If the system detects degraded performance due to
contamination or foreign objects, a message will warn
you of a blocked sensor and the warning indicators in
the side view mirrors will be on. The warning indicators
will remain illuminated until blockage clearing condi-
tions are met. First clear the taillights around the sen-
sors of the blockage. After removing the blockage, the
following procedure can be used to reset the system,
cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the
ignition and driving in traffic, check again for a
blockage.
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 158.
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.
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).
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.
