the traveling direction of the vehi-
cle
●Change the traveling direction of
the vehicle
■If “PKSB Unavailable” is dis-
played on the multi-information
display and the PKSB OFF indi-
cator is flashing
●If this message is displayed only
when the shift lever is in any posi-
tion other than R, a sensor on the
front or rear bumper may be dirty.
Clean the sensors and their sur-
rounding area on the bumpers.
■If “PKSB Unavailable” and
“Parking Support Brake
Unavailable Remove the Dirt of
Rear Camera” is displayed on
the multi-information 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 is shown even
after removing dirt from the sen-
sor, or shown when the sensor
was not dirty to begin with, have
the vehicle inspected by your Toy-
ota 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 re turn to normal.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
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 Suppor t Brake function (static objects)*
If the sensors detect a static object, such as a wall, in the t rav-
elling 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 lever position, 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.
