Feature Limitations
LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when changing lanes may result in injury, death, or vehicle damage. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals.
- Lane Change Alert displays may not come on when passing a vehicle quickly, for a stopped vehicle, or when towing a trailer.
- Lane Change Alert may alert to objects attached to the vehicle, such as a trailer, bicycle, or object extending out to either side of the vehicle. Attached objects may also interfere with the detection of vehicles.
- Lane Change Alert may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp curves.
- The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects.
- Lane Change Alert may not operate when the B218L Side Object Sensor Module - Left or B218R Side Object Sensor Module - Right sensors in the corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms.
