Acura 2012 TL - Manual (Page 526)

The BSI alert indicator starts to blink
as a reminder if you move the turn
signal lever in the direction of the
detected vehicle. Radar sensors, located underneath
each corner of the rear bumper,
detect objects. Do not cover this
area with labels or stickers of any
kind. Always keep this area free of
any kind of dirt every time you get
in the vehicle.
Impacts to the radar sensors or the
area around them can affect
system performance. If an impact
occurs, have the system checked
by your dealer.
