When you are approaching a vehicle or object too rapidly or when you are following a vehicle too closely that is ahead of you, FCA may not provide you with enough time to avoid a collision. FCA is not designed to warn the driver of pedestrians or animals. Your complete attention is always required while driving and you should be ready to take action and apply the brakes. For more information, see Defensive Driving on page 316. The Forward Collision Alert (FCA) controls are located on the end of the multifunction lever. 9 (Off): This position turns the system off. R (On): This position turns the system on. To enable FCA, move the Adaptive Cruise Control switch to on. To disable FCA, move the switch to off. 185
