Selecting the Follow Distance (GAP) When ACC detects a slower moving vehicle, it will adjust your vehicle's speed and maintain the follow distance (gap) you select. Use the GAP button on the steering wheel to adjust the follow distance. The distance maintained for a selected follow distance will vary based on vehicle speed. The faster the vehicle speed the further back you will follow. Consider traffic and weather conditions when selecting the follow distance. The range of selectable distances may not be appropriate for all drivers and driving conditions. If you choose to travel at a distance farther than ACC allows, disengage ACC and drive manually. Press the top of the button to increase the distance or the bottom of the button to decrease the distance. The first button press will show you the current follow distance setting on the HUD. Your current follow distance setting will be maintained until you change it. There are six follow distances to choose from. The follow distance selection ranges from near to far (1 second to 2 seconds follow time). A graphic on the HUD indicates the selected follow distance. This picture shows a maximum follow distance. The vehicles will move closer as you select a smaller follow distance. 3-16
