clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).

dicular to the ground, not perpen-
dicular to the v ehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing.

cuts in front of the vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due t o a collision or
other impact.

obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additi onal trim strip,
etc.), bicycle carrier, or snow
plow.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.
●When driving towa rd a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and

surface of the road.
●When driving on a metal cover
(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When strong winds are blowing.

obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional 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 vehicle has been in an acci-
dent or is malfunctioning.
●When the vehicle is driven in a

NOTICE
■If “PKSB Unavailable” is dis-
played on the multi-informa-
tion display and the PKSB
OFF indicator is flashing
If this message is displayed
immediately after the engine
switch is changed to ON, operate
the vehicle carefully, paying atten-
tion to your surroundings. It may
be necessary to drive the vehicle
for a certain amount of time
before the system returns to nor-
mal. (If the system does not return
to normal after dr iving for a while,
clean the sensors and their sur-
rounding area on the bumpers.)
Enabling/Disabling the
Parking Support Brake

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.

*: 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 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.
