for Preparation Click here



Constant speed control mode and vehicle-to-vehicle distance control mode:
If the following conditions are detected while the dynamic radar cruise control system is operating, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
