DYNAMIC RADAR CRUISE CONTROL SYSTEM FAIL-SAFE CHART

  1. Tip:

    If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.
