Reverse Parking Distance Warning will operate when the gear is in R (Reverse).
Reverse Parking Distance Warning detects a person, animal or object in the rear when the vehicle’s rearward speed is below 10 km/h (6 mph).
When the vehicle’s rearward speed is below 10 km/h (6 mph), both the front and rear ultrasonic sensors will detect objects. However, the front ultrasonic sensors can detect a person, animal or object when it is within 60 cm (24 in.) from the sensors.

Distance from object	Warning indicator whilst driving backward	Warning sound
30~120 cm (12~48 in.)		Buzzer beeps intermittently
30~60 cm (12~24 in.)		Beeps more frequently
within 30 cm (12 in.)		Beeps continuously

The corresponding indicator will illuminate whenever each ultrasonic sensor detects a person, animal or object in its sensing range. Also an audible warning will sound.
When more than two objects are detected at the same time, the closest one will be warned with an audible warning.
The shape of the indicator in the illustration may differ from the actual vehicle.
