forward gear and enters standby mode when the vehicle is
in PARK (P).
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rearview mirror 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 that are outside the
detection zones.
 The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, 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 the
BSM Warning Light remaining illuminated the entire
time the vehicle is in a forward gear
 The Blind Spot Monitoring (BSM) system may experi-
ence 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 taillights, 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 taillights where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.).
The system may also detect blockage if the vehicle is
operated in areas with extremely low radar returns such as
a desert or parallel to a large elevation drop. If blockage is
detected, a "Blind Spot Temporarily Unavailable, Wipe
Rear Corners" message will display in the cluster, both
mirror lights will illuminate, and BSM and RCP alerts will
not occur. This is normal operation. The system will
automatically recover and resume function when the
condition clears.

BSM Radar 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 to sounding an
audible (chime) alert and reducing the radio volume
