The first button press shows the current follow distance setting on the DIC. The current follow distance setting will be maintained until it is changed. There are six follow distances to choose from.

The faster the vehicle speed the further back your vehicle 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 prefer to travel at a follow distance farther than ACC allows, disengage the system and drive manually. .
