Blind Spot Information System (BSI) Alert Indicator
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
While the BSI system is working, the system turns on/blinks* the BSI alert indicator (A) when it detects another vehicle on either side toward the rear.
*: When the driver moves the turn signal lever toward the side with the BSI alert indicator (A) on, the alert indicator blinks to alert the driver.
