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 ov erly 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 o r 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

sively high when entering a curve
●When entering/exiting a parking
lot, garage, car elevator, etc.
●When driving in a parking lot
●When driving through an area
where there are obstructions
which may contact your vehicle,
such as tall grass, tree branches,
a curtain, etc.
●When driving in strong wind
■Situations in which the lane
may not be detected
●When the lane is extremely wide
or narrow
●Immediately after changing lanes
or passing through an intersection
●When driving in a temporary lane
or lane regulated by construction
●When there are s tructures, pat-
terns, shadows which are similar
to lane lines in the surrounding
●When there are m ultiple white
lines for a lane line
●When the lane lines are not clear
or driving on a wet road surface
●When a lane line is on a curb
●When driving on a bright, reflec-
tive road surface, such as con-
crete
■Situations in which some or all
of the functions of the system
cannot operate
●When a malfunction is detected in
this system or a related system,
such as the brakes, steering, etc.
●When the VSC, TRAC, or other
safety related system is operating
●When the VSC, TRAC, or other
safety related system is off
■Changes in brake operation
sound and pedal response
●When the brakes have been oper-
ated, brake operation sounds may
be heard and the brake pedal
response may cha nge, but this
does not indicate a malfunction.
●When the system is operating, the
brake pedal may feel stiffer than
expected or sink. In either situa-
tion the brake pedal can be
depressed further. Further
depress the brake pedal as nec-
essary.

PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.198) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
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 possibility of a collision
is extremely high, the
brakes are automatically
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.207)
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
system in place of normal
braking operations. This sys-
tem cannot help avoid or
reduce the impact of a colli-
sion 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 followin g items care-
fully. Do not overl y rely on this
system and always drive care-
fully.

■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 drivi ng. 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 system,
turn it off using the LTA switch.

*: If equipped
When the front camera detects a sign or information
of a sign is available from the
navigation system, the sign
will be displayed on the dis-
p l a y.
Multiple signs can be dis-
played.
Depending on the specifications of
the vehicle, the number of dis-
played signs may be limited.
■Operating conditions of sign

Signs will be displayed when the fol-
lowing conditions are met:
●The system has detected a sign
In the following si tuations, a dis-
played sign may stop being dis-
played:
●When a new sign has not been
detected for a certain distance
●When the system determines that
the road being driven on has
changed, such as after a left or
right turn
■Situations in which the display
function may not operate prop-
erly
In the following situ ations, the RSA
system may not operate properly
and may not detect signs or may
display the incorrect sign. However,
this does not indicate a malfunction.
●When a sign is dirty, faded, tilted
or bent
●When the contrast of an electronic
sign is low
●When all or part of a sign is hidden
by a tree, utility pole, etc.
●When a sign is d etected by the
front camera for a short amount of
time
●When the driving state (turning,
changing lanes, etc.) is judged
incorrectly
RSA (Road Sign
Assist)*
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
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.
●Do not rely solely upon the
RSA. The RSA assists the
driver by providing road sign
information, but it is not a
replacement for the driver’s own
vision and awareness. Driving
safely is solely the responsibility
of the driver. Pay careful atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
