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-
ing the accelerator pedal.
■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.292), 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 “PKSB Unavailable” is displayed
on the multi-information display and the PKSB OFF indicator is on
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.
●A sensor may be covered with water drops, ice, snow, dirt, etc. Remove the
water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-mal.
Also, due to ice forming on a sensor at low temperatures, a warning message may be displayed or the sensor may
not be able to detect an object. Once the ice melts, the system will return to normal.
●If this message is displayed, a sensor on the front or rear bumper may be
dirty. Clean the sensors and their sur- rounding area on the bumpers.
●If this message continues to be dis-played even after cleaning the sensor, or is displayed even though the sen-
sor is clean, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer.

*: 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 function (static objects)*
If the sensors detect a static object, such as a wall, in the traveling
direction of the vehicle and the system determines that a colli sion
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 opera te to
lessen the impact with the detected static object and reduce th e
resulting damage.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( P.92, 441) and all of the fol- lowing conditions are met:
●Hybrid system output restriction con-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.
●Brake control
• Hybrid system output restriction con- trol is operating.• The Parking Support Brake deter-
mines that an immediate brake opera- tion is necessary to avoid a collision.
■The Parking Support Brake func-tion (static objects) will stop oper-
ating when
The function will stop operating if any of the following conditions are met:
●Hybrid 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.
●Brake 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.
■Detection 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.280) 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.
■Toyota parking assist-sensor
buzzer
Regardless of whether the Toyota park- ing assist-sensor function is enabled or
not ( P.276), if the Parking Support Brake function (static objects) is enabled ( P.292), the front or rear sensors
detect an object and brake control and hybrid system output restriction control are performed, the Toyota parking
assist-sensor buzzer will sound to notify the driver of the approximate distance to the object.

ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■E-Four (Electronic On-Demand
AWD system) (AWD models)
Automatically switches from front
wheel drive to all-wheel drive
(AWD) according to the driving con-
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, starting off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.

vehicle body and steering. • A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not indi-cate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake
pedal is operated.
●Motor sound of the brake system
heard from the front part of the vehicle when the driver’s door is opened.
●Operating sound heard from the engine compartment when one or two minutes passed after the stop of the
hybrid system.
■Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra- tions may be generated from the brake system, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard. This does not indicate a malfunc-
tion.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems
off, the systems will be automatically re- enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off,
the TRC will turn on when vehicle speed increases.If both the TRC and VSC systems are
turned off, automatic re-enabling will not occur when vehicle speed increases.
■Operating conditions of Active Cor-
nering Assist
The system operates when the following occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is
reduced to prevent the system from overheating when there is frequent steering input over an extended period
of time. The steering wheel may feel heavy as a result. Should this occur, refrain from excessive steering input or
stop the vehicle and turn the hybrid sys- tem off. The EPS system should return to normal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met, the emergency brake signal will oper-
ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h (35 mph)
●The system judges from the vehicle deceleration that it is a sudden brak-
ing operation.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will be can-
celed in any of the following situations:
●The emergency flashers are turned
on.
●The system judges from the vehicle
deceleration that is not a sudden brak- ing operation.
