273 4-5. Using the driving support systems 4 Dr iv ing ● Initialization may not have been performed after a battery terminal was disconnected and recon- nected. Initialize the system. ( If this message continues to be displayed even after initialization, have the vehicle inspected by your Toyota dealer. ■ If a battery terminal has been disconnected and reconnected The system needs to be initialized. To initialize the system, drive the vehicle straight ahead for 5 seconds or more at a speed of approximately 22 mph (35 km/h) or more. ■ Sensor detection information ● The sensor’s detection areas are limited to the areas around the vehicle’s front and rear bumpers. ● The following situations may occur during use. • Depending on the shape of the object and other factors, the detection distance may shorten, or detection may be impossible. • Detection may be impossible if static objects draw too close to the sensor. • There will be a short delay between static object detection and display (warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 11.9 in. (30 cm) before the display is shown and the warning buzzer sounds. • It might be difficult to hear the buzzer due to the volume of the audio system or air flow noise of the air conditioning system. • It may be difficult to hear the sound of this system due to the buzzers of other systems. ■ Objects which the system may not properly detect The shape of the object may pre- vent the sensor from detecting it. Pay particular attention to the fol- lowing objects: ● Wires, fences, ropes, etc. ● Cotton, snow and other materials that absorb sound waves ● Sharply-angled objects ● Low objects ● Tall objects with upper sections projecting outwards in the direc- tion of your vehicle People may not be detected if they are wearing certain types of cloth- ing. ■ Situations in which the system may not operate properly Certain vehicle conditions and the surrounding environment may affect the ability of a sensor to correctly detect objects. Particular instances where this may occur are listed below. ● There is dirt, snow or ice on a sen- sor. (Cleaning the sensors will resolve this problem.) ● A sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the sensor dis- play may be displayed abnor- mally, or objects, such as a wall, may not be detected. ● When a sensor or the area around a sensor is extremely hot or cold. ● On an extremely bumpy road, on an incline, on gravel, or on grass. ● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehicles, the clear- ance sonar of other vehicles or other devices which produce ultra- sonic waves are near the vehicle. |
