• The shift lever is in other than P.
• The vehicle speed is approximately 10 km/h (6 mph) or less.
O Rear corner and rear center sensors:
The shift lever is in R.
Q Sensor detection information
O The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
O Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
O Detection may be impossible if the objects draw too close to the sensor.
O There will be a short delay between object detection and display. Even at
low speeds, there is a possibility that the object will come within the sensor’s
detection areas before the display is shown and the warning beep sounds.
O Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
O It might be difficult to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.
Q Objects which the system may not properly detect
The shape of the object may prevent the sensor from detecting it. Pay partic-
ular attention to the following objects:
O Wires, fences, ropes, etc.
O Cotton, snow and other materials that absorb sound waves
O Sharply-angled objects
O Low objects
O Tall objects with upper sections projecting outwards in the direction of your
vehicle
O Moving objects such as people or animals
People may not be detected if they are wearing certain types of clothing.
Q Situations in which the system may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect objects. Particular instances where this
may occur are listed below.
O There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
