316 5-4 . Using the driving support systems
■ Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting it . Pay particular attention to the following objects :
● Wires , fences , ropes , etc .
●Cotton , snow and other materials that absorb sound waves
● Sharply-angled objects ●Low objects
●Tall objects with upper sections projecting outwards in the direction of your vehicle
People may not be detected if they are wearing certain types of clothing .
■ Situations in which the system may not operate properly
Certain vehicle conditions and the
surrounding environment may affect the ability of a sensor to correctly detect objects . Particular instances
where this may occur are listed below .
●There is dirt , snow , water drops or ice on a sensor . ( Cleaning the sensors will resolve this problem .)
●A sensor is frozen . ( Thawing the area will resolve this problem .)
In especially cold weather , if a sensor is frozen the sensor display may be displayed abnormally ,
or objects , such as a wall , may not be detected .
●When a sensor or the area around a sensor is extremely hot or cold .
●On an extremely bumpy road , on an incline , on gravel , or on grass .
●When vehicle horns , vehicle detectors , motorcycle engines , air brakes of large vehicles , the clearance sonar of other vehicles or other devices which produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain .
●If objects draw too close to the sensor .
●When a pedestrian is wearing clothing that does not reflect ultrasonic waves ( ex . skirts with gathers or frills ).
●When objects that are not perpendicular to the ground , not perpendicular to the vehicle traveling
direction , uneven , or waving are in the detection range .
●Strong wind is blowing
●When driving in inclement weather such as fog , snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle , motorcycle , bicycle or pedestrian cuts in front of the vehicle or runs out from the side of the vehicle
●If the orientation of a sensor has
been changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed , such as a towing eyelet , bumper protector ( an additional trim strip , etc .), bicycle carrier , or snow plow
●If the front of the vehicle is raised or lowered due to the carried load
●If the vehicle cannot be driven in a stable manner , such as when the vehicle has been in an accident or is malfunctioning
●When a tire chains , compact spare tire or an emergency tire puncture repair kit is used
