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

Driving
■The system can be operated
when
●The power switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift position other than P is
selected.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if static objects draw too close to the
sensor.
• There will be a short delay between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibility that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer sounds.
• It might be diffic ult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be diffi cult to hear the
sound of this sys tem due to the
buzzers of other systems.
WARNING
●Do not damage the sensors,
and always keep them clean.
●Do not attach a sticker or install
an electronic component, such
as a backlit license plate (espe-
cially fluorescent type), fog
lights, fender pole or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by your Toyota
dealer. If the fr ont or rear
bumper needs to be
removed/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.
●Do not attach a license plate
cover.
●Keep your tires properly
inflated.
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn

Driving
WARNING
●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the
TRAC/ABS/VSC/Trailer Sway
Control is activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC/Trailer
Sway Control systems are
turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC/Trailer Sway Con-
trol systems off unless necessary.
Trailer Sway Control is part of the
VSC system and will not operate
if VSC is turned off or experiences
a malfunction.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC, VSC and Trailer
Sway Control systems will not
function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Trailer Sway Control precau-
tion
The Trailer Sway Control system
is not able to red uce trailer sway
in all situations. Depending on
many factors such as the condi-
tions of the vehicle, trailer, road
surface and driving environment,
the Trailer Sway Control system
may not be effective. Refer to
your trailer owner’s manual for
information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precau-
tions.
Failing to do so may cause death
or serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try
to control trailer swaying by
turning the steering wheel.
●Begin releasing the accelerator
pedal immediately but very
gradually to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and traile r should stabi-
lize. ( P.229)
