Always check the outside and rearview mirrors, glance over your shoulder, and use the turn signal before changing lanes. When the system detects a vehicle in the side blind zone, amber SBZA displays light up in the side mirrors. This indicates that it may be unsafe to change lanes. Before making a lane change, always check the SBZA display, check the outside and rearview mirrors, look over your shoulder for vehicles and hazards, and use the turn signal.
