If the hybrid system output restric-
tion control or brake control oper-
ates, a buzzer will sound and a
message will be displayed on the
multi-information display, head-up
display (if equipped) navigation
system (if equipped) or multimedia
system (if equipped) screen, to
alert the driver.
Depending on the situation, hybrid sys-
tem output restriction control will oper-
ate to either limit acceleration or restrict
output as much as possible.

QIf the Parking Support Brake has
operated
If the vehicle is stopped due to operation
of the Parking Support Brake, the Park-
ing Support Brake will be disabled and
the PKSB OFF indicator will illuminate. If
the Parking Support Brake operates
unnecessarily, brake control can be can-
celed by depressing the brake pedal or
waiting for approximately 2 seconds for
it to automatically be canceled. Then,
the vehicle can be operated by depress-

QRe-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.380), 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.
QIf “Parking Support Brake Unavail-
able” is displayed on the multi-
information display and the PKSB
OFF indicator illuminates
OIf “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 vehicle inspected at
any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
OIf “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 will 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.

trol
• The Parking Support Brake is
enabled.
• The vehicle speed is approximately 15
km/h (9 mph) or less.
• There is a static object in the traveling
direction of the vehicle and approxi-
mately 2 to 4 m (6 to 13 ft.) away.
• The Parking Support Brake deter-
mines that a stronger-than-normal
brake operation is necessary to avoid
a collision.

trol is operating
• The Parking Support Brake deter-
mines that an immediate brake opera-
tion is necessary to avoid a collision.

tion (static objects) will stop oper-
ating when
The function will stop operating if any of
the following conditions are met:
OHybrid system output restriction con-
trol
• The Parking Support Brake is dis-
abled.
• The system determines that the colli-
sion has become avoidable with nor-
mal brake operation.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
OBrake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
QDetection range of the Parking Sup-
port Brake function (static objects)
The detection range of the Parking Sup-port Brake function (static objects) dif-
fers from the detection range of the
Toyota parking assist-sensor. (P.376)
Therefore, even if the Toyota parking
assist-sensor detects an object and pro-
vides a warning, the Parking Support
Brake function (static objects) may not
start operating.

enabled. • The vehicle speed is approximately 15 km/h (9 mph) or less.
• Vehicles are approaching from the right or left at the rear of the vehicle at a traveling speed of approximately 8
km/h (5 mph) 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 approaching vehi-
cle.
OBrake control

QDetection area of the Parking Sup-
port Brake function (rear-crossing vehicles)
The detection area of the Parking Sup-
port Brake function (rear-crossing vehi- cles) differs from the detection area of the RCTA function ( P.368). Therefore,
even if the RCTA function detects a vehicle and provides an alert, the Park-ing Support Brake function (rear-cross-
ing vehicles) may not start operating.

Suitable for driving to improve fuel
economy by more smoothly generating
torque in response to accelerator pedal
operations compared to normal mode
and restraining air conditioning system
operations (heating/cooling).
When the switch is turned to the left
while not in Eco drive mode, the system
switches to Eco drive mode and the
Eco drive mode indicator illuminates on

Press the Trail Mode switch.
Press the Trail Mode switch, to turn the
Trail Mode on. The Trail Mode indicator
light will come on the multi-information
display.
To turn the system off, press the Trail
Mode switch again.
If the tires are spinning, the slip
indicator flashes to indicate that the
Trail Mode is controlling the spin-
ning of the tires.
QTrail Mode
OTrail Mode controls the vehicle so that
it can use the maximum amount of drive force when driving on rough roads. As a result, fuel efficiency may
diminish when compared to driving with Trail Mode off.
OIf Trail Mode is continuously used for a long period of time, depending on the driving conditions, the load on
related parts increases and the sys- tem may not function correctly. In this case, “Traction Control Turned OFF”
will be shown on the multi-information display but the vehicle can be driven normally. The “Traction Control
Turned OFF” on the multi-information display will turn off after a short while
Trail Mode
Trail Mode is designed to con-
trol the spinning of the drive
wheels by integratedly con-
trolling AWD, brake and drive
force control systems. Use the
Trail Mode when driving
bumpy roads, etc.
WARNING
QBefore using Trail Mode
Make sure to observe the following precautions. Failure to observe these precautions may result in an unex-
pected accident.
OTrail mode is intended for use when driving on rough roads.
OCheck that the Trail Mode indicator is illuminated before driving.
OTrail Mode is not intended to expand the limits of the vehicle.
Thoroughly check the road condi- tions and drive with caution.
