Reverse Automatic Braking ( RAB ) system 371
– The ground clearance is changed due to the vehicle ’ s loading condition or modification .
– Ice , snow or mud is adhered to the rear bumper near the sonar sensor .
– The rear bumper is exposed to strong impact , or the rear bumper is deformed .
. When the 8-inch audio / navigation system is performing a software update , the Reverse Automatic Braking ( RAB ) system may not display the following items on the audio / navigation screen until the update is complete . – Display Icon on / off Function – Distance Indicator Image – Warning Message
. 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 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 . – Pedestrians – Moving objects including moving vehicles – Objects which absorb 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 .
. The system may not be able to properly detect objects or may cause a system malfunction when the following conditions exist .
High frequency sound from other sources are nearby : – Horn sounds from other vehicles . – Engine sounds from other vehicles . – Sounds of air brakes – Vehicle detection equipment or a sonar from other vehicles
– A sound wave with a frequency similar to the vehicle ’ s system is transmitted nearby .
– A vehicle equipped with the same system is reversing toward your reversing direction .
Weather conditions :
