• Any non-factory equipment or accessory is installed on the rear of your vehicle.
• Your vehicle has been damaged due to an accident or other causes.
• Bumper height or rear ultrasonic sensor installation locations have been modified.
• Rear view camera or rear ultrasonic sensor(s) is damaged.
• Rear view camera or rear ultrasonic sensor(s) is covered or blocked with snow, water, or dirt.
• The surrounding is very bright or dark.
• The weather is very hot or cold.
• The wind speed is either greater than 12 mph (20 km/h) or blowing perpendicular to the rear bumper.

• Any non-factory equipment or accessory is installed on the rear of your vehicle.
• Your vehicle has been damaged due to an accident or other causes.
• Bumper height or rear ultrasonic sensor installation locations have been modified.
• Your vehicle height is lower or higher than normal due to heavy loads, abnormal tire pressure, etc.
• Rear view camera or rear ultrasonic sensor(s) is covered or blocked with snow, water, or dirt.
• The pattern on the road is mistaken for a pedestrian.
• There are shadows or light reflecting on the ground.
• Objects generating excessive noise, such as vehicle horns, loud motorcycle engines, or truck air brakes, are near your vehicle.
• Your vehicle is backing toward a narrow passage or parking space.
• Your vehicle is backing towards an uneven road surface, such as unpaved road, gravel, bump, gradient, etc.
• A trailer or hitch mounted carrier is installed on the rear of your vehicle.

• Pedestrians or objects are near the path of your vehicle.
• The pedestrian or object is moving very quickly.
• You accelerate your vehicle or drive in circles.

WARNING

Reverse Parking Collision-Avoidance Assist may not operate in all situations and cannot avoid all collisions. To prevent serious injury or death:

• Always pay attention to road and traffic conditions while driving. Brake as needed to avoid collisions. Do not solely rely on Reverse Parking Collision-Avoidance Assist.
• 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.

WARNING

• Noise may be heard when sudden braking occurs to avoid a collision.
• When other system’s warning message appears or audible warning is heard, Reverse Parking Collision- Avoidance Assist may not warn you.
• You may not hear the audible warning of Reverse Parking Collision- Avoidance Assist if the surrounding environment is too noisy.
• Reverse Parking Collision-Avoidance Assist may not work properly if the bumper has been damaged, replaced, or repaired.
• Reverse Parking Collision-Avoidance Assist may not operate normally if there is interference from strong electromagnetic waves.
• Turn off Reverse Parking Collision- Avoidance Assist when towing a trailer. If towing and moving in reverse, Reverse Parking Collision- Avoidance Assist activates when it detects a trailer.
• The brake control may not operate properly depending on the status of ESC (Electronic Stability Control). There is only a warning when:
  - The ESC (Electronic Stability Control) warning light is on.
  - ESC (Electronic Stability Control) is controlling the brake force to the wheels.
• Check the brake fluid and brake pad condition periodically. Depending on the condition, brake operation performance may reduce.

Information

Reverse Parking Collision-Avoidance Assist can detect a pedestrian or an object when:

• A pedestrian is standing behind the vehicle.
• A large obstacle, such as a vehicle, is parked in the rear center of your vehicle.
