■If the Parking Support Brake has operated
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. If
the Parking Support Brake operates unnecessarily, brake control can be
canceled 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 ena-
ble the system again ( P.318), or turn
the engine 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 moving forward), the sys-
tem will be re-enabled automatically.
■If “Parking Support Brake Unavaila-
ble” is displayed on the multi-infor- mation display and the PKSB OFF
indicator is flashing
●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 “Parking Support Brake Unavaila-
ble” and “Parking Assist Unavaila-
ble Clean Parking Assist Sensor” are displayed on the multi-informa-
tion display and the PKSB OFF
indicator is flashing
●A sensor may be covered with ice,
snow, dirt, etc. Remove the ice, snow, dirt, etc., from the sensor to return the
system to normal. If this message
continues to be displayed even after cleaning the sensor, or is displayed
even though the sensor is clean, have
the vehicle inspected by any author- ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer.
●A sensor may be frozen. Once the ice
melts, the system will return to nor-
mal.
●Water may be continuously flowing
over the sensor surface, such as in a heavy rain. When the system deter-
mines that it is normal, the system will

*: If equipped
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
Parking Suppor t Brake function (static objects)*
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 oper ation, the vehicle moving the unin-
tended direction due to the wrong shift lever being selected, or while
parking or traveling at low speeds, the system will operate to lessen
the impact with the detected static object and reduce the resulting
damage.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( P.85, 87) and all of the fol-
lowing conditions are met:
●Engine output restriction control
• The Parking Support Brake is ena- bled.
• 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• Engine output restriction control 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:
●Engine output restriction control
• The Parking Support Brake is disa-
bled. • 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 disa-
bled.
• 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.308)
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.

While the Simple Intelligent Parking
Assist System is operating, if the PKSB (Parking Support Brak e) system detects
an obstacle, the Toyota parking
assist-sensor display automatically pops up on the guidance screen ( P.304),
regardless of whether the PKSB (Park-
ing Support Brake) system is on or off. ( P.304)
Assist mode will be canceled or
stopped in the following cases.
Assist control is canceled when
 The system temperature preser-
vation function operates
 There is a system malfunction
 System determined that the
parking environment is not suita-
ble for assist to continue
When assist control is canceled,
firmly grasp the steering wheel,

shown on the display, stop the
vehicle.
This completes th e parallel parking assist mode.
 After stopping, feel free to
maneuver the vehicle to reach
the desired parking spot.
 Be sure to back up while check-
ing the area to the front and rear
of the vehicle directly and by
using the mirrors.
■Parallel parking assist mode oper-
ating conditions
●In order to operate the parallel parking
assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road
(or shoulder) while maintaining a dis-
tance of approximately 1 m (3.3 ft.) to any parked vehicles.
●The function cannot be used when the vehicle speed is approximately 30
km/h (19 mph) or higher.
●The front side sensors and rear side
sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible ( P.353), guidance is not
issued.
●If there are no parked vehicles, the
parking spot cannot be determined. Therefore, the parallel parking assist
mode cannot be operated.
●If unable to detect the environment
surrounding the parking space, the
parallel parking assist mode may not be able to operate.
●Guidance will continue until the vehi-cle speed meets or exceeds approxi-
mately 30 km/h (19 mph) or the
function is turned off using the S-IPA switch.
■Timing for pressing the S-IPA
switch
In the following cases, the assist mode may also operate during the steps taken
to park using the parallel parking assist
mode. However, in th ese cases, conduct parking procedures according to the
information on the mu lti-information dis-
play.
●In step 1 the S-IPA switch is pressed
after already passing over the target parking spot.
If the vehicle is not stopped in step 1,
pressing the S-IPA switch 1 time while
the vehicle is in motion allows you to select “Parallel Parking” and proceed
directly to step 2.
●The vehicle is moved up to the posi-
tion in step 3 without the S-IPA switch
being pressed. Then the S-IPA switch is pressed after having changed the

■Function summary
Stop so that the cent er of the target
parking spot appears nearly per-
pendicular to the vehicle. If the
space is detectable, the forward
guidance function can be used.
Furthermore, depending on the
parking space and other conditions,
multi-turn maneuvering assist con-
trol is also provided if necessary.
