285 4-5. Using the driving support systems 4 Dr iving RX350/RX350L_U ■ Operational conditions frontal collision with a vehicle or pedestrian is high. ● Pre-collision warning: detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].) • The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more. ● Pre-collision brake assist: detecting a pedestrian, vehicle speed is between approximately 20 and 50 mph [30 and 80 km/h].) • The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 20 mph (30 km/h) or more. ● Pre-collision braking: detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].) • The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more. The system may not operate in the following situations: ● If a battery terminal has been disconnected and reconnected and then the vehicle has not been driven for a certain amount of time ● If the shift lever is in R ● If VSC is disabled (only the pre-collision warning function will be operational) ■ Pedestrian detection function ■ Cancelation of the pre-collision braking be canceled: ● The accelerator pedal is depressed strongly. ● The steering wheel is turned sharply or abruptly. The pre-collision system detects pedestrians based on the size, profile, and motion of a detected object. However, a pedestrian may not be detected depending on the surrounding brightness and the motion, posture, and angle of the detected object, preventing the system from operating properly. ( |
