Side Blind Zone Alert Your vehicle may have a Side Blind Zone Alert (SBZA) system. Read this entire section before using the system. {CAUTION: The Side Blind Zone Alert (SBZA) system does not detect vehicles outside the side blind zones, which may be rapidly approaching. SBZA is not designed to detect pedestrians, bicyclists, or animals. SBZA is only a lane change aid. If you do not use proper care before changing lanes, vehicle damage, injury, or death could occur. Even with SBZA, always check your vehicle's mirrors, glance over your shoulder, and start your turn signal before changing lanes. The SBZA system is an aid that may help you avoid lane change crashes with vehicles in your side blind spots (zones). When the system detects a vehicle in the side blind zone, amber SBZA displays will light up in your side mirrors. This indicates that it may be unsafe for you 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 start the turn signal. 2-41
