Blind Spot Information System (BSI) BSI Operation When BSI detects a vehicle in an alert zone, a BSI alert indicator comes on near the corresponding outside rearview mirror. ALERT ZONE A B While your vehicle is moving forward at a speed between 6 mph (10 km/h) and 100 mph (160 km/h), the BSI alert indicator comes on under either of the following conditions: ● The system will not alert you to all vehicles in blind spot zones (such as vehicles you have just passed which you should already be aware of) unless it remains in the alert zone for approximately 2 or more seconds. While the system is on, BSI is active whenever the shift lever is in the D or S position. Driving C A: Approximately 1.6 ft. (0.5m) B: Approximately 10 ft. (3m) C: Approximately 10 ft. (3m) BSI is designed to detect vehicles in specified alert zones adjacent to your vehicle, particularly in harder to see areas commonly known as ''blind spots.'' Another vehicle overtakes you, entering the alert zone from behind, at a speed that differs from your vehicle's speed by no more than 31 mph (50 km/h). You pass a vehicle at a speed that differs from that vehicle's speed by no more than 12 mph (20 km/h). The indicator comes on approximately 2 seconds after the vehicle enters the alert zone. ● CONTINUED 477
