4-5. Using the driving support systems

4

Driving

(such as those used at railroad crossings, 

toll gates and parking lots)

●

When there is a rut or hole in the surface 

of the road

●

When driving on a metal cover (grating), 

such as those used for drainage ditches

●

When driving up or down a steep slope

●

If a sensor is hit by a large amount of 

water, such as when driving on a flooded 

road

●

There is dirt, snow, water drops or ice on 

a sensor. (Cleaning the sensors will 

resolve this problem.)

●

A sensor is coated with a sheet of spray 

or heavy rain

●

When driving in inclement weather such 

as fog, snow or a sandstorm

●

When strong winds are blowing

●

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

●

If the front of the vehicle is raised or low-

ered due to the carried load

●

If the orientation of a sensor has been 

changed due to a collision or other 

impact

●

The vehicle is approaching a tall or 

curved curb

●

Driving close to columns (H-shaped steel 

beams, etc.) in multi-story parking 

garages, construction sites, etc.

●

If the vehicle cannot be driven in a stable 

manner, such as when the vehicle has 

been in an accident or is malfunctioning

●

On an extremely bumpy road, on an 

incline, on gravel, or on grass

●

When a tire chains, compact spare tire or 

an emergency tire puncture repair kit is 

used

Detection range of the sensors

Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)

The diagram shows the detection range of 
the sensors. Note that the sensors cannot 
detect objects that are extremely close to 
the vehicle.
The range of the sensors may change 
depending on the shape of the object, etc.
