■Operation of the RCTA
function
The RCTA function uses 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 indica-
tors and sounding a buzzer.

■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’ d etection 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.

2744-5. Using the driving support systems
■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 Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., fro m 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
■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.)
is installed.
●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
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’ 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 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 abnormally,
or objects, such as a wall, may not
be detected.
●A sensor is covered 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 attent ion to the follow-
ing 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.

■Detection range of the sen-
sorsApproximately 3.3 ft. (100
cm)
Approximately 4.9 ft. (150
cm)
Approximately 2.1 ft. (63 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos
e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Distance display
When an object is detected by a sensor, the approximate distanc e to
the object will be displayed on th e multi-information display, naviga-
tion system (if equipped) or multimedia system (if equipped) sc reen.
(As the distance to the object becomes short, the distance segm ents
may blink.)
The images may differ from that shown in the illustrations.

*: The distance segments will blink slowly.
Approximate distance to object: Less than 0.5 ft. (15 cm)
*: The distance segments will blink rapidly.
■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.
