Driving
If a sensor is dirty, the position of the 
dirty sensor will be shown on the 
display.
Also, due to ice forming on a sensor 
at low temperatures, a warning 
message may be displayed or the 
sensor may not be able to detect an 
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed 
even if the sensor is clean, there 
may be a sensor malfunction. Have 
the vehicle inspected by your Toyota 
dealer.
■Sensor detection information
●The sensors may be able to only 
detect objects near the front and 
rear bumpers.
●The following situations may occur 
during use.
• Depending on the shape of the 
object and other  factors, the 
detection distance may shorten, or 
detection may be impossible.
• Detection may be impossible if  static objects draw too close to the 
sensor.
• After the static object detection,  there will be a short delay before a 
graphic is shown on displays, and 
warning buzzer sounds. Even at 
low speeds, there  is a possibility 
that the object will come within the 
sensor’s detecti on areas before 
the display is shown and the warn-
ing beep sounds.
• 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.
• It may be difficult to hear the  buzzer if buzzers for other sys-
tems are sounding.
■Objects which the system may 
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it. 
Pay particular attention to the follow-
ing 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 direc-
tion 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. Part icular 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 froz en. (Thawing the 
area will resolve this problem.) 
In especially cold weather, if a 
sensor is frozen the sensor dis-
play 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 clear-
ance sonar of ot her vehicles or 
other devices which produce ultra-
sonic waves are near the vehicle
●A sensor is coated with a sheet of 
spray or heavy rain. 
Page 262 of 500
2624-5. Using the driving support systems
●If objects draw too close to the 
sensor.
●When a pedestrian is wearing 
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the v ehicle 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 betw een 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 t o a collision or 
other impact
●When equipment that may 
obstruct a sensor is installed, such 
as a towing eyelet, bumper pro-
tector (an additi onal 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 or compact 
spare tire is used
■Situations in which the system 
may operate even if there is no 
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate 
even though there is no possibility of 
a collision.
●When driving on a narrow road
●When driving towa rd a banner, 
flag, low-hanging branch or boom 
barrier (such as those used at rail-
road crossings, toll gates and 
parking lots)
●When there is a ru t 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 clear-
ance sonar of ot her vehicles or 
other devices which produce ultra-
sonic waves are near the vehicle
●If the front of the v ehicle is raised 
or lowered 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, con-
struction 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 or compact

■Detection range of the sen-
sors
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 clos e to the vehicle.
The range of the sensors may 
change depending on the shape of 
the object, etc.

■Buzzer operation and 
approximate distance to 
object
A buzzer sounds when the sen-
sors are operating.
 The buzzer beeps faster as 
the vehicle approaches an 
object. When the vehicle 
comes within approximately 
1.0 ft. (30 cm) of the object, 
the buzzer sounds continu-
ously.
 When 2 or more sensors 
simultaneously detect a static 
object, the buzzer sounds for 
the nearest object.
 Even when the sensors are 
operating, the buzzer will be 
muted in some situations. 
(automatic buzzer mute func-
tion)
■Adjusting the buzzer vol-
ume
The buzzer volume can be 
adjusted on the multi-informa-
tion display.
The buzzer volume of the intui-
tive parking assist and RCTA (if 
equipped) can be adjusted all 
together on   of the  multi-information display.

■Muting a buzzer
When an object is detected, the 
temporary mute switch is dis-
played on the audio system 
screen.
Select the switch to mute the 
buzzer of the intuitive parking 
assist and RCTA (if equipped) 
all together.
Mute will be canceled automati-
cally in the following situations:
 When the shift lever is 
changed.
 When the vehicle speed 
exceeds a certain speed.
 When there is a malfunction 
in a sensor or the system is 
temporarily unavailable.
 When the operating function 
is disabled manually.
 When the engine switch is 
turned off.

PKSB (Parking Sup-
por t Brake)*
The PKSB (Parking Support 
Brake) consists of the fol-
lowing functions that oper-
ate when driving at a low 
speed or backing up, such 
as when parking. When the 
system determines that the 
possibility of a collision 
with a detected object is 
high, a warning operates to 
urge the driver to take eva-
sive action. If the system 
determines that the possi-
bility of a collision with a 
detected object is extremely 
high, the brakes are auto-
matically applied to help 
avoid the collision or help 
reduce the impact of the col-
lision.

