Assistance in detecting vehicles behind when changing lanes

The Blind Spot Monitor is a system that uses rear side radar sensors installed on
the inner side of the rear bumper on the left and right side to assist the driver in
confirming safety when changing lanes.

WARNING

■

Cautions regarding the use of the system

The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor 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 Blind Spot Monitor. As the function cannot
judge if it is safe to change lanes, over reliance could lead to an accident resulting in
death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual
confirmation of safety is necessary.

Supporting safe exit by detecting detectable objects at the rear of
the vehicle by outputting sounds, displaying screens as a warning or
cancelling opening of the doors

The Safe exit assist (with door opening control) is a system that uses radar sensors
installed on the inner side of the rear bumper to help occupants judge if an
approaching vehicle or bicycle may collide with a door when opening it or cancel
opening of a door, to reduce the possibility of a collision.

WARNING

■

Cautions regarding the use of the system

●

The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.

●

Safe exit assist is a supplementary system that, when the vehicle is stopped, informs
occupants of the existence of approaching vehicles and bicycles. As this system alone
cannot used to judge safety, over-reliance on this system may lead to an accident
resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary.
