WARNING
■Intuitive parking assist pre-
cautions
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 use the sensor at
speeds in excess of 6 mph (10
km/h).
●The sensors’ detection areas
and reaction times are limited.
When moving forward or revers-
ing, check the areas surround-
ing the vehicle (especially the
sides of the vehicle) for safety,
and drive slowly, using the
brake to control the vehicle’s
speed.
●Do not install accessories near
the bumpers as those areas are
within the sensors’ detection
areas.
●The area directly under the
bumpers is not detected.
Thin posts or objects lower than
the sensor may not be detected
when approached, even if they
have been detected once.
■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.
●The vehicle is equipped with a
commercial fender pole, wire-
less antenna or fog lights.
●The front or rear bumper or a
sensor receives a strong
impact.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)

■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be co vered 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 a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle inspected by your
Toyota dealer.
■If “Parking Assist 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 retu rn to normal.
●Initialization may not have been
performed after a 12-volt battery
terminal was disconnected and
reconnected. Initialize the sys-
tem. ( P.294) If this message
continues to be displayed even
after initialization, have the vehicle
inspected by your Toyota dealer.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
The system needs to be initialized.
WARNING
●Towing eyelets (if equipped) are
installed.
●A backlit license plate is
installed.
■When using the intuitive park-
ing assist
In the following s ituations, the
system may not function correctly
due to a sensor mal function, etc.
Have the vehicle checked by your
Toyota dealer.
●The intuitive parking assist
operation display flashes or
shows continuously, and a
buzzer sounds when no objects
are detected.
●If the area around a sensor col-
lides with something, or is sub-
jected to strong impact.
●If the bumper or grille collides
with something.
●If the display flashes or is dis-
played continuously and a
buzzer does not sound, except
when the mute function has
been turned on.
■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
c los e to th e se ns or s a s do ing so
may cause a sens or to malfunc-
tion.

Driving
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 possibilit y that the object
will come within 11. 9 in. (30 cm)
before the display is shown and
the warning buzzer 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 sound of this system due to the
buzzers of other systems.
■Conditions under which the
function may not function cor-
rectly
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.
●A sensor is cove red in any way.
●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.
●The vicinity of the vehicle is noisy
due to vehicle horns, motorcycle
engines, air brakes of large vehi-
cles, or other lou d noises produc-
ing ultrasonic waves.
●There is another vehicle equipped
with parking assist sensors in the
vicinity.
●A sensor is coated with a sheet of
spray or heavy rain.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall
or curved curb.
●If objects draw too close to the
sensor.
■Objects which may not be prop-
erly detected
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.
■Certification (Canada only)
This ISM device complies with
Canadian ICES-001.

2984-5. Using the driving support systems
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 w hile a suggestion
that says mute is available is shown
on the multi-info rmation display.
●When the mute is canceled
Mute will be automat ically canceled
in the followin g situations.
• When the shift position is changed
• When the vehicle speed has reached or excee ded a certain
speed
• When the Intuitive parking assist
is turned off once and turned on
again
• When the power switch is turned
off once and tur ned to ON again

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.
