The SBZA detection zones do not change if the vehicle is towing a trailer. So be extra careful when changing lanes while towing a trailer. How the System Works I (SBZA): To turn SBZA on or off, press the CONFIG hard key located on the navigation radio, then press I . See "Configure Menu" in the index of the Navigation System manual. The symbol will be highlighted when the feature is active. If SBZA is disabled by the driver, the SBZA mirror displays will not light up. When the System Does Not Seem To Work Properly Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced due to an occasional missed alert. The number of missed alerts will increase with increased rainfall or road spray. If the SBZA displays do not light up when the system is on and vehicles are in the blind zone, the system may need service. Take the vehicle to your dealer/retailer. SBZA is designed to ignore stationary objects; however, the system may occasionally light up due to guard rails, signs, trees, shrubs, and other stationary objects. This is normal system operation, the vehicle does not need service. Left Side Mirror Display Right Side Mirror Display When the vehicle is started, both outside mirror displays will briefly come on to indicate that the system is operating. When the vehicle is moving forward, the left or right side mirror SBZA display will light up if a vehicle is detected in that blind zone. When the turn signal is used and a vehicle has been detected on the same side, the SBZA display will flash to give you extra warning not to change lanes. SBZA displays do not come on while the vehicle is approaching or passing other vehicles. 3-45
