on these marks.

In the display, according to the distance
guidelines, the truck seems to be parked
about 39" (1 m) away (at position 8).1n fact,
however, if you reversed to position A, you
would collide with the truck.
In the display, positions A, 8 and C seem to
be located in order of proximity. However,
position A and Care the same distance, and
8 is further away than positions A and C.
• The car width extension mark represents the distance
to the road surface, so when an object on the road
surface is displayed on the screen, the mark does not
represent the actual distance to the object.
• In the following conditions, screen visibility may be
impaired. This is not a malfunction.
- When it is dark (at night, etc.).
- When the temperature around the camera lens is
high or low.
- When water drops adhere to the camera, or when
the humidity is high (such as rainy weather, etc.).
- When foreign bodies (such as mud, etc.) adhere to
the camera or its peripheral area.
- When sunlight or headlights directly strike the
camera lens.

Error Error
The distance guidelines represents the
distance to a flat road surface. Therefore in
the case of an upward slope behind the car,
the distance guidelines appear further from
the vehicle than their actual position. For
example, if there is an object on the upward
slope, it may appear further away than its
actual position.
Also, an error may occur between the
guidance and the actual path of the car on
the road surface.
