Turns And Bends
In turns or bends, ACC may detect a vehicle ahead too late or too early. This may cause your vehicle to brake late or unexpectedly. Give extra attention in curves and be ready to apply the brakes if necessary. Be sure to select an appropriate speed while driving in curves.

ACC may occasionally provide braking and/or a driver alert that you consider unnecessary. This may be the system’s response to signs, guardrails, and other stationary objects in a curve. This may also occur at the base of steep hills. This is normal operation and your vehicle does not require service.
