Buick Regal: Adaptive Cruise Control
If equipped with Adaptive Cruise Control (ACC), it allows for selecting the cruise control set speed and following gap. Read this entire section before using this system.
ACC uses a radar sensor to detect other vehicles. The following gap is the following time (or distance) 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.
If a vehicle is detected in your path, ACC can speed up the vehicle or apply limited, moderate braking to maintain the selected following gap.
To disengage ACC, apply the brake.
If the Traction Control System (TCS) or StabiliTrak electronic stability control system activates while ACC is engaged, ACC may automatically disengage. When road conditions allow ACC to be safely used, ACC can be turned back on. ACC will not engage if the TCS or StabiliTrak electronic stability control system is disabled.
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.
Warning: ACC will not detect or brake for children, pedestrians, animals, or other objects.
Do not use ACC when:
- 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. ACC performance is limited under these conditions.
- On slippery roads where fast changes in tire traction can cause excessive wheel slip.

If ACC is engaged, driver action
may be required when ACC cannot

approaching a vehicle too rapidly.

On curves, ACC may not detect a
