WARNING
■Cautions regarding the use of
the system
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 always
responsible for paying attention to
the vehicle’s surroundings and
driving safely.
■To ensure the system can
operate properly
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not damage the sensors,
and always keep them clean.
●Do not attach a sticker or install
an electronic component, such
as a backlit licen se plate (espe-
cially fluorescent type), fog
lights, fender po le 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 front 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.

3905-5. Using the driving support systems
■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).
●The shift lever is in a position
other than P.
■If “Clean Parking Assist Sen-
sor” is displayed on the multi-
information display
A sensor may be covered with ice,
snow, dirt, etc. R emove the ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle insp ected by your
Toyota dealer.
■If “Parking Assi st Unavailable”
is displayed on the multi-infor-
mation display
Water may be con tinuously flowing over the sensor surface, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■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 9.8 in. (25 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.
■Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular atte ntion to the fol-
lowing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
WARNING
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sens or to malfunc-
tion.

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.

■If the Parking Support Brake
has operated
If the vehicle is stopped due to oper-
ation of the Parki ng Support Brake,
the Parking Suppor t Brake will be
disabled and the PKSB OFF indica-
tor will illuminate. If the Parking Sup-
port Brake operates unnecessarily,
brake control can be canceled by depressing the brake pedal or wait-
ing for approximate
ly 2 seconds for
it to automatically be canceled.
Then, the vehicle can be operated
by depressing the accelerator pedal.
■Re-enabling the Parking Sup-
port Brake
To re-enable the Parking Support
Brake when it is disabled due to
operation of the Parking Support
Brake, either enable the system
again ( P.397), or turn the power
switch off and then back to ON.
Additionally, if the object becomes
no longer in the traveling direction of
the vehicle or if the traveling direc-
tion of the vehicle changes (such as
changing from moving forward to
backing up, or from backing up to
moving forward), t he system will be
re-enabled automatically.

Support Brake function (static
objects) differs from the detection
range of the intuitive parking assist.
(  P.392) Therefore, even if the
intuitive parking assist detects an
object and provides a warning, the
Parking Support Brake function
(static objects) may not start operat-
ing.

■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on d irt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Corn ering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●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 particula r care when the
indicator light flashes.
■When the TRAC/VSC/Trailer
Sway Control systems are
turned off
