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
wash

WARNING
■To prevent malfunction of the
radar sensors
Observe the following precau-
tions. Failure to do so may lead to
a radar sensor not operating prop-
erly, possibly leading to an acci-
dent resulting in death or serious
injury.
●Keep the radar sensors and
radar sensor covers clean at all
times.
Clean the front of a radar sensor
or the front or back of a radar sen-
sor cover if it is dirty or covered
with water drople ts, snow, etc.
When cleaning the radar sensor
and radar sensor cover, use a soft
cloth to remove di rt so as to not
damage them.
Type A
Type B

●Do not attach a ccessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a radar sensor or radar sensor
cover and their surrounding
area.
●Do not subject a radar sensor or
its surrounding area to impact.
If a radar sensor, the front grille,
or front bumper has been sub-
jected to a imp act, have the
vehicle inspected by your Toy-
ota dealer.
●Do not disassemble the radar
sensors.
●Do not modify or paint the radar
sensors or radar sensor cover,
or replace them with anything
other than Toyota genuine parts.
●In the following situations, recal-
ibration of the radar sensors will
be necessary. For details, con-
tact your Toyota dealer.
• When a radar sensor is removed and installed, or
replaced
• When the front bumper or the front grille has been replaced
■To prevent malfunction of the
front camera
Observe the following precau-
tions.
Failure to do so may lead to the
front camera not operating prop-
erly, possibly leading to an acci-
dent resulting in death or serious
injury.
●Always keep the windshield
clean.
• If the windshield is dirty or cov-
ered with an o ily film, water
droplets, snow, etc., clean the
windshield.

WARNING

1884-5. Using the driving support systems
■Situations in which the sensors
may not operate properly
●When the height or inclination of
the vehicle has been changed due
to modifications
●When the windshield is dirty,
fogged up, cracked or damaged
●When the ambient temperature is
high or low
●When mud, water, snow, dead
insects, foreign matter, etc., is
attached to the front of the sensor
●When in inclement weather such
as heavy rain, fog, snow, or a
sandstorm
●When water, snow, dust, etc. is
thrown up in front of the vehicle, or
when driving through mist or
smoke
●When the headlig hts are not illu-
minated while driving in the dark,
such as at night o r when in a tun-
nel
●When the lens of a headlight is
dirty and illumination is weak
●When the headlights are mis-
aligned
●When a headlight is malfunction-
ing
●When the headlights of another
vehicle, sunlight, or reflected light
shines directly into the front cam-
era
●When the brightness of the sur-
rounding area changes suddenly
●When driving near a TV tower,
broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical
noise may be present
●When a wiper blade is blocking
the front camera
●When in a location or near objects
which strongly reflect radio waves,
such as the following:
• Tunnels
• Truss bridges
• Gravel roads
• Rutted, snow-covered roads
• Walls
• Large trucks
• Manhole covers
• Guardrail
• Metal plates
●When near a step or protrusion
●When a detectable vehicle is nar-
row, such as a small mobility vehi-
cle
●When a detectable vehicle has a
small front or rear end, such as an
unloaded truck
●When a detectable vehicle has a
low front or rear end, such as a
low bed trailer
●When a detectable vehicle has
extremely high ground clearance
WARNING
■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.

be heard and the brake pedal
response may change, 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.191) 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.200)

Driving
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)
Vehicles
 Bicycles
*
Pedestrians
 Motorcycles
*
*: 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 pr e-collision sys-
tem is designed to help avoid or
help reduce the im pact 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 followi ng items care-
fully. Do not overl y rely on this
system and always drive care-
fully.
