08 SIENNA_U (L/O 0801) Perceptible area A: Approximately B: Approximately 1800 mm (70.9 in.) 850 mm (33.5 in.) CAUTION Perceptible area is limited as shown in the previous illustration. Check the area around the vehicle before driving and start driving slowly. The maximum detection distance of the sensor varies depending on the size of the obstacle. The sensor can detect a large obstacle, such as a wall, up to 1800 mm (70.9 in.) away. However, the detection distance of a thin obstacle, such as a pole, is less than 1800 mm (70.9 in.). D The Toyota park assist system is intended as an aid to assist you to park and is not a substitute for your personal judgment. Make your driving decisions based on your observations. D Do not attach accessories or other objects to the vehicle within the sensor perceptible area. Doing so may cause the system to malfunction, which might result in an accident. D In certain situations, the system will not function properly and when the vehicle approaches certain objects, the system will not detect those objects. Therefore, always observe the area around the vehicle and do not rely solely on the system. 1: Rear corner sensors 2: Rear sensors 391 2008 SIENNA from Aug. '08 Prod. (OM45455U)
