WARNING
■
When using the Multi-terrain Monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●
Never rely solely on the Multi-terrain Monitor. As with unequipped vehicles, drive
carefully while directly confirming the safety of your surroundings and the area to the
rear of the vehicle. Take particular care to avoid parked cars and other obstacles.
●
Due to the characteristics of the camera lens, the actual position and distance of peo-
ple and other obstacles will differ from those shown on the Multi-terrain Monitor
screen. Directly confirm the safety of your surroundings before driving.
●
Do not drive while only looking at the screen. When driving, make sure to directly
confirm the safety of your surroundings, such as by visually checking the area and
using the vehicle’s mirrors.
●
In low temperatures, the screen may darken or the images may become faint.
Images of moving objects in particular may distort or disappear from the screen.
Therefore, make sure to drive carefully while directly visually confirming the safety of
your surroundings.
