Toyota Safety Sense
3.0
The Toyota Safety Sense 3.0
consists of the driving
assist systems and contrib-
utes to a safe and comfort-
able driving experience:
WARNING
■Toyota Safety Sense 3.0
The Toyota Safety Sense 3.0
operates under the assumption
that the driver will drive safely,
and is designed to help reduce
the impact to the occupants in a
collision and assist the driver
under normal driving conditions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is solely
responsible for paying attention to
the vehicle’s surroundings and
driving safely.
■For safe use
●Do not overly rely on this sys-
tem. The driver is solely respon-
sible for paying attention to the
vehicle’s surroundings and driv-
ing safely. This system may not
operate in all situations and pro-
vided assistance is limited.
Over-reliance on this system to
drive the vehicle safely may
lead to an accident resulting in
death or serious injury.
●Do not attempt to test the oper-
ation of the system, as it may
not operate properly, possibly
leading to an accident.
●If attention is necessary while
performing driving operations or
a system malfunction occurs, a
warning message or warning
buzzer will be operated. If a
warning message is displayed
on the display, follow the
instructions displayed.
●Depending on external noise,
the volume of the audio system,
etc. it may be difficult to hear the
warning buzzer. Also, depend-
ing on the road conditions, it
may be difficult to recognize the
operation of the system.
■When it is necessary to dis-
able the system
In the following situations, make
sure to disable the system.
Failure to do so may lead to the
system not operating properly,
possibly leading to an accident
resulting in death or serious
injury.
●When the vehicle is tilted due to
being overloaded or having a
flat tire
●When driving at extremely high
speeds
●When towing another vehicle
●When the vehicle is being trans-
ported by a truck, ship, train,
etc.
●When the vehicle is raised on a
lift and the tires are allowed to
rotate freely
●When inspecting the vehicle
using a drum tester such as a
chassis dynamometer or speed-
ometer tester, or when using an
on vehicle wheel balancer
●When the vehicle is driven in a

234 4-5. Using the driving support systems
When driving on a road with
clear lane lines with the
dynamic radar cruise control
operating, lane lines and pre-
ceding and surrounding vehi-
cles are detected using the
front camera and radar sen-
sor, and the steering wheel is
operated to maintain the vehi-
cle’s lane position.
Use this function only on highways
and expressways.
If the dynamic radar cruise control
is not operating, the function will not
operate.
In situations where the lane lines
are difficult to see or are not visible,
such as when in a traffic jam, sup-
port will be provided using the path
of preceding and surrounding vehi-
cles.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, the driver will be
alerted and this function will be
temporarily canceled.
If the steering wheel is firmly
gripped, the function will begin
operating again.
When the function is operat-
ing, if the vehicle is likely to
depart from its lane, the driver
will be alerted via a display
and buzzer.
When the buzzer sounds, check
the area around the vehicle and
carefully operate the steering wheel
to move the vehicle back to the
center of the lane.

warning (P.236) is not operat-
ing.
●The vehicle is being driven in the
center of a lane.
■Temporary cancelation of func-
tions
●When the operating conditions are
no longer met, a function may be
temporarily canceled. However,
when the operation conditions are
met again, operation of the func-
tion will automatically be restored.
(P.235)
●If the operating conditions of a
function are no longer met while
the function is operating, a buzzer
may sound to indicate that the
function has been temporarily
canceled.
●The steering assist operation of
the function can be overridden by
the steering wheel operation of
the driver.
WARNING
■Before using the LTA system
●Do not overly rely on the LTA
system. The LTA system is not
a system which provides auto-
mated assistance in driving and
it is not a system which reduces
the amount of attention neces-
sary for safe driving. The driver
is solely responsible for paying
attention to their surroundings
and operating the steering
wheel as necessary to ensure
safety. Also, the driver is
responsible for taking adequate
breaks when fatigued, such as
when driving for a long time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident.
●When not using the LTA sys-
tem, turn it off using the LTA
switch.

236 4-5. Using the driving support systems
■Lane departure warning func-
tion when the LTA is operating
●Even if the LDA warning method is
changed to vibration of the steer-
ing wheel, if the vehicle deviates
from the lane while the LTA is
operating, the warning buzzer will
sound to alert the driver.
●If steering wheel operation equiv-
alent to that necessary for a lane
change is detected, the system
will determine the vehicle is not
deviating from the lane and the
warning will not operate.
■Hands off steering wheel warn-
ing operation
●When the system determines the
driver is not holding the steering
wheel, a message urging the
driver to grip the steering wheel
and the icon shown in the illustra-
tion will be displayed on the multi-
information display to warn the
driver. If the system detects that
the steering wheel is held, the
warning will be canceled. When
using the system, make sure to
grip the steering wheel firmly,
regardless of whether the warn-
ing is operating or not.
●If no operations are detected for a
certain amount of time, the warn-
ing will operate and the function
will be temporarily canceled. This
warning may also operate if the
driver only operates steering
wheel a small amount continu-
ously.
■Situations in which the hands
off steering wheel warning may
not operate properly
●Depending on the condition of the
vehicle, handle control condition
and road surface, the warning
function may not operate.
●Vehicles with LCA: In the following
situations, the system may not be
able to detect when the driver’s
hands are off the steering wheel.
• When a steering wheel cover is
installed
• When the driver is wearing gloves
• When foreign matter is attached to
the steering wheel
• When the driver is gripping the
wood trim, seam of the leather,
spokes, or other part of the steer-
ing wheel that does not have sen-
sors
●Vehicles with LCA: In the following
situations, the hands off steering
wheel warning may not operate
and the LTA function may con-
tinue operating even though the
driver’s hands are off the steering
wheel:
• When something other than a
hand is contacting the steering
wheel
• When a wide object or arms are
held across the steering wheel
The LTA will change between
ON/OFF each time the LTA
switch is pressed.
When the LTA is ON, the LTA indi-
cator will illuminate.

