  • Always look around your vehicle to make sure there are no pedestrians or objects before parking.
  • The performance of Reverse Parking Collision-Avoidance Assist may differ under certain conditions. If your vehicle speed is greater than 2 mph (4 km/h), Reverse Parking Collision- Avoidance Assist provides collision avoidance assist only when pedestrians are detected.
  • Some objects may not be detected by the rear ultrasonic sensors due to the object's distance, size, or material.
