4RUNNER (U)●
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 will c ome within the
sensor’s detection areas before the display is shown and the wa rning
beep sounds.
• Thin posts or objects lower than the sensor may not be detected for colli-
sion 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.
■ When the system malfunctions
●If “Clean park sonar” is shown
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal. Al so, due to
the sensor being frozen at low temperatures, a malfunction disp lay may
appear or an obstacle may not be detected. If the sensor thaws out, the sys-
tem should return to normal.
● If “Check park sonar system” is shown
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
