AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.
When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand-by mode when
the vehicle is in PARK.
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.7 m). The zone
length starts at the outside mirror and extends approxi-
mately 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 ap-
proximately 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.
