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 260.
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.
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 33 mph (54 km/h).
Fast approaching vehicles will receive an earlier
alert based on relative speed.
Rear Monitoring
Overtaking Traffic
If you pass another vehicle slowly with a relative
speed of less than 15 mph (24 km/h) the warning
light will be illuminated. If the difference in speed
between the two vehicles is greater than 15 mph
