Starting and operating/Reverse Automatic Braking System . . . . ing 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 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 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 . When reversing the vehicle, the system may not be able to properly detect objects or may cause a system malfunction if the following conditions exist High frequency sound from other 7-65 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 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 – CONTINUED –
