If the Rear Park Assist System is enabled at this shifter position, the system will be active until the vehicle speed is increased to approximately 11.2 miles/hr (18 km/h) or above. The system will be active again if the vehicle speed is decreased to speeds less than approximately 9.94 miles/hr (16 km/h).

The monitored area seems oval in shape. The sensors can detect obstacles from approximately 11.8 inches (30 cm) up to 59 inches (150 cm) from the rear fascia in the horizontal direction, depending on the location and orientation of the obstacle and the type of obstacle.
