258 SAFETY
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. BSM will alert earlier on
faster-approaching vehicles — up to 15 mph
(24 km/h) difference.
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 204.
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.).
Sensor Location (Left Side Shown)
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning
light located in the outside mirrors. In addition,
when the turn signal is activated during the alert on
the side of the vehicle corresponding to the alert,
an audible (chime) alert can be heard. During this
audible (chime) alert, the radio volume will be
reduced Ú page 261.
BSM Warning Light
The BSM system monitors the detection zone from
three different entry points (Side, Rear, Front)
while driving to see if an alert is necessary. The
BSM system will issue an alert during these types
of zone entries.
