Blind Spot Detection (BSD) is also called blind spot monitoring. This feature uses sensors in the car to detect other vehicles that may be in the Driver's blind spots. An alert light will appear on either wing mirror when a vehicle is in the monitoring zone. If you indicate to change lanes when a vehicle is in the monitoring zone the alert light will flash and an audible alert will sound.
We recommend you always check your blind spot, before changing lanes, even with the BSD systems active.
