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 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
●When using an automatic car

angle
●When snow, mud, etc. is attached 
to a detectable vehicle
●When driving on the following 
kinds of roads:
• Roads with sharp curves or wind- ing roads
• Roads with chang es in grade, 
such as sudden inclines or 
declines
• Roads which is slo ped to the left 
or right
• Roads with deep ruts
• Roads which are rough and 
unmaintained
• Roads which frequently undulate 
or are bumpy
●When the steering wheel is being 
operated frequently or suddenly
●When the vehicle is not in a con-
stant position within a lane
●When parts related to this system, 
the brakes, etc. are cold or 
extremely hot, wet, etc.
●When the wheels are misaligned
●When driving on slick road sur-
faces, such as when it is covered 
with ice, snow, gravel, etc.
●When the course of the vehicle 
differs from the shape of a curve
●When the vehicle speed is exces-
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.

Displays and system operation 

2184-5. Using the driving support systems
*: 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 
display
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.
