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.

Parking Support Brake fu nction (static objects)*
If the sensors detect a static object, such as a wall, in the t rav-
eling direction of the vehicle and the system determines that a
collision may occur due to the vehicle suddenly moving for-
ward due to an accidental accelerator pedal operation, the
vehicle moving the unintended 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.

■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintai n directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer 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.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort needed to turn the steering
wheel.
■Dynamic Torque Control
AWD system (AWD models)
(if equipped)
Automatically controls the drive
system such as to front-wheel
drive or AWD (all wheel drive)
according to various running
conditions including normal driv-
ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■Dynamic Torque Vectoring
AWD system (AWD models)
(if equipped)
Automatically controls the drive
system such as to front-wheel
drive or AWD (all wheel drive)
according to various running
conditions including normal driv-
ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
Also, drive torque distribution is
precisely controlled during cor-
nering, contributing to improve-
ments in operability and
stability.
