Driving To help avoid personal injury, always use caution when in R (Reverse) and when using the rear park assist. This system is not designed to prevent contact with small or moving objects. The system is designed to provide a warning to assist the driver in detecting objects to avoid damaging the vehicle. The system may not detect smaller objects, particularly those close to the ground. The system will assist the driver in detecting certain objects while the vehicle slowly moves in reverse at speeds less than 10 km/h (6 mph). The system is not effective at speeds greater than 10 km/h (6 mph) and may not detect certain angular or moving objects. The system detects obstacles within approximately five meters (16.4 ft.) behind the rear bumper with a decreased coverage area at the outer corners of the bumper. In the figure, the smaller objects behind the vehicle represent the near-vehicle and bumper corner coverage area of the park aid system and the large object represents the extended coverage area. As you move closer to the obstacle, the rate of the tone increases. When the distance to the obstacle is less than 45.0 cm (18 in.), the tone will sound continuously. If the system detects an object that is approaching the vehicle at such as rate that rapid braking is required, a very high rate tone will sound. If this tone is heard while reversing, the driver is advised to slow down immediately until the tone either changes to a slower rate or stops. 200
