9-44 Driving and Operating An obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle. When the distance is less than 30 cm (12 in) the beeping is a continuous tone for five seconds. Objects Detected by Both the Front and Rear Sensors (If Equipped) In general, if objects are detected at the same time near both the front and rear bumpers while backing up, the beeps only sound to indicate that objects are close to the rear bumper. However, if an object is very close to the front bumper while the vehicle is backing up and at the same time there is another object further not as close to the rear bumper, then the beeps only sound to indicate the object that is closer to the front bumper. WARNING (Continued) speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with parking assist, always check the area around the vehicle and check all mirrors before moving forward or backing. Turning the System On and Off The URPA/UFRPA system can be turned on and off using the park assist button located next to the radio. How the System Works When the shift lever is moved into R (Reverse), the sensors are automatically turned on. A single tone sounds to indicate the system is working. After the vehicle is shifted out of R (Reverse), the rear sensors are turned off and the front sensors (if equipped) stay on until the vehicle is above a speed of 8 km/h (5 mph). For the front park assist system to be active again without shifting into R (Reverse), the park assist button next to the radio must be pressed. See "Turning the System On and Off" later in this section. The indicator light next to the park assist button lights up when the system is on and turns off when it has been disabled. When the system is off, a message displays on the Driver Information Center (DIC). The message disappears after a short period of time. The system defaults to the on setting each time the vehicle is started.
