ing for approximately 2 seconds for 
it to automatically be canceled. 
Then, the vehicle can be operated 
by depressing the accelerator pedal.
■Re-enabling the Parking Sup-
port 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.279), or turn  the engine 
switch to OFF and then back to ON. 
Additionally, if the object becomes 
no longer in the traveling direction of 
the vehicle or if the traveling direc-
tion of the vehicle changes (such as 
changing from moving forward to 
backing up, or from backing up to 
moving forward) , the system will be 
re-enabled automatically.
■If “PKSB Unavailable” is dis-
played on the multi-information 
display and the PKSB OFF indi-
cator is flashing
If this message is displayed, a sen-
sor on the front or rear bumper may 
be dirty. Clean the sensors and their 
surrounding area on the bumpers.
■If “PKSB Unavailable” and 
“Parking Assist Unavailable 
Clean Parking Assist Sensor” 
are displayed on the multi-infor-
mation display and the PKSB 
OFF indicator is flashing
●A sensor may be covered with ice, 
snow, dirt, etc. In this case, 
remove the ice, s now, dirt, etc., 
from the sensor to return the sys-
tem to normal. If this message is 
shown even after removing dirt 
from the sensor, or shown when 
the sensor was not  dirty to begin 
with, have the vehicle inspected at 
your Toyota dealer.
●A sensor may be frozen. Once the 
ice melts, the sys tem will return to 
normal.
●Water may be continuously flow-
ing over the sensor surface, such 
as in a heavy rain. When the sys- tem determines that it is normal, 
the system will retu
rn to normal.
■If a battery terminal has been 
disconnected and reconnected
The system needs to be initialized. 
To initialize the system, drive the 
vehicle straight ahead for 5 seconds 
or more at a speed of approximately 
22 mph (35 km/h) or more.

■The Parking Support Brake 
function (static object) will 
operate when
The function will op erate when the 
PKSB OFF indicato r is not illumi-
nated or flashing ( P.77, 79) and 
all of the followin g conditions are 
met:
●Engine output restriction control
• The Parking Support Brake is  enabled.
• The vehicle speed is approxi-
mately 9 mph  (15 km/h) or less.
• There is a static object in the trav- eling direction o f the vehicle and 
approximately 6 to 13 ft. (2 to 4 m) 
away.
• The Parking Support Brake deter-
mines that a stronger-than-nor-
mal brake operation is necessary 
to avoid a collision.
●Brake control
• Engine output restri ction control is 
operating
• The Parking Support Brake deter- mines that an immediate brake 
operation is necessary to avoid a 
collision.
■The Parking Support Brake 
function (static objects) will 
stop operating when
The function will st op operating if 
any of the following  conditions are 
met:
●Engine output restriction control
• The Parking Support Brake is dis- abled.
• The system determines that the 
collision has beco me avoidable 
with normal brake operation.
• The static object is no longer 
approximately 6 to 13 ft. (2 to 4 m) 
away from the vehicle or in the 
traveling directi on 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 control.
• The static object is no longer  approximately 6 to 13 ft. (2 to 4 m) 
away from the vehicle or in the 
traveling direction of the vehicle.
■Detection range of the Parking 
Support Brake function (static 
objects)
The detection range of the Parking 
Support Brake function (static 
objects) differs from the detection 
range of the intuiti ve parking assist. 
(  P.275) Therefore, even if the 
intuitive parking assist detects an 
object and provides a warning, the 
Parking Support Brake function 
(static objects) may  not start operat-
ing.
■Situations in wh ich the Parking 
Support Brake function (static 
objects) may not operate
When the shift lever is in N
■Situations in which the system 
may not operate properly
 P.273
■Situations in which the system 
may operate even if there is no 
possibility of a collision

*: If equipped
This function will operate in situations such as the following if a vehi-
cle is detected in the traveling direction of the vehicle.
■When reversing, a vehicle is approaching and the brake pedal 
is not depressed, or is depressed late
 P.263
■The Parking Support Brake 
function (rear-crossing vehi-
cles) will operate when
The function will op erate when the 
PKSB OFF indicator  is not illumi-
nated or flashing ( P.77, 79) and 
all of the followin g conditions are 
met:
●Engine output restriction control
• The Parking Support Brake is 
enabled.
• The vehicle speed is approxi-
Parking Support Brake function (rear-crossing 
vehicles)*
If a rear radar sensor detects a vehicle approaching from the 
right or left at the rear of the vehicle and the system deter-
mines that the possibility of a collision is high, this function 
will perform brake control to reduce the likelihood of an 
impact with the approaching vehicle.

• Vehicles are approaching from the  right or left at the rear of the vehi-
cle at a traveling speed of approx-
imately 5 mph (8  km/h) or more.
• The shift lever is in R.
• The Parking Support Brake deter-
mines that a stronger than normal 
brake operation is necessary to 
avoid a collision with an approach-
ing vehicle.
●Brake control
• Engine output restri ction control is 
operating
• The Parking Support Brake deter- mines that an emergency brake 
operation is necessary to avoid a 
collision with an approaching vehi-
cle.
■The Parking Support Brake 
function (rear-crossing vehi-
cles) will stop operating when
The function will st op operating if 
any of the following  conditions are 
met:
●Engine output restriction control
• The Parking Support Brake is dis- abled.
• The collision becomes avoidable  with normal brake operation.
• A vehicle is no longer approaching 
from the right or left at the rear 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 control.
• A vehicle is no longer approaching  from the right or left at the rear of 
the vehicle.
■Detection area of the Parking 
Support Brake function (rear-
crossing vehicles)
The detection area of the Parking 
Support Brake function (rear-cross-
ing vehicles) differs from the detec- tion area of the RCTA function 
(
 P.267). Therefore, even if the 
RCTA function detects a vehicle 
and provides an alert, the Parking 
Support Brake function (rear-cross-
ing vehicles) may not start operat-
ing.
