ates,  a  buzzer  will  sound  and  a  message  will  be  displayed  on  th e 
multi-information display, to alert the driver.  
Depending  on  the  situation,  hybrid  system  output  restriction  co ntrol 
will  operate  to  either  limit  acceleration  or  restrict  output  as   much  as 
possible.

If  the  Parking  Support  Brake  determines  that  a  collision  with  a 
detected object or pedestrian is possible, the hybrid system ou tput will 
be  restricted  to  restrain  any  increase  in  the  vehicle  speed.  (H ybrid 
system output restriction control: See figure 2.)  
Additionally,  if  the  accelerator  pedal  continues  to  be  depresse d,  the 
brakes  will  be  applied  automatically  to  reduce  the  vehicle  spee d.

■If the Parking Support Brake has operated 
If  the  vehicle  is  stopped  due  to  operation  of  the  Parking  Suppo rt  Brake,  the 
Parking Support Brake will be disabled and the PKSB OFF indicat or  will  illu- 
minate.  If  the  Parking  Support  Brake  operates  unnecessarily,  br ake  control 
can be canceled by depressing the brake pedal or waiting for ap proximately 2 
seconds  for  it  to  automatically  be  canceled.  Then,  the  vehicle  can  be  oper- 
ated by depressing the accelerator pedal. 
■ Re-enabling the Parking Support Brake
To re-enable the Parking Support Brake when it has been disabled due to oper- 
ation of the Parking Support Brake, either enable the system ag ain (P. 478), 
or turn the engine switch off and then back to ON.
Additionally, if  any  of the following conditions  are met,  the s ystem  will be re- 
enabled automatically and the PKSB OFF indicator will turn off: 
● The P shift position is selected 
● The object is no longer detected in the traveling direction of the vehicle 
● The traveling direction of the vehicle changes 
■ If “Parking Support Brake Unavailable” and “Parking assist unavailable. 
Clean  parking  assist  sensor”  is  displayed  on  the  multi-informat ion  dis- 
play and the PKSB OFF indicator is flashing 
● A  sensor  may  be  covered  with  ice,  snow,  dirt,  etc.  Remove  any  ice,  snow, 
dirt, etc., from the sensor to return the system to normal.  
If this message continues to be displayed even after cleaning t he sensor, or 
is  displayed  even  though  the  sensor  is  clean,  have  the  vehicle  inspected 
any  authorized  Toyota  retailer,  Toyota  authorized  repairer,  or  any  reliable 
repairer. 
● It is possible the sensor may be frozen.  
Once the ice melts, the system will return to normal. 
● Water may be continuously flowing over the surface of the sensor.   
When  the system judges there  is no  problem,  the  system  will  ret urn  to nor- 
mal. 
■ If a 12-volt battery terminal has been disconnected and reconnected 
The  system  needs to  be initialized. To  initialize  the  system,  d rive  the  vehicle 
straight  ahead  for  5  seconds  or  more  at  a  speed  of  approximatel y  35  km/h 
(22  mph)  or  more. Additionally,  fo r  vehicles  with  the  Parking  Support  Brake 
function,  turn  the  steering  wheel  fully  to  the  left  and  right  w ith  the  vehicle 
stopped.

WARNING
■Cautions regarding the use of the system 
Do not overly rely on the system, as doing so may lead to an ac cident. 
Always drive while checking the safety of the surroundings of t he vehicle. 
Depending  on  the  vehicle  and  road  conditions,  weather,  etc.,  th e  system 
may not operate. 
The  detection  capabilities  of  sensors  and  radars  are  limited. A lways  drive 
while checking the safety of the surroundings of the vehicle. 
● The driver is solely responsible for safe driving. Always drive carefully, tak- 
ing care to observe your surroundings. The Parking Support Brak e system 
is  designed  to  provide  support  to  lessen  the  severity  of  collis ions.  How- 
ever, 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  ve hicle,  it  is 
necessary to depress the brake pedal immediately as brake contr ol 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  at tempt  such 
actions. 
■ When to disable the Parking Support 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 
● 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  addi tional  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 vehi- 
cle has been in an accident 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,  compact  spare  tire  or  an  emergency  tire  puncture 
repair kit is used

Parking Support Brake function (static  
objects)
This  function  will  operate  in  situations  such  as  the  following  if  an 
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
: If equipped
If the sensors detect a static object, such as a wall, in the t ravel- 
ing direction of the vehicle and the system determines that a c ol- 
lision  may  occur  due  to  the  vehicle  suddenly  moving  forward
due  to  an  accidental  accelerator  pedal  operation,  the  vehicle 
moving  the  unintended  direction  due  to  the  wrong  shift  lever 
being  selected,  or  while  parking  or  traveling  at  low  speeds,  th e 
system will operate to lessen the impact with the detected stat ic 
object and reduce the resulting damage.

■The Parking Support Brake function (static objects) will operate when 
The  function  will  operate  when  the  PKSB  OFF  indicator  is  not  il luminated  or 
flashing (P. 159, 161) and all of the following conditions are met: 
● Hybrid system output restriction control 
• 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 veh icle and approx- 
imately 2 to 4 m (6 to 13 ft.) away. 
• The Parking Support Brake determines that a stronger-than-norm al brake 
operation is necessary to avoid a collision. 
● Brake control 
• Hybrid system output restriction control is operating 
• The  Parking  Support  Brake  determines  that  an  immediate  brake  o pera- 
tion is necessary to avoid a collision. 
■ The  Parking  Support  Brake  function  (static  objects)  will  stop  operating 
when 
The function will stop operating if any of the following condit ions are met: 
● Hybrid system output restriction control 
• The Parking Support Brake is disabled. 
• The system determines that the collision has become avoidable  with nor- 
mal brake operation.
• The  static  object  is  no  longer  approximately  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 disabled. 
• Approximately 2 seconds have elapsed since the vehicle was sto pped by 
brake control. 
• The  brake pedal  is depressed  after  the vehicle  is  stopped  by  b rake  con- 
trol. 
• The  static  object  is  no  longer  approximately  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 Support Brake function (static objects) 
The detection range of the Parking Support Brake function (stat ic objects) dif- 
fers from the detection range of the Toyota parking assist-sens or. (P. 461)  
Therefore, even if the Toyota parking assist-sensor detects an  object and pro- 
vides a warning,  the Parking  Support Brake function (static  obj ects) may not 
start operating. 
■ Situations in which the system may not operate properly
P. 463 
■ Situations in which the system may operate even if there is no possibil- 
ity of a collision
