Driving
■The system can be operated
when
●The engine 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 “Parking Assi st Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion 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 continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will return to normal.
●Initialization ma y not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system. (
 P.283)
If this message continues to be
displayed even afte r initialization,
have the vehicle inspected by
your Toyota dealer.
■If a battery terminal has been
disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■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.
■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
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.

2844-5. Using the driving support systems
●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.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow or ice on a sen-
sor. (Cleaning the sensors will
resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnor-
mally, or objects, such as a wall,
may not be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When an object that cannot be
detected is between the vehicle
and a detected object.
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the
vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle c arrier, or snow
plow.
●If the front of the v ehicle is raised
or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When tire chains, a compact
spare tire or an emergency tire
puncture repai r kit are used.
■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.

●When driving toward a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots).
●When there is a rut or hole in the
surface of the road.
●When driving on a metal cover
(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When strong winds are blowing.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●The vehicle is approaching a tall
or curved curb.
●Driving close to columns (H-
shaped steel beams, etc.) in multi-
story parking garages, construc-
tion sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or

■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 an
object.
When the vehicle comes
within approximately 1.1 ft.
(34 cm) of the object, the
buzzer sounds continuously.
 When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
 Even when the sensors are
operating, the buzzer will be
muted in some situations.
(automatic buzzer mute func-
tion)
■Muting the buzzer sound
●Automatic buzzer mute function
Even when the sensors are operat-
ing, the buzzer will be muted in the
following situations:
• The distance betw een the vehicle
and the detected object does not
become shorter (except when the
distance between the vehicle and
object is 1.1 ft. [34 cm] or less).
• Your vehicle is moving away from the object.
• There are no detectable objects
entering the path of your vehicle.
However, if another object is
detected or the situation changes
while the buzzer is muted, the
buzzer begins sounding again.
●To mute the buzzer sound
The buzzer can be temporarily muted by pressing of the meter
control switches while a suggestion
that says mute is available is shown
on the multi-information display.
●When the mute is canceled
Mute will be automat ically canceled
in the following situations.
• When the shift position is changed
• When the vehicle speed has reached or exceeded a certain
speed
• When the Intuitive parking assist is turned off on ce and turned on
again
• When the engine switch is turned off once and turned to ON again
■Customization
The buzzer volume can be adjusted
on the multi-information display.
