Driving and Operating 9-51 Assistance Systems for Driving If equipped, when driving the vehicle forward, Forward Collision Alert (FCA), Lane Departure Warning (LDW), Lane Change Alert (LCA), and/or the Active Emergency Braking System can help to avoid a crash or reduce crash damage. FCA detects vehicles within a distance of approximately 60 m (197 ft) and operates at speeds above 40 km/h (25 mph). If the vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to distances of approximately 110 m (360 ft). See Adaptive Cruise Control on page 9-39. FCA can be disabled through vehicle personalization. See the "Auto Collision Preparation" portion of "Collision/Detection Systems" under Vehicle Personalization on page 5-43. Detecting the Vehicle Ahead Forward Collision Alert (FCA) System The FCA system may help to avoid or reduce the harm caused by front-end crashes. FCA provides a flashing red alert on the windshield, and beeps or pulses the Safety Alert Seat when approaching a vehicle directly ahead too quickly. FCA also provides a visual alert if following another vehicle much too closely. { Warning FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. FCA does not warn of pedestrians, animals, signs, guardrails, bridges, construction barrels, or other objects. Be ready to take action and apply the brakes. For more information, see Defensive Driving on page 9-3. FCA warnings will not occur unless the FCA system detects a vehicle ahead. The vehicle-ahead indicator will display green when a vehicle is detected in front. Vehicles may not be detected on curves, highway exit ramps, or hills; or due to poor visibility. FCA will not detect another vehicle ahead until it is completely in the driving lane.
