Toyota RAV 4 2015 Service Manual page 257

The shape of the obstacle may prevent a sensor from detecting it. Pay par-
●
ticular 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 sensor.
• There will be a short delay between obstacle detection and indicator.
Even at slow speeds, there is a possibility that the obstacle will come
within the sensor's detection areas before the indicator comes on and the
warning 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
■
● The indicator for the malfunctioning sensor turns on and the vehicle indica-
tor turns off while the buzzer sounds for approximately 7 seconds.
If the corner and center indicators turn on and remain on after that, first
check the status of the sensor. If the indicators stay on even though there is
no mud, ice or snow on the sensor, the sensor may be malfunctioning. Have
the vehicle inspected by your Toyota dealer.
The indicator for the malfunctioning sensor flashes and the vehicle indicator
●
turns off while the buzzer sounds for approximately 7 seconds.
If the corner and center indicators flash after that, the sensor may be mal-
functioning. Have the vehicle inspected by your Toyota dealer.
