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 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 where the radar sensors
are located with foreign objects (bumper stick-
ers, bicycle racks, etc.).
Sensor Location
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 correspond-
ing to the alert, an audible (chime) alert can be
heard. During this audible (chime) alert, the
radio volume will be reduced. Refer to "Modes
Of Operation" for further information.
Warning Light Location
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.
Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.
Side Monitoring
Entering From The Rear
Vehicles that come up from behind your vehicle
on either side and enter the rear detection zone
with a relative speed of less than 30 mph
(48 km/h).
Rear Monitoring
Overtaking Traffic
If you pass another vehicle slowly with a relative
speed less than 15 mph (24 km/h) and the vehicle
remains in the blind spot for approximately
1.5 seconds, the warning light will be illuminated.
If the difference in speed between the two
vehicles is greater than 15 mph (24 km/h), the
warning light will not illuminate.
