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 16 ft. (5.0 m). 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 do not change when a trailer is towed. If the turn signal is activated and a vehicle is also 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. At speeds greater then 32 km/h (20 mph), SBZA displays may come on when a vehicle you have passed 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 4‑41 for more information. If the SBZA is disabled by the driver, the SBZA mirror displays will not light up during normal driving. How the System Works 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. 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. 3-49
