Ultrasonic Parking Assist
If available, Ultrasonic Front and Rear Parking Assist (UFRPA) uses sensors on the front and rear bumpers to detect objects while parking the vehicle. It operates at speeds less than 8 km/h (5 mph).
UFRPA uses audio beeps to provide distance and system information.
Keep the sensors on the vehicle's front and rear bumpers clean to ensure proper operation.
See Ultrasonic Parking Assist for more information.