*: If equipped
Emergency Driving
Stop System*
The emergency driving stop
system is a system which
automatically decelerates
and stops the vehicle within
its lane if the driver
becomes unable to continue
driving the vehicle, such as
if they have suffered a medi-
cal emergency, etc.
During LTA (Lane Tracing
Assist) control, if the sys-
tem does not detect driving
operations, such as if the
driver is not holding the
steering wheel, and deter-
mines the driver is not
responsive, the vehicle will
be decelerated and stopped
within its current lane to
help avoid a collision or
reduce the impact of a colli-
sion.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving. The emer-
gency driving stop system is
designed to provide support in
an emergency where it is diffi-
cult for the driver to continue
driving, such as if they have had
a medical emergency. It is not
designed to support driving
while drowsy or in poor physical
health, or inattentive driving.
●Although the emergency driv-
ing stop system is designed to
decelerate the vehicle within its
lane to help avoid or help
reduce the impact of a collision
if the system determines that it
is difficult for the driver to con-
tinue driving, its effectiveness
may change according to vari-
ous conditions. Therefore, it
may not always be able to
achieve the same level of per-
formance. Also, if the operating
conditions are not met, this
function will not operate.
●After the emergency driving
stop system operates, if driving
becomes possible again, imme-
diately begin driving again or, if
necessary, park the vehicle on
the shoulder of the road and set
a warning reflector and flare to
warn other drivers of your
stopped vehicle.
●After this system operates, pas-
sengers should attend to the
driver as necessary and take
appropriate hazard prevention
measures, such as moving to a
place where safety can be
ensured, such as the shoulder
of the road or behind a guard-
rail.

Operation of this system is sep-
arated into 4 control states.
Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.
■Operating conditions
This system operates when all of
the following conditions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■Operation cancelation condi-
tions
In the following situations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, emergency
flasher switch, or turn signal lever
is operated)
●When the driving assist switch is
pressed while in the stop and hold
phase
●When the power switch has been
turned from ON mode to off
●Situations in which some or all of
the functions of the system cannot
operate: P.221
■LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
WARNING
●This system detects the condi-
tion of the driver through the
operation of the steering wheel.
This system may operate if the
driver is aware but intentionally
and continuously does not oper-
ate the vehicle. Also, the system
may not operate if it cannot
determine that the driver is not
responsive, such as if they are
leaning on the steering wheel.

Warning phase 2

274 4-5. Using the driving support systems
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.
When the vehicle is decelerat-
ing, the brake lights may illumi-
nate, depending on the road
conditions, etc.
After entering the deceleration
stop phase, a buzzer will sound
continuously and a message will
be displayed to warn the driver,
and the vehicle will slowly decel-
erate and stop. After the vehicle
stops, the system will enter the
stop and hold phase.
After the vehicle is stopped, the
parking brake will be applied
automatically. After entering the
stop and hold phase, the buzzer
will continue sounding continu-
ously and the emergency flash-
ers (hazard lights) will flash to
warn other drivers of the emer-
gency.
■Restricted functions after the
operation is canceled
After shifting to the deceleration
stop phase, the following functions
will not be available until the hybrid
system is re-started even though
the emergency driving stop system
is canceled:
●LTA
●LCA (if equipped)

*: If equipped
The Advanced Park is a system
which assists in a safe and
smooth parking or exiting from a
parking space by displaying the
blind spots around the vehicle
and the target parking spot
through a bird’s eye view, deliv-
ering operation guidance
through displays and buzzer
operation, and changing the
shift position, operating the
steering wheel, accelerator
pedal, and brake pedal.
Additionally, the panoramic view
monitor*can display the area in
front, behind, and from above
the vehicle, helping confirm the
condition of the area around the
vehicle.
The turn signal lights will blink
automatically when the parking
assistance starts until the vehi-
cle reaches the target parking
spot, to notify people around the
vehicle that parking is being per-
formed.
Depending on the condition of
the road surface or the vehicle,
the distance between the vehi-
cle and a parking space, etc., it
may not be possible to assist in
parking in the target space.

WARNING
■Cautions regarding the use of
the system
The recognition and control capa-
bilities for this system are limited.
The driver should always drive
safety by always being responsi-
ble without over relying on the
system and have a understanding
of the surrounding situations.
●As with a normal vehicle, take
care to observe your surround-
ings while the vehicle is moving.
●Always pay attention to the
vehicle’s surroundings while the
system is operating and
depress the brake pedal as nec-
essary to slow or stop the vehi-
cle.
●When parking, make sure that
the vehicle can be parked in the
target parking space before
beginning operation.
●Depending on the condition of
the road surface or the vehicle,
the distance between the vehi-
cle and a parking space, etc., it
may not be possible to detect a
parking space or the system
may not be able to provide
assistance to the point the vehi-
cle is fully parked.
●This system will guide the vehi-
cle to appropriate positions for
changing the direction of travel,
however, if you feel that the
vehicle is approaching too close
to an adjacent parked vehicle at
any time, depress the brake
pedal and change the shift posi-
tion. However, if this is per-
formed, the number of times the
vehicle changes direction may
increase, and the vehicle may
be parked at an angle.
