ONITORING
(BSM)
BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.
Rear Detection Zones
When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear.
The BSM detection zone covers approximately one
lane in width on both sides of the vehicle 12 ft
(3.8 m). The zone length starts at the side of the
vehicle, near the B-pillar, and extends
approximately 10 ft (3 m) beyond the rear fascia/
bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle
when the vehicle speed reaches approximately
6 mph (10 km/h) or higher and will alert the driver
of vehicles in these areas.
NOTE:

The BSM system DOES NOT alert the driver
about rapidly approaching vehicles (greater
then 15 mph) that are outside the detection
zones.

The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There -
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object (i.e.,
bicycle, sports equipment) extends beyond the
side of your vehicle, this may result in random
false detections on the trailer, and false chimes
when the turn signal is used
Ú
page 193.

The BSM system may experience dropouts
(blinking on and off) of the side mirror warning
indicator lamps when a motorcycle or any small
object remains at the side of the vehicle for
extended periods of time (more than a couple of
seconds).
The area on the rear fascia/bumper 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/bumper where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).
