Blind Spot Monitor Mode

WARNING: This page is about a different car, the 2015 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

Unless disabled in the customer programmable features settings received through the Radio Receiver Module (RRM) (also known as the radio or the head unit), the Blind Spot Monitor (BSM) mode is active only when the transmission gear selector is in a position other than Reverse (R ) or Park (P ). The BSM mode is intended to provide a visual alert to the driver when a target vehicle (object of interest) is located in the lane adjacent to and just behind either outside rear view mirror (the detection zone), in the blind spot area where vision of target vehicles may be inhibited by the rear structure of the host vehicle. If a turn signal is activated in the host vehicle in the same direction as that in which the target vehicle is located, a single audible alert tone will also be generated. The audible alerts of the BSM mode are not active unless the turn signal is activated.

The width of the BSM mode detection zone covers one traffic lane over on each side of the host vehicle, approximately 4.0 meters (13 feet). The length of the BSM mode detection zone starts at the outside rear view mirror and extends approximately 4.5 meters (15 feet) rearward from the rear edge of the rear fascia. The BSM mode visual alerts are activated immediately if an object of interest is within the detection zone and meets the warning criteria. However, the BSM system will not activate these alerts if:

The object of interest (target vehicle) comes from the rear of the detection zone and passes the host vehicle at a speed greater that 50 kilometers-per-hour (31 miles-per-hour).
The object of interest (target vehicle) enters the detection zone from the front and remains in the zone for less than 1.5 seconds.
The object of interest (target vehicle) passes through the detection zone with a relative speed greater than 20 kilometers-per-hour (12 miles-per-hour).
The object of interest (target vehicle) passes the host vehicle from the opposite direction.

The BSM mode audible alert may be deactivated if the operator prefers using the customer programmable features settings within the RRM. The BSM mode can be configured for visual and audible alerts, visual alerts only or for the entire BSM system (including Rear Cross Path/RCP mode) to be turned Off.
