2224-2. Driving procedures
●The parking brake is engaged.
If any of the conditions above are
detected when the brake hold sys-
tem is enabled, the system will turn
off and the brake hold standby indi-
cator light will go off. In addition, if
any of the conditions are detected
while the system is holding the
brake, a warning buzzer will sound
and a message will be shown on the
multi-information display. The park-
ing brake will then be set automati-
cally.
■Brake hold function
●If the brake pedal is left released
for a period of about 3 minutes
after the system has started hold-
ing the brake, the parking brake
will be set automatically. In this
case, a warning buzzer sounds
and a message is shown on the
multi-informat ion display.
●To turn the system off while the
system is holding the brake, firmly
depress the brake pedal and
press the button again.
●The brake hold function may not
hold the vehicle when the vehicle
is on a steep inclin e. In this situa-
tion, it may be necessary for the
driver to apply the brakes. A warn-
ing buzzer will sound and the
multi-informatio n display will
inform the driver of this situation. If
a warning message is shown on
the multi-information display, read
the message and follow the
instructions.
■When the parking brake is set
automatically while the system
is holding the brakes
Perform any of the following opera-
tions to release the parking brake.
●Depress the accelerator pedal.
(The parking brake will not be
released automatic ally if the seat
belt is not fastened.)
●Operate the parking brake switch
with the brake pedal depressed.
Make sure that the parking brake indicator light goes off. (
P.218)
■When an inspection at your
Toyota dealer is necessary
When the brake hold standby indi-
cator (green) does not illuminate
even when the brake hold switch is
pressed with the brake hold system
operating conditions met, the sys-
tem may be malf unctioning. Have
the vehicle inspected at your Toyota
dealer.
■If “Brake Hold Malfunction
Press Brake to Deactivate Visit
Your Dealer” or “Brake Hold
Malfunction Visit Your Dealer”
is displayed on the multi-infor-
mation display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
■Warning messages and buzzers
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution. If a warning mes-
sage is shown on the multi-informa-
tion display, read the message and
follow the instructions.
■If the brake hold operated indi-
cator flashes

WARNING
■When the vehicle is on a
steep incline
Take care when using the brake
hold system on a steep incline,
exercise caution. The brake hold
function may not hold brakes in
such situations.
Also, the system may not activate
depending on the angle of the
slope.

The system can detect the fol-
lowing:
Vehicles
Bicyclists
Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.244) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high,
a warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.246)

Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes i n the speed of the vehicle
ahead in order to maintain the ve hicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, system
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identifi cation of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus righ t side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the v ehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the over taking lane is
to the right but then drives to a region where the overtaking l ane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constan t speed cruising.

●Initialization may not have been
performed after a 12-volt battery
terminal was dis connected and
reconnected. Initialize the sys-
tem. ( P.290) If this message
continues to be displayed even
after initialization, have the vehicle
inspected by your Toyota dealer.
■If a 12-volt batte ry 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.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the
object and other factors, the
detection distance may shorten,
or detection may be impossible.
• Detection may be impossible if static objects draw too close to the
sensor.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibilit y that the object
will come within 11. 9 in. (30 cm)
before the display is shown and
the warning buzzer sounds.
• It might be difficult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be difficult to hear the sound of this system due to the
buzzers of other systems.
■Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Part icular instances
where this may occur are listed
below.
●There is dirt, snow or ice on a sen-
sor. (Cleaning th e sensors will
resolve this problem.)
●A sensor is froz en. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnor-
mally, or objects, such as a wall,
may not be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.

Driving
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the v ehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When an object that cannot be
detected is betw een the vehicle
and a detected object.
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due t o a collision or
other impact.
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additi onal trim strip,
etc.), bicycle carrier, or snow
plow.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.
●When driving towa rd a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots).
●When there is a ru t or hole in the
surface of the road.
●When driving on a metal cover
(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When strong winds are blowing.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.
PKSB (Parking Support
Brake) system
WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may n ot operate.
The detection cap abilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle comple tely. Addition-
ally, even if the system has
stopped the vehicle, it is neces-
sary to depress the brake pedal
immediately as brake control
will be canceled after approxi-
mately 2 seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.

Driving■ECB (Electronically Con-
trolled Brake System)
The electronically controlled
system generates braking force
corresponding to the brake
operation
■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock
when the brakes are applied
suddenly, or if the brakes are
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of
braking force after the brake
pedal is depressed when the
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or
turning on slippery road sur-
faces.
■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintain directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning

To keep driving safety and
performance, the following
systems operate automati-
cally in response to various
driving situations. Be
aware, however, that these
systems are supplementary
and should not be relied
upon too heavily when oper-
ating the vehicle.

acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
