When the ACC is activated, the millimeter wave radar determines that the ACC is unable to operate normally due to an environmental factors (such as weather or road surface condition and driving or vehicle condition) or other reasons even when the ACC system itself is normal, the millimeter wave radar automatically cancels the activation of the ACC and records the ACC system auto stop control code in it.
When the ACC is automatically canceled, the following message is displayed on the multi information display (MID), and the driver is notified of the cancellation. At this time, the ACC indicator (amber) does not come on.
