242 SAFETY
The BSM system can become blocked if snow, ice, mud,
or other road contaminations accumulate on the rear
fascia/bumper where the radar sensors are located.
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 block-
age 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 sys-
tem will automatically recover and resume function
when the condition clears. To minimize system block-
age, do not block the area of the rear fascia/bumper
where the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.) and keep
it clear of road contaminations.
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
page 244.
Warning Light Location
The BSM system monitors the detection zone from
three different entry points (side, rear, front) while driv-
ing 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.
