●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 materi als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility th at the obstacle will come within the sensor’s detection
areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sens or may not be detected for collision when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of air conditioning system.
■If “Clean Parking Assist Sensor” is di splayed on the multi-information display
A sensor may be dirty or covered with snow or ic e. In such cases, if it is removed from the
sensor, the system should return to normal. Also, due to the sensor being frozen at low
temperatures, a malfunction display may appear or an obstacle may not be detected. If
the sensor thaws out, the syst em should return to normal.
■If “Parking Assist Malfunction” is di splayed on the multi-information display
Depending on the malfunction of the sensor, the device may not be working normally.
