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.

WARNING
■When stopped on a slippery
road
The system cannot stop the vehi-
cle when the gripping ability of the
tires has been exceeded. Do not
use the system when stopped on
a slippery road.
NOTICE
■When parking the vehicle
The brake hold s ystem is not
designed for use when parking
the vehicle for a long period of
time. Turning the power switch off
while the system i s holding the
brake may release the brake,
which would cause the vehicle to
move. When operating the power
switch, depress the brake pedal,
shift the shift lever to P and set
the parking brake.

Driving
Canada
1 The side marker, park-
ing, tail, license plate, instru-
ment panel lights, daytime
running lights and LED
accessory lights (if equipped)
( P.225) turn on.
2 The headlights and all
lights listed above (except
daytime running lights) turn
on.
3 The headlights, daytime
running lights, LED acces-
sory lights (if equipped)
( P.225) and all the lights
listed above turn on and off
automatically.
■AUTO mode can be used when
The power swit ch is in ON.
■Daytime running light system
●Vehicles with multi-LED head-
lights and LED projector head-
lights with bulb type front turn
signal lights: The daytime running
lights illuminate u sing the same
lights as the low beam headlights
and illuminate d immer than the low beam headlights.
●Vehicles with LED projector head-
lights with LED type front turn sig-
nal lights: The daytime running
lights illuminate using the same
lights as the parking lights and illu-
minate brighter than the parking
lights.
●To make your vehicle more visible
to other drivers
during daytime
driving, the daytime running lights
turn on automatically when all of
the following conditions are met.
(The daytime running lights are
not designed for use at night.)
• The hybrid system is operating
• The parking brake is released
• For the U. S. A.: The headlight
switch is in the , or
*
position
• For Canada: The headlight switch
is in the or
* position
*: When the surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers greater durability
and consumes less electricity, so
it can help improve fuel economy.
■LED accessory lights (if
equipped)
To make your vehicle more visible
to other drivers dur ing daytime driv-
ing, the LED accesso ry lights turn
on automatically when the parking
brake is released while the hybrid
system is operating.
When the parking lights are turned
on, the LED accessory lights dim.
■Headlight control sensor (if
equipped)
The sensor may not function prop-
erly if an object is placed on the sen-

2444-5. Using the driving support systems
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)

WARNING
■Limitations of the pre-colli-
sion system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking
operations under any circum-
stances. This system will not
prevent collisions or lessen col-
lision damage or injury in every
situation. Do not overly rely on
this system. Failure to do so
may lead to an accident, result-
ing in death or serious injury.
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
P.248
• Conditions under which the sys- tem may not operate properly:
P.250
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 seconds. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■When to disable the pre-colli-
sion system
In the following situations, disable
the system, as it may not operate
properly, possibly leading to an
accident resulting in death or seri-
ous injury:
●When the vehicle is being towed

2484-5. Using the driving support systems
●Pre-collision brake assist
●Pre-collision braking
If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur-
rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. ( P.250)
The illustration sh ows an image of
detectable objects.
■Conditions under which the
system may operate even if
there is no possibility of a colli-
sion
●In some situations such as the fol- lowing, the system may determine
that there is a possibility of a fron-
tal collision and operate.
• When passing a detectable
object, etc.
• When changing lanes while over- taking a detectable object, etc.
• When approaching a detectable object in an adjacent lane or on
the roadside, such as when
changing the course of travel or
driving on a winding road
• When rapidly closing on a detect- able object, etc.
• When approaching objects on the roadside, such as detectable
objects, guardrails, utility poles,

• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera
is misaligned
●In some situations such as the fol-
lowing, sufficient braking force
may not be obtained, preventing
the system from p erforming prop-
erly:
• If the braking functions cannot
operate to their full extent, such as
when the brake parts are
extremely cold, ext remely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces-
sively worn, imprope r tire inflation
pressure, etc.)
• When the vehicle is being driven
on a gravel road or other slippery
surface
• When the road surface has deep
wheel tracks
• When driving on a hill road
• When driving on a road that has
inclines to the left or right
■If VSC is disabled
●If VSC is disabled ( P.362), the
pre-collision brak e assist and pre-
collision braking functions are also
disabled.
●The PCS warning light will turn on
and “VSC Turned Off Pre-Colli-
sion Brake System Unavailable”
will be displayed on the multi-
information display.

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.
