Blind Spot Information System (BSI) Important Precautions Like all assistance systems, BSI has limitations. Over-reliance on BSI may result in a collision. Always look in your mirrors, to either side of your vehicle, and behind you for other vehicles before changing lanes. The system should be turned off when towing a trailer. Due to the added mass and resulting changes in radar coverage, the system cannot operate as intended, and detection of the trailer itself by the radar sensors may cause the BSI alert indicators to illuminate. Limitations The BSI alert indicators may not illuminate under the following circumstances: ● The speed difference between your vehicle and a vehicle approaching from behind is greater than 31 mph (50 km/h). A vehicle is parked in a side lane. The speed difference between your vehicle and the vehicle you are passing is greater than 6 mph (10 km/h). An object not detected by the radar sensors approaches or passes your vehicle. ● ● ● 474 2011 MDX
