Dodge 2010 Grand Caravan - Owner Manual - Manual (Page 117)

The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function
properly. Do not block the area of the rear fascia where
the radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.). The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning light
located in the outside mirrors.
The BSM system can also be configured to sound an
audible (chime) alert and mute the radio to notify the
driver of objects that have entered the detection zones.
Refer to “Modes Of Operation” for further information.
