PKSB (Parking Support  
Brake)*
The Parking Support Brake  
system consists of the follow- 
ing functions that operate  
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 oper- 
ates to urge the driver to take  
evasive action. If the system  
determines that the possibility  
of a collision with a detected  
object is extremely high, the  
brakes are automatically  
applied to help avoid the colli- 
sion or help reduce the impact  
of the collision.

Brake) system
WARNING
■Cautions regarding the use of  the system 
Do not overly rely on the system, as  doing so may lead to an accident. 
Always drive while checking the  
safety of the surroundings of the vehi- cle. 
Depending on the vehicle and road  
conditions, weather, etc., the system  may not operate. 
The detection capabilities of sensors  
and radars are limited. Always drive  while checking the safety of the sur-roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,  
taking care to observe your sur- roundings. The Parking Support Brake system is designed to pro- 
vide 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  
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 intention- 
ally driving the vehicle into the  direction of a wall, etc. Never attempt such actions.
■When to disable the Parking Sup-port Brake 
In the following situations, disable the  Parking Support Brake as the system may operate even though there is no  
possibility of a collision.
●When inspecting the vehicle using 
a chassis roller, chassis dynamo or  free roller

NOTICE
■If “PKSB Unavailable” is dis-played on the multi-information  
display and the PKSB OFF indi- cator is on 
If this message is displayed immedi- 
ately after the power switch is  changed to ON, operate the vehicle carefully, paying attention to your sur- 
roundings. It may be necessary to  drive the vehicle for a certain amount of time before the system returns to  
normal. (If the system is not return to  normal after driving for a while, clean the sensors and their surrounding  
area on the bumpers.)

celed by depressing the brake pedal or  
waiting for approximately 2 seconds for  it to automatically be canceled. Then, the vehicle can be operated by depress- 
ing the accelerator pedal.
■Re-enabling the Parking Support  Brake 
To re-enable the Parking Support Brake  
when it is disabled due to operation of  the Parking Support Brake, either enable the system again ( P.292), or  
turn the power switch off and then back  to ON. Additionally, if the object becomes no longer in the traveling  
direction of the vehicle or if the traveling  direction of the vehicle changes (such as changing from moving forward to  
backing up, or from backing up to mov- ing forward), the system will be re-enabled automatically.
■If “PKSB Unavailable” is displayed  
on the multi-information display  and the PKSB OFF indicator is on 
If the vehicle is stopped due to operation  
of the Parking Support Brake, the Park- ing Support Brake will be disabled and the PKSB OFF indicator will illuminate.
●A sensor may be covered with water drops, ice, snow, dirt, etc. Remove the  
water drops, ice, snow, dirt, etc., from  the sensor to return the system to nor-mal. 
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 system will return to normal.
●If this message is displayed, a sensor on the front or rear bumper may be  
dirty. Clean the sensors and their sur- rounding area on the bumpers.
●If this message continues to be dis-played even after cleaning the sensor, or is displayed even though the sen- 
sor is clean, have the vehicle  inspected by any authorized Toyota retailer or Toyota authorized repairer,  
or any reliable repairer.

Parking Support Brake function (static objects)*
If the sensors detect a static  object, such as a wall, in the traveling  
direction of the vehicle and the system determines that a colli sion  
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 being selected, or  
while parking or traveling at low speeds, the system will opera te to  
lessen the impact with the detected static object and reduce th e  
resulting damage.

The function will operate when the  PKSB OFF indicator is not illuminated or  
flashing ( P.92, 441) and all of the fol- lowing conditions are met:
●Hybrid system output restriction con-trol• The Parking Support Brake is  
enabled. • The vehicle speed is approximately 15 km/h (9 mph) or less. 
• There is a static object in the traveling  direction of the vehicle and approxi-mately 2 to 4 m (6 to 13 ft.) away. 
• The Parking Support Brake deter- mines that a stronger-than-normal brake operation is necessary to avoid  
a collision.
●Brake control
• Hybrid system output restriction con- trol is operating.• The Parking Support Brake deter- 
mines that an immediate brake opera- tion is necessary to avoid a collision.
■The Parking Support Brake func-tion (static objects) will stop oper- 
ating when 
The function will stop operating if any of  the following conditions are met:
●Hybrid system output restriction con- 
trol • The Parking Support Brake is dis-abled. 
• The system determines that the colli- sion has become avoidable with nor-mal brake operation. 
• The static object is no longer approxi- mately 2 to 4 m (6 to 13 ft.) away from the vehicle or in the traveling direction  
of the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.• Approximately 2 seconds have  
elapsed since the vehicle was  stopped by brake control.• The brake pedal is depressed after  
the vehicle is stopped by brake con- 
trol. • The static object is no longer approxi-mately 2 to 4 m (6 to 13 ft.) away from  
the vehicle or in the traveling direction  of the vehicle.
■Detection range of the Parking Sup-port Brake function (static objects) 
The detection range of the Parking Sup- port Brake function (static objects) dif-fers from the detection range of the  
Toyota parking assist-sensor. ( P.280)  Therefore, even if the Toyota parking assist-sensor detects an object and pro- 
vides a warning, the Parking Support  Brake function (static objects) may not start operating.
■Toyota parking assist-sensor  
buzzer 
Regardless of whether the Toyota park- ing assist-sensor function is enabled or  
not ( P.276), if the Parking Support  Brake function (static objects) is enabled ( P.292), the front or rear sensors  
detect an object and brake control and  hybrid system output restriction control are performed, the Toyota parking  
assist-sensor buzzer will sound to notify  the driver of the approximate distance to the object.
