Acura 2012 MDX - Manual (Page 483)

If equipped
The blind spot information system
(BSI) is designed to assist you when
you are changing lanes. If the system detects vehicles in
adjacent lanes, it automatically
illuminates the appropriate indicator
to provide assistance when you
change lanes. It is not a substitute for
visual confirmation that it is safe to
change lanes.
Failure to visually confirm that it
is safe to change lanes before
doing so may result in a crash
and serious injury or death.
Do not rely only on the blind
spot information system when
changing lanes.
Always look in your mirrors, to
either side of your vehicle, and
behind you for other vehicles
before changing lanes.
