Deceleration Control
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
For deceleration control the CCM commands the ABS module, which controls the brakes, to automatically apply the brakes to slow the vehicle and maintain a safe distance to the vehicle in front.
Vehicles equipped with a diesel engine, the ACC system uses engine braking to slow the vehicle speed on downward grades, to maintain a safe distance to the vehicle in front.
