■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 mirror s or is approaching rapidly from behind into
a blind spot. Do not overly rely on the BSM fu nction. 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.
