Constant speed control mode:
If the actual vehicle speed is 16 km/h (10 mph) less than the set vehicle speed while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation, as the load on the vehicle may be excessive or the set vehicle speed may be set too high.

Constant speed control mode and vehicle-to-vehicle distance control mode:
If the actual vehicle speed drops below the low speed limit (approximately 50 km/h [30 mph]) while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM when in vehicle-to-vehicle distance control mode and clears the stored vehicle speed in the ECM when in constant speed control mode and cancels the dynamic radar cruise control operation.

Constant speed control mode and vehicle-to-vehicle distance control mode:
If the VSC system operates or a cancel request is received from the 4WD system while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.
