Selecting the Follow Distance Gap When a slower moving vehicle is detected ahead within the selected following gap, ACC will adjust the vehicle's speed and attempt to maintain the follow distance gap selected. Press 3 on the steering wheel to adjust the following gap. When pressed, the current gap setting displays briefly on the instrument cluster. Subsequent presses cycle the gap button through three settings: Far, Medium, or Near. Since each gap setting corresponds to a following time (Far, Medium, or Near), the following distance will vary based on vehicle speed. The faster the vehicle speed, the further back your vehicle will follow a vehicle detected ahead. Consider traffic and weather conditions when selecting the following gap. The range of selectable gaps may not be appropriate for all drivers and driving conditions. Changing the gap setting automatically changes the alert timing sensitivity (Far, Medium, or Near) for the Forward Collision Alert (FCA) feature. See Forward Collision Alert (FCA) System on page 9-52. Alerting the Driver Reducing Speed While ACC is at a Set Speed If ACC is already activated, do one of the following: . Use the brake to get to the desired lower speed. Press SET- down and release the accelerator pedal. The vehicle will now cruise at the lower speed. Press and hold SET- down until the desired lower speed is reached, then release it. To decrease the vehicle speed in small increments, briefly press SET−. For each press, the vehicle goes to the next 5 km/h (1 mph) slower mark on the speedometer. . . The speedometer reading can be displayed in either English or metric units. See Instrument Cluster (Base Cluster) on page 5-8 or Instrument Cluster (Uplevel Cluster) on If ACC is engaged, driver action may be required when ACC cannot apply sufficient braking because of approaching a vehicle too rapidly. When this condition occurs, the collision alert will display on the instrument cluster and eight beeps will sound from the front.
