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 overly 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
Make sure to observe the follow-
ing precautions. The system may
not operate properly and may
lead to an unexpected accident.
When these precautions cannot
be observed, turn the system off.
●Do not damage the sensors,
and always keep them clean.
●Do not attach a st icker 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 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.

■The system can be operated
when
●The power switch is in ON.
●The intuitive parking assist func-
tion is on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●The shift position is in a position
other than P.
■If “Parking Assist Unavailable
Sensor Blocked” is displayed
on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Remove 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 an abnormality is displayed even
though there are no water droplets,
ice, snow or dirt, the sensor may be
operating abnormally. Have the
vehicle inspected by your Toyota
dealer.
■If “System Stopped See
Owner’s Manual” is displayed
on the multi-information display
Water may be continuously flowing
over the sensor surf ace, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■If “System Malfunction Visit
Your Dealer” is displayed on
the multi-info rmation display
There may be a sensor or voltage
malfunction. Have the vehicle
inspected by your Toyota dealer.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●Certain vehicle conditions and the
surrounding environment may
affect the ability of a sensor to cor-
rectly detect an object.
●Objects may not be detected if
they are too close to the sensor.
●There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detection
areas before the display is shown
and the warning beep sounds.
●It might be difficult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
●It may be difficult to hear the
buzzer if buzzers for other sys-
tems are sounding.
●If the meter malfunctions, the
buzzer may not sound.
WARNING
●Keep your tires properly
inflated.
●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 ma y 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.

3705-5. Using the driving support systems
*: Automatic buzzer mute function is enabled. (P.370)
■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
 The buzzer beeps faster as
the vehicle approaches a
static object. When the vehi-
cle comes within the approxi-
mately 1.0 ft. (30 cm) of the
static object, the buzzer will
sound continuously.
 When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
 After a buzzer begins sound-
ing, if the distance between
the vehicle and the detected a
static object does not become
shorter, the buzzer will be
muted automatically. (auto-
matic buzzer mute function)
■Adjusting the buzzer vol-
ume
The buzzer volume of the intui-
tive parking assist, RCTA (if
equipped), and RCD (if
equipped) can be adjusted all
together on of the multi-infor-
mation display. ( P.618)
■Muting a buzzer temporarily
●When an object is detected, the
temporary mute switch is dis-
played on the Multimedia Display.
Select the switch to mute a buzzer
of the intuitive parking assist,
RCTA (if equipped), and RCD (if
equipped) all together.
●Mute will be automatically can-
celed in the following situations.
• When the shift position is
changed.
• When the vehicle speed exceeds a certain speed.
• When there is a malfunction in a sensor or the system is temporar-
ily unavailable.
• When the operating function is disabled manually.
• When the power switch is turned
off.
The object warning function
informs the driver of the exis-
tence of objects along the side
of the vehicle, using a display
and buzzer, if the objects are
within the estimated path of the
vehicle.

3725-5. Using the driving support systems
■Detection of objects along the
sides of the vehicle
●Objects along the sides of the
vehicle are not instantaneously
detected. The location of objects
in relation to the vehicle is esti-
mated after they are first detected
by the front or rear side sensors,
or side cameras. Therefore, after
the power switch is changed to
ON, even if an object is along the
side of the vehicle, it may not be
detected until the vehicle has
been driven a small amount and
the side sensors or side cameras
completely scan the areas along
the sides of the vehicle.
●If a vehicle, person, animal, etc., is
detected by a side sensors or side
cameras, but then leaves the
detection area of the side sensors
or side cameras, the system will
assume the object has not moved.
WARNING
■Side sensors and side cam-
eras
In situations such as the following,
the function may not operate cor-
rectly, possibly leading to an acci-
dent. Proceed carefully.
●When starting off shortly after
the power switch is turned to
ON and a small vehicle or other
object which cannot be detected
by a front side sensor is next to
the vehicle.
In the situation shown in the fol-
lowing illustration, even if the
vehicle starts off, the vehicle on
the left will not be detected and
the object warning function will
not operate.
●When an object or person is in a
position which cannot be
detected by the side sensors or
side cameras.
●When, after the side sensors
have completed scanning the
areas along the sides of the
vehicle, a vehicle, person, or
other object approaches the
side of the vehicle and cannot
be detected.
●When the outside rear view mir-
ror is closed, the side sensors
or side cameras cannot detect
objects.
●If the 12-volt battery was dis-
charged or has been removed
and installed, fold and extend
the outside rear view mirrors.

mation display.
The RCTA can be enabled/dis-
abled through a customize set-
ting. (P.618)
When the RCTA function is off,
the driving assist information
indicator ( P.152) will illumi-
nate and a message will be dis-
played on the multi-information
display. Each time the power
switch is turned to ON, the
RCTA function is enabled.
■Outside rear view mirror indica-
tor visibility
In strong sunlight, the outside rear
view mirror indicator may be difficult
to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to
hear over loud noises, such as if the
audio system volume is high.
■Rear side radar sensors
 P.355
■Operation of the RCTA
function
The RCTA function uses rear
side radar sensors to detect
vehicles approaching from the
right or left at the rear of the
vehicle and alerts the driver of
the presence of such vehicles
by flashing the outside rear view mirror indicators and sounding a
buzzer.

■Conditions under which the
system will not detect a vehicle
The RCTA function is not designed
to detect the following types of vehi-
cles and/or objects:
●Vehicles approaching from
directly behind
●Vehicles backing up in a parking
space next to your vehicle
●Vehicles that the sensors cannot
detect due to obstructions
●Guardrails, walls, signs, parked
vehicles and similar stationary
objects
