Toyota Safety Sense
The Toyota Safety Sense con-
sists of the driving assist sys-
tems and contributes to a safe
and comfortable driving expe-
rience:
WARNING
■Toyota Safety Sense
The Toyota Safety Sense operates under the assumption that the driver will drive safely, and is designed to
help reduce the impact to the occu- pants in a collision and assist the driver under normal driving condi-
tions. As there is a limit to the degree of recognition accuracy and control performance that this system can pro-
vide, do not overly rely on this sys- tem. 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 system. The driver is solely responsible for paying attention to the vehicle’s sur-
roundings and driving safely. This system may not operate in all situa-tions and provided assistance is
limited. Over-reliance on this sys- tem to drive the vehicle safely may lead to an accident resulting in
death or serious injury.
●Do not attempt to test the operation
of the system, as it may not operate properly, possibly leading to an accident.
●If attention is necessary while per-forming driving operations or a sys-
tem 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, depending on the road conditions, it may be difficult to recognize the operation of the sys-
tem.
■When it is necessary to disable
the system
In the following situations, make sure to disable the system.
Failure to do so may lead to the sys- tem 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 speedometer tes-
ter, or when using an on vehicle wheel balancer
●When the vehicle is driven in a sporty manner or off-road
●When using an automatic car wash

*: 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
determines if the driver is checking
their surroundings and if the driver
can perform driving operations.
■Warning function
In situations such as the following,
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 pos-
ture.

WARNING
●Although the pre-collision system is designed to help avoid or help
reduce the impact of a collision, its effectiveness may change accord-ing to various conditions. Therefore,
it may not always be able to achieve the same level of perfor-mance. Read the following items
carefully. Do not overly rely on this system and always drive carefully.

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, assis-
tance will be provided to help
enhance vehicle stability and pre-
vent lane departure. During assis-
tance, in addition to the pre-
collision warning, the following icon
will be displayed on the multi-infor-
mation 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 steer-
ing wheel
During assistance, the pre-collision
warning will operate and a mes-
sage will be displayed to warn the
driver.
■Intersection collision avoid-
ance support (left/right turn)
In situations such as the following,
if the system determines that the
possibility of a collision is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
 When turning left/right and an
oncoming pedestrian or bicycle
is detected
■Intersection collision avoid-
ance support (crossing vehi-
cles)
At an intersection, etc., if the sys-
tem determines that the possibility
of a collision with an approaching

■Acceleration Suppression at
Low Speed
When driving at a low speed, if the
accelerator pedal is strongly
depressed and the system deter-
mines that there is a possibility of a
collision, EV system output will be
restrained or the brakes will be
applied weakly to restrict accelera-
tion. During operation, a buzzer will
sound and a warning indicator and
message will be displayed on the
multi-information display.
“Accelerator Pedal is Pressed”
WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●Pre-collision braking function is not intended for remain stopped. If the vehicle is stopped by pre-collision
braking function, the driver should operate the brakes as necessary.
●The pre-collision braking function may not operate if certain opera-tions 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 tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision brake control.
■Acceleration Suppression at Low Speed
If the steering wheel is being turned,
the system may determine that the driver is taking evasive action and possibly prevent the Acceleration
Suppression at Low Speed function from operating.
■Emergency steering assist
●The emergency steering assist will be canceled when the system
determines that lane departure pre- vention control has completed.
●Depending on operations per-formed by the driver, emergency steering assist may not operate or
operation may be canceled.
• If the accelerator pedal is
depressed strongly, the steering wheel is turned heavily, the brake pedal is depressed, or the turn sig-
nal lever is operated, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.
