Reverse Automatic Braking( RAB) System
tion.. 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.
. In the following situations, the system may not be able to detect an object correctly: – When the vehicle is approaching diagonally to an object – When the steering wheel is turned greatly
. 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.
– A sound wave with a frequency similar to the vehicle’ s system is transmitted near by.
– 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 sonar sensors or the rear bumper near the sonar sensors are 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.
Parts attached to the rear bumper near the sonar sensor: – Commercial electronic parts( fog light, fender pole, radio antenna) are attached.
– Parts that emit high frequency sound, such as a horn or speaker, are attached.
Vehicle conditions:
– Ice, snow or mud is adhered to the sonar sensors or the rear bumper near the sonar sensor.
