present in the detection area in the fol-
lowing situations:
●A vehicle in an adjacent lane over-
takes your vehicle.
●You overtake a vehicle in an adjacent
lane slowly.

vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.

essarily detecting a vehicle and/or
object may increase in the following
situations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When the distance between your vehi-
cle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecu-

carrier) is installed to the rear of the
vehicle
• When the vehicle throws up water or
snow behind.
■Operation of the RCTA func-
tion
The RCTA function uses radar sen-
sors 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.Approaching vehicles

WARNING
■Toyota parking assist-sensor precautions
Observe the following precautions. Failing to do so may result in the vehi-cle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
●The sensors’ detection areas and
reaction times are limited. When moving forward or reversing, check the areas surrounding 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.

4165-5. Using the driving support systems
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” 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 system 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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
●The area directly under the bum-pers 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 colli-
sion.
●The vehicle is equipped with a com- mercial fender pole, wireless
antenna or fog lights.
●The front or rear bumper or a sen-
sor receives a strong impact.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
●When using an automatic car wash
■When using the Toyota parking assist-sensor
In the following situations, the system
may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●The Toyota parking assist-sensor operation display flashes or shows continuously, and a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display flashes or is displayed continuously and a buzzer does not sound, except when the mute func-
tion has been turned on.
■Notes when washing the vehicle
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 malfunc-
tion.
●When using steam to clean the
vehicle, do not direct steam too close to the sensors as doing so may cause a sensor to malfunction.

■If “Parking Assist Unavailable” is
displayed on the multi-information
display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
■Sensor detection information
●The sensor’s detection areas are lim-
ited 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 dis-
tance 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 25 cm (9.8 in.)
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 func-
tion may not function correctly
Certain vehicle conditions and the sur-
rounding 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 sensor.
(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 display 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 vehicles, or other
loud noises producing 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 properly
detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of
your vehicle

4185-5. Using the driving support systems
People may not be detected if they are
wearing certain types of clothing.
■Detection range of the sensorsApproximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely close 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 distance to the
object will be displayed on the multi-information display, navigation system
(if equipped) or multimedia system (if equipped) screen. (As the distance to
the object becomes short, the distance segments may blink.)
The images may differ from that shown in the illustrations.
Approximate distance to object
• Front center sensor: 100 cm (3.3 ft.) to 60 cm (2.0 ft.)

Approximate distance to object: Less than 15 cm (0.5 ft.)

■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sensors
are operating.
The buzzer beeps faster as the
vehicle approaches an object.
When the vehicle comes within
approximately 30 cm (1.0 ft.) of the object, the buzzer sounds
continuously
When 2 or more sensors simulta-
neously detect a static object,
the buzzer sounds for the near-
est object.
Even when the sensors are oper-
ating, the buzzer will be muted in