Brake) system
WARNING
■Cautions regarding the use of 
the system
Do not overly rely on the system, 
as doing so may lead to an acci-
dent.
Always drive while checking the 
safety of the surroundings of the 
vehicle.
Depending on the vehicle and 
road conditions, weather, etc., the 
system may n ot operate.
The detection cap abilities of sen-
sors and radars are limited. 
Always drive while checking the 
safety of the surroundings of the 
vehicle.
●The driver is solely responsible 
for safe driving. Always drive 
carefully, taking care to observe 
your surroundings. The PKSB 
(Parking Support Brake) system 
is designed to provide support 
to lessen the severity of colli-
sions. However, it may not oper-
ate in some situations.
●The PKSB (Parki ng Support 
Brake) system is not designed 
to stop the vehicle completely. 
Additionally, even if the system 
has stopped the vehicle, it is 
necessary to depress the brake 
pedal immediately 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.

(P.449)
When the PKSB (Parking Sup-
port Brake) function is off, the 
driving assist information indica-
tor ( P.74) will illuminate.
When turned OFF (disabled), the 
PKSB (Parking Supp ort Brake) will 
be disabled and will not be enabled 
until the setting is changed to ON 
again in multi-information display. 
(The function will no t be reenabled 
by operating the engine switch.)
If the engine output restriction con-
trol or brake control operates, a 
buzzer will sound  and a message 
will be displayed on  the multi-infor-
WARNING
■When to disable the PKSB 
(Parking Support Brake) sys-
tem
In the following situations, disable 
the PKSB (Parking Support 
Brake) as the system may oper-
ate even though there is no possi-
bility of a collision.
●When inspecting  the vehicle 
using a chassis roller, chassis 
dynamo or free roller
●When loading the vehicle onto a 
boat, truck or other transport 
vessel
●If the suspension has been 
modified or tires of a size other 
than specified are installed
●If the front of the vehicle is 
raised or lowered due to the 
carried load
●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
●When using automatic car 
washing devices
●If the vehicle cannot be driven in 
a stable manner, such as when 
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a 
sporty manner or off-road
●When the tires are not properly 
inflated
●When the tires are very worn
●When a tire chains or compact 
spare tire is used
●When your vehicle is towing a 
trailer or during emergency tow-
ing
■Precautions for the suspen-
sion
Do not modify the suspension of 
the vehicle. If the height or tilt of 
the vehicle is c hanged, the sen-
sors may not be  able to detect 
detectable objects and the system 
may not operate correctly, possi-
bly leading to an accident.

If the vehicle is stopped due to oper-
ation of the PKSB (P arking Support 
Brake), the PKSB (P arking Support 
Brake) will be disabled and the driv-
ing assist informa tion indicator will 
illuminate. If the PKSB (Parking 
Support Brake) op erates unneces-
sarily, brake control can be canceled 
by depressing the brake pedal or 
waiting for approximately 2 sec-
onds for it to automatically be can-
celed. Then, the vehicle can be 
operated by depress ing the acceler-
ator pedal.
■Re-enabling the PKSB (Parking 
Support Brake) system
To re-enable the PKSB (Parking 
Support Brake) when it has been 
disabled due to operation of the 
PKSB (Parking Support Brake), 
either enable the system again  (
 P.266), or turn the engine switch 
off and then back to ON.
Additionally, if a ny of the following 
conditions are m et, the system will 
be re-enabled automatically and the 
driving assist inf ormation indicator 
will turn off:
●The P shift position is selected
●The object is no longer detected in 
the traveling direction of the vehi-
cle
●The traveling direction of the vehi-
cle changes

2704-5. Using the driving support systems
If the sensors detect a static object, such as a wall, in the travelling 
direction of the vehicle and the system determines that a collision 
may occur due to the vehicle suddenly moving forward due to an 
accidental accelerator pedal operation, the vehicle moving the unin-
tended direction due to the wrong shift position, or while park ing or 
traveling at low speeds, the system will operate to lessen the  impact 
with the detected static object and reduce the resulting damage .
The system operates in the follow ing situations when a static object 
is detected in the traveling direction of the vehicle.
■When traveling at a low speed and the brake pedal is not 
depressed, or is depressed late
■When the accelerator pedal is depressed excessively
