4-5. Using the driving support systems

●

Cotton, snow and other materials that 

absorb sound waves

●

Sharply-angled objects

●

Low objects

●

Tall objects with upper sections project-

ing outwards in the direction of your vehi-

cle

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 sur-

rounding environment may affect the ability 

of a sensor to correctly detect objects. Par-

ticular instances where this may occur are 

listed below.

●

There is dirt, snow 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 dis-

played abnormally, or objects, such as a 

wall, may not be detected.

●

When a sensor or the area around a sen-

sor 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 eye-

let, bumper protector (an additional trim 

strip, etc.), bicycle carrier, or snow plow

●

If the front of the vehicle is raised or low-

ered 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

■

Situations in which the system may 

operate even if there is no possibility of a 

collision

In some situations, such as the following, the 

system may operate even though there is no 

possibility of a collision.

●

When driving on a narrow road

●

When driving toward a banner, flag, 

low-hanging branch or boom barrier
