The Parking Support Brake can
be enabled/disabled on the
multi-information display. All of
the Parking Support Brake func-
tions (static objects and
rear-crossing vehicles) are
enabled/disabled simultane-
ously.
Use the meter control switches
to enable/disable the parking
support brake. (P.102)

and then press .
When the Parking Support Brake is
disabled, the PKSB OFF indicator
( P.76) illuminates on the instru-
ment cluster.
To re-enable the system when it was disabled, select on the
multi-information
display, select
and turn it on. If the system is dis-
abled, it will remain off even if the
engine switch is turned to ON after
the engine switch has been turned
off.
If the engine output restriction con-
trol or brake control operates, a
buzzer will sound and a message
will be displayed on the audio sys-
tem screen and multi-information
display, to alert the driver.
Depending on the situation, engine
output restriction control will oper-
ate to either limit acceleration or
restrict output as much as possible.

played on the multi-informa-
tion display and the PKSB

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-

●The shift lever is in P.
●Drive with no opera tion targets in
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 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 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.

■The Parking Support Brake
function (rear-crossing vehi-
cles) will operate when
The function will op erate when the
PKSB OFF indicator is not illumi-
nated or flashing ( P.75, 76) and all
of the following conditions are met:
●Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is approxi-
mately 9 mph (15 km/h) or less.
• Vehicles which are approaching from the right or left at the rear of
the vehicle at a traveling speed of
approximately 5 mph (8 km/h) or
more.
• The shift lever is in R.
• The Parking Support Brake deter- mines that a stronger than normal
brake operation is necessary to
avoid a collision with an approach-
ing vehicle.
●Brake control
• Engine output restriction control is operating.
• The Parking Support Brake deter- mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.
Parking Suppor t Brake function (rear-crossing
vehicles)*
If a rear radar sensor detects a vehicle approaching from the
right or left at the rear of the vehicle and the system deter-
mines that the possibility of a collision is high, this function
will perform brake control to reduce the likelihood of an
impact with the approaching vehicle.
