■Differences between the panoramic view display and actual three-dimen-
sional objects
Be aware of the following points when three-dimensional objects higher than
the surface of the road (such as a vehicle bumper) are nearby.
●Panoramic view display
In the panoramic view, the system processes and displays images under the
assumption that the vehicle is on a fl at road surface. Therefore, the position
of three-dimensional objects higher th an the road surface (such as a vehi-
cle bumper) cannot be determined. Even if it seems that a collision will not
occur according to the screen, there may not actually be any extra space
between the vehicle and an obstacle higher than the road surface, resulting
in a collision. In these cases, confir m the safety of your surroundings
directly.
WARNING
■Intuitive parking assist pop-up display
When the intuitive parking assist pop-up disp lay is red, park the vehicle and make sure
to confirm the safety of your surroundings.
Failure to do so may lead to an unexpected accident.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in
a blind spot of the outside rear view mirrors or is approaching rapidly from behind into
a blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is
safe to change lanes, over reliance could lead to an accident resulting in death or seri-
ous injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary.
