STARTING AND DRIVING Dual sensors The selector lever must be in any position other than "P" or "R" for these sensors to operate, however the obstacle at an angle to the front of the vehicle will also be detected while the selector lever is in "R". G31054 CAUTION 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. The steering guidance may not operate properly in the following conditions: D Tires other than those of Lexus genuine size are installed. D The steering sensor information cannot be received properly. (See "Intuitive parking assist failure warning" on page 378.) (A) Collision will be unavoidable: Collision with the detected obstacle cannot be avoided even by changing the steering. (B) Collision will be avoided by changing the steering: Collision with the obstacle can be avoided by changing the steering. (C) Collision will be avoided with the present steering angle: Even if you continue moving at the present steering angle, the distance to the obstacle within sensor detection range will not be less than about 25 cm (0.8 ft.). The dual sensors detect an obstacle in front of the vehicle or at an angle to the front of the vehicle, and estimate the distance to the obstacle and also the steering angle required. They will evaluate which of the above 3 conditions is applicable. 369
