Driving
The Parking Support Brake can be
enabled/disabled on the screen
of the multi-information display. All
of the Parking Support Brake func -
tions (static objects and rear-cross -
ing vehicles) are enabled/disabled
simultaneously. ( →P.186)
When the Parking Support Brake is dis-
abled, the PKSB OFF indicator
( →P.171) illuminates on the multi-infor-
mation display.
To re-enable the system, select on
the multi-information display, select
and turn it on.
If the system is disabl ed, it will remain
off even if the power switch is turned to
ON after the power switch has been
turned off.
WARNING
■Limitations of the Parking Sup -
port Brake system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi - cle.
Depending on the v ehicle and road
conditions, weather, etc., the system
may not operate.
The detection capabilities of sensors
and radars are limited. Always drive
while checking the safety of the sur- roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur -
roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity
of collisions. However, it may not operate in som e situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the
system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control
will be canceled after approximately 2 seconds.
●Do not attempt to test the operation of the Parking Support Brake sys -
tem yourself such as intentionally
driving to a vehicle or wall. Depending on the situations, the
system may not ope rate properly,
possibly leading to an accident.
NOTICE
■If “PKSB Unavailable” is dis -
played on the multi-information
display and the PKSB OFF indi - cator illuminates
If this message is displayed immedi -
ately after the power switch is changed to ON, ope rate the vehicle
carefully, paying attention to your sur -
roundings. It may be necessary to
drive the vehicle for a certain amount of time before the system returns to
normal. (If the syst em does not return
to normal after driving for a while, clean the sensors and their surround -
ing area on the bumpers.)

■Re-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.421), 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.
■If “Parking Support Brake Unavail -
able” is displayed on the multi-
information display and the PKSB OFF indicator illuminates
●If “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 vehi cle inspected at any authorized Toy ota retailer or
Toyota authorized repairer, or any reli -
able repairer.
●If “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 w ill 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.
