Driving and Operating vehicle to help avoid or lessen the severity of crashes when driving in a forward gear. 9-53 Automatic Collision Preparation (ACP) System When driving in a forward gear above 4 km/h (2.5 mph), ACP may help reduce crash damage by applying the brakes. It has a detection range of approximately 60 m (197 ft). This front automatic braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See Forward Collision Alert (FCA) System on page 9-50. . Warning (Continued) Detect a vehicle ahead on winding or hilly roads. Detect a stopped or slow-moving vehicle or other object ahead. Detect a vehicle when weather limits visibility, such as in fog, rain, or snow. In these situations, ACP sensor performance is limited. Intelligent Brake Assist (IBA) IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead. Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released. . . { Warning ACP is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on ACP to brake the vehicle. ACP may not: . { Warning IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs, take your foot off the brake pedal and then apply the brakes as needed. Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes. Brake Preparation When quickly approaching a vehicle ahead, Brake Preparation reduces brake response time by having the brake system prepared for driver braking to occur more rapidly. Respond to stopped vehicles, pedestrians, or animals. (Continued)
