STARTING AND DRIVING When the intuitive parking assist determines that the collision will be avoided with the present steering angle: The indicator will come on in green. However, if the sensors detect and determine an obstacle at an angle to the front of the vehicle, the indicator will not come on. Beeps (except for avoidable collisions at the present steering angle): As distance to the obstacle gets closer, the interval of the intermittent sound gets shorter, and then finally to a continuous sound when the distance between the vehicle and the obstacle is less than about 25 cm (0.8 ft.). Rear corner sensors G31068 CAUTION D When an obstacle is detected within about 25 cm (0.8 ft.) from the vehicle, the dual sensors will change the determination to an unavoidable collision. D With long obstacles such as walls, the decision of the sensor may change as the obstacle gets closer; from certain avoidance to avoidance if steering is changed; from certain avoidance to unavoidable collision; and there are also times when the decision will be changed from avoidance if steering is changed, to certain collision. When you move your vehicle, be sure to confirm a safe distance around your vehicle with your eyes and drive slowly, or an accident or injury may result.
