Driving and Operating is approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off the ground. Use caution while changing lanes when towing a trailer, as the SBZA detection zones do not change when a trailer is towed. How the System Works The SBZA symbol lights up in the side mirrors when the system detects a vehicle in the side blind zone, indicating it may be unsafe to change lanes. Before making a lane change, check the SBZA display, check all mirrors, glance over your shoulder, and use the turn signals. When the vehicle is started, both outside mirror SBZA displays will briefly come on to indicate the system is operating. When the vehicle is moving forward, the left or right side mirror display will light up if a vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the display will flash to give you extra warning not to change lanes. At speeds greater then 32 km/h (20 mph), SBZA displays may come on when approaching or passing other vehicles. SBZA displays may come on when a passed vehicle remains in or drops back into the detection zone. SBZA can be disabled through the Driver Information Center (DIC). See Driver Information Center (DIC) on page 5‑26. If SBZA is disabled by the driver, the SBZA mirror displays will not light up. 9-51 When the System Does Not Seem To Work Properly Missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced. 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. 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. SBZA does not operate when the SBZA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, slush, or in heavy rainstorms.
