168 SAFETY
The BSM system sensors operate when the vehicle is in any
forward gear or REVERSE.
BSM Warning Light
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 rear view mirror and extends
approximately 10 ft (3 m) beyond the rear 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 detec-
tion 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 drop outs (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 sec-
onds).
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 prop-
erly. Do not block the area of the rear fascia where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.).
