When driving
●In the following situations, the intuitive parking assist may not function correctly,
possibly leading to an accident.
• There is ice, snow or mud on the sensors. (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 abnor-
mal 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 nois e, 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 sensor s 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.
■Obstacles that may not be detected correctly
The following obstacles may not be detected.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Objects where the upper section projects out over the lower section.
•Low objects.

changing position of the antenna, differences in signal strength and surrounding
objects, such as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.
