WARNING
●The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play.
Even at slow speeds, there is a possibility that the obstacle w ill come
within the sensor’s detection areas before the display is shown and the
warning beep sounds.
• Thin posts or objects lower than the sensor may not be detecte d for col-
lision when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or
air flow noise of air conditioning system.
