Driving and Operating 9-41 Adaptive Cruise Control If equipped with Adaptive Cruise Control (ACC), it allows the driver to select the cruise control set speed and following gap. Read this entire section before using this system. The following gap is the following time between your vehicle and a vehicle detected directly ahead in your path moving in the same direction. If no vehicle is detected in your path, ACC works like regular cruise control. ACC uses camera and radar sensors. See Radio Frequency Statement on page 13-12. If a vehicle is detected in your path, ACC can apply acceleration or limited, moderate braking to maintain the selected following gap. To disengage ACC, apply the brake. If ACC is controlling your vehicle speed when the Traction Control System (TCS) or the StabiliTrak system activates, the ACC may automatically disengage. See Traction Control/Electronic Stability Control on page 9-34. When road conditions allow ACC to be safely used, the ACC can be turned back on. ACC will not engage if the TCS or StabiliTrak is disabled. { Warning Adaptive Cruise Control will not detect or brake for children, pedestrians, animals, or other objects. Do not use Adaptive Cruise Control when: . { Warning ACC has limited braking ability and may not have time to slow the vehicle down enough to avoid a collision with another vehicle you are following. This can occur when vehicles suddenly slow or stop ahead, or enter your lane. Also see "Alerting the Driver" in this section. Complete attention is always required while driving and you should be ready to take action and apply the brakes. See Defensive Driving on page 9-3. On winding and hilly roads or when the sensors are blocked by snow, ice, or dirt. The system may not detect a vehicle ahead. Keep the entire front of the vehicle clean. Visibility is low, such as in fog, rain, or snow conditions. Adaptive Cruise Control performance is limited under these conditions. On slippery roads where fast changes in tire traction can cause excessive wheel slip. . .
