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 si tuations, 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
sporty manner or off-road

2925-5. Using the driving support systems
●When the driver is wearing a face
mask
●When the driver is laughing or
their eyes are only slightly open
●When the driver’s eyes, nose,
mouth, or shape of their face is
blocked
●When the driver is wearing
makeup which makes it difficult to
detect their eyes, nose, mouth, or
shape of their face
●When the driver’s eyes are
blocked by the frame of eye-
glasses, sunglasses, hair, etc.
●When there is a device inside the
vehicle that radiates near infrared
rays, such as a non-genuine
driver monitoring system.
*: If equipped
During controlled driving, the
driver monitor camera detects
the position and direction the
driver is facing, and whether
their eyes are opened or closed.
Through this, the system deter-
mines if the driver is checking
their surroundings and if the
driver can perform driving oper-
ations.
■Warning function
In situations such as the follow-
ing, a buzzer will sound and a
message will be displayed to
warn the driver.
 When the system determines
that the driver is not paying
attention to the road or their
eyes are closed
 When the driver’s face cannot
be detected or the system
determines that the driver has
poor driving posture

Basic functions

2945-5. Using the driving support systems
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)
Vehicles
 Bicycles
*
Pedestrians
 Motorcycles
*
Walls
*: Detected as a detectable object
only when being ridden.
■Pre-collision warning
When the system determines
that the possibility of a collision
is high, a buzzer will sound and
an icon and warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
If the detectable object is a vehi-
cle, moderate braking will be
performed with the warning.
If the system determines that
the accelerator pedal is strongly
depressed, the following icon
and message will be displayed
on the multi-information display.
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.
Never use the pre-collision sys-
tem in place of normal braking
operations. This system cannot
help avoid or reduce the impact of
a collision in every situation.
Over-reliance on this system to
drive the vehicle safely may lead
to an accident resulting in death
or serious injury.
●Although the pre-collision sys-
tem is designed to help avoid or
help reduce the impact of a col-
lision, its effectiveness may
change according to various
conditions. Therefore, it may not
always be able to achieve the
same level of performance.
Read the following items care-
fully. Do not overly rely on this
system and always drive care-
fully.

■Pre-collision brake assist
If the system determines that
the possibility of a collision is
high and the brake operation by
the driver is insufficient, the
braking power will be increased.
■Pre-collision brake control
If the system determines that
the possibility of a collision is
extremely high, the brakes are
automatically applied to help
avoid the collision or reduce the
impact of the collision.
■Emergency steering assist
If the system determines that
the following conditions are met,
assistance will be provided to
help enhance vehicle stability
and prevent lane departure.
During assistance, in addition to
the pre-collision warning, the fol-
lowing icon will be displayed on
the multi-information display.
 The possibility of a collision is
high
 There is sufficient space
within the lane to perform
evasive steering maneuvers
 The driver is operating the steering wheel
Vehicles with active steering
function: The brakes and steer-
ing are controlled to help avoid a
collision or reduce the impact of
a collision, regardless of the
evasive steering maneuvers
performed by the driver.
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.
■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.

intersection and crossing the
path of an oncoming vehicle
