Driving 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. Certain add-on devices such as large trailer hitches, bike or surfboard racks and any device that may block the normal detection zone of the RSS system may create false beeps. The system will assist the driver in detecting certain objects while the vehicle slowly moves in reverse at speeds less than 6 mph (10 km/h). The system is not effective at speeds greater than 6 mph (10 km/h) and may not detect certain angular or moving objects. The system detects obstacles up to a maximum range of 20 feet (6 meters) at speeds above 2 mph (3 km/h) or 10 feet (3 meters) at speeds below 2 mph (3 km/h) behind the rear bumper with a decreased coverage area at the outer corners of the bumper, (refer to the figures for approximate zone coverage areas). As you move closer to the obstacle, the rate of the tone increases. When the distance to the obstacle is less than 18 inches (45.0 cm), 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. Whenever a warning is received, the radio volume will be lowered to a volume that allows the tones to be heard. The radio volume will return to the previous level after the warning goes away. The extended rear park assist is automatically enabled when the gear selector is placed in R (Reverse) and the ignition is ON.
