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, 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 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

●

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

●

speed or backing up, such as when 
parking. When the system deter-
mines that a collision with a 
detected object or pedestrian is 
high, a warning operates to urge 
the driver to take evasive action. If 
the system determines that the pos-
sibility of a collision with a detected 
object or pedestrian is extremely 
high, the brakes are automatically 
applied to help avoid the collision or

WARNING

■

Cautions regarding the use of the sys-

tem

Do not overly rely on the system, as 

doing so may lead to an accident. Always 

drive while checking the safety of the sur-

roundings of the vehicle.

Depending on the vehicle and road con-

ditions, weather, etc., the system may not 

operate.

The detection capabilities of sensors, 

radars and camera are limited. Always 

drive while checking the safety of the sur-

roundings of the vehicle.

●

Do not attempt to test the operation of 

this system by driving the vehicle 

toward another vehicle, a person or 

detected object, as it may not operate 

properly, possibly leading to an acci-

dent.

●

The driver is solely responsible for safe 

driving. Always drive carefully, taking 

care to observe your surroundings. 

The Parking Support Brake system is 

designed to provide support to lessen 

the severity of collisions. However, it 

may not operate in some situations.

●

The Parking Support Brake system is 

not designed to stop the vehicle com-

pletely. Additionally, even if the system 

has stopped the vehicle, it is necessary 

to depress the brake pedal immedi-

ately as brake control will be canceled 

after approximately 2 seconds.

●

It is extremely dangerous to check the 

system operations by intentionally 

driving the vehicle into the direction of 

a wall, etc. Never attempt such actions.

290

4-5. Using the driving support systems

The Parking Support Brake can be 
enabled/disabled on the multi-informa-
tion display. All of the Parking Support 
Brake functions (static objects, 
rear-crossing vehicles, and rear pedes-
trians) are enabled/disabled simultane-
ously.

Precautions for the suspension

Do not modify the suspension of the 

vehicle. If the height or tilt of the vehicle is 

changed, the sensors may not be able to 

detect detectable objects and the system 

may not operate correctly, possibly lead-

ing to an accident.
