Reverse Automatic Braking ( RAB ) System ( If Equipped ) - The rear bumper is exposed to strong impact , or the rear bumper is deformed . � On a steep hill , the system ’ s automatic braking ability will be reduced . � The system is designed to avoid collisions by automatic hard braking when the vehicle ’ s reversing speed is less than approximately 3 mph ( 5 km / h ). However , the system does not guarantee that the vehicle will be able to avoid collisions in any situation . � If the vehicle is reversed at an extremely slow speed , the driver ’ s operation may be prioritized . In this case , automatic braking will not operate . � The system may not be able to detect and apply the brake with the following objects . - Sharp or thin objects such as poles , fences and ropes which may not reflect the sound wave emitted from the sonar sensor . - Objects that are too close to the rear bumper when the select lever is set to the “ R ” position . - Objects with a surface which may not reflect the sound wave emitted from the sonar sensor such as a chain link fence . � Objects the system is not designed to detect and apply brake . - Pedestrians . - Moving objects including moving vehicles . - Objects which absorbs sound waves such as cloth or snow . - Objects whose surface has a diagonal angle . - Objects that are low to the ground such as parking blocks . - Objects that are high above the ground such as objects hanging from above . - Objects that are out of range of the center of the vehicle in the horizontal direction . - Objects that are not perpendicular to the ground . - The surface of the object is uneven or wavy . � When reversing the vehicle , the functions may not be able to work properly or may cause a system malfunction if the following conditions exist .
High frequency sound from other sources are nearby :
- Horn sound from another vehicle . - Engine sound from other vehicles . - Sound of an air brake . - Vehicle detection equipment or a sonar from another vehicle .
