Starting and operating / Reverse Automatic Braking ( RAB ) system 7-75
– The sonar sensor and the area near the sonar sensor are being damaged . – 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 sound from another vehicle – Engine sound from other vehicles – Sound of an air brake – Vehicle detection equipment or a sonar from another vehicle – 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 : – Extremely high or extremely low temperatures in which the area near the sonar sensor becomes too hot or too cold to operate . – The rear bumper near the sonar sensors is exposed to heavy rain or a significant amount of water . – Fog , snow or sandstorm , etc . – Air is moving rapidly such as when a strong wind is blowing .
