(Wiping the sensors will resolve this problem.) • The sensor area is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnormal display, or obstacles may not be detected. • The vehicle angle is especially wide. • In harsh sunlight or intense cold weather. • When driving on bumpy, sloped or gravel roads, or over grass. • If there is something producing ultrasonic waves nearby, such as another vehicle's horn, motorcycle engine noise, air braking sound from heavy-duty vehicles, or another vehicle using the intuitive parking assist. • In heavy rain, or if water is splashed on the sensors. • If a commercial fender pole or radio antenna is installed. • If towing eyelet is installed on your vehicle. • If moving towards a high curb or a curb corner. • Objects such as signs may cause the detection distance to shorten. • The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected initially, but as they draw closer, they may cease to be detected. • If obstacles draw too close to the sensor.
