QRe-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.380), 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.
QIf “Parking Support Brake Unavail-
able” is displayed on the multi-
information display and the PKSB
OFF indicator illuminates
OIf “Clean Parking Assist Sensor” is
displayed simultaneously, a sensor
may be covered with ice, snow, dirt,
etc. In this case, remove the ice,
snow, dirt, etc., from the sensor to
return the system to normal. If this
message is shown even after remov-
ing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected at
any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
OIf “Parking Assist Unavailable” is dis-
played simultaneously, water may be
continuously flowing over the sensor
surface, such as in a heavy rain.
When the system determines that it is
normal, the system will return to nor-
mal.
*: If equipped
This function will operate in situa-
tions such as the following if an
object is detected in the traveling
direction of the vehicle.
Parking Support Brake
function (static objects)
*
If the sensors detect a static
object, such as a wall, in the
traveling direction of the vehi-
cle 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 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.

Driving
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.
OBrake 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.
QThe 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:
OHybrid 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.
OBrake 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.
QDetection 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.376)
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.
QSituations in which the Parking
Support Brake function (static
objects) may not operate

3925-5. Using the driving support systems
QVSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil-
ity when swerving on slippery road
surfaces by controlling steering per-
formance.
QTrailer Sway Control
Helps the driver to control trailer
sway by selectively applying brake
pressure for individual wheels and
reducing driving torque when trailer
sway is detected.
QTRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
QActive Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
QHill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
QEPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
QE-Four (Electronic On-Demand
AWD system)
Automatically controls the drive
system such as to front-wheel drive
or AWD (all wheel drive) according
to various running conditions
including normal driving, during cor-
nering, on a uphill, when starting
off, during acceleration, on a slip-
pery roads due to snow or rain,
thus contributing to stable
operability and driving stability.
QEmergency brake signal
When the brakes are applied sud-
denly, the emergency flashers
automatically flash to alert the vehi-
cle behind.
QThe Secondary Collision
Brake (if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.
QWhen the TRC/VSC/ABS/Trail
Mode/Trailer Sway Control systems
are operating
The slip indicator light will flash while the
TRC/VSC/ABS/Trail Mode/Trailer Sway
Control systems are operating.

Therefore, the fan may stop for a while
until warm or cool air is ready to flow immediately after the “AUTO” switch is pressed.
QWindshield fog detection function
When automatic mode is set, the humid- ity sensor detects fog on the windshield and controls the air conditioning system
to prevent fog.
This feature is used to prevent ice
from building up on the windshield
and wiper blades.
Press the switch to turn the system
on/off.
The indicator comes on when the sys-
tem is on.
Vehicles with windshield wiper de-icer:
The windshield wiper de-icer will auto-
matically turn off after a period of time.
