Driving
■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.

Object
Calculated vehicle route
When the vehicle is moving, the side sensors or side cameras can
detect objects. While the vehicle is moving, if a detected object can
no longer be detected by the side sensors or side cameras, the loca-
tion of the object relative to the vehicle is estimated. If the object is
determined to be in the estimated path of the vehicle, the object
warning function will operate.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehicle
are not detected.
2 Objects are detected as the vehicle is moving.
3 Even though the objects are outsi de of the detection area of the
side sensors or side cameras, a warning is displayed and a
buzzer sounds.
■The intuitive parking assist
object warning function is oper-
ational when
●The vehicle moves about 23.0 ft.
(7 m) after the hybrid system is
started.
