Driving and Operating WARNING (Continued) or vehicle damage. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals. 5.0 m (16 ft). The height of the zone 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 that extend back from the sides of the vehicle do not move further back 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. SBZA Detection Zones The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, 3.5 m (11 ft). This zone starts at each side mirror and goes back approximately 9-33 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 5‑22. If SBZA is disabled by the driver, the SBZA mirror displays will not light up. Left Side Mirror Right Side Mirror Display Display
