Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(
P.287) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by your Toyota dealer.
■
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., 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 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 following situations may occur
during use.
• The sensor's detection areas are
limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the
object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a
sensor, it may not be detected.
• 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 detec-
tion 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.
■
Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention 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.
■
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, water drops 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 dis-
play may be displayed abnormally,
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).
●
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 carrier, or snow plow.
●
If the front of the vehicle 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 a tire chains, compact
spare tire or an emergency tire
puncture repair kit is 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.)

■
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
1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.
When 2 or more objects are
detected simultaneously, the
buzzer sounds for the nearest
object. If one or more objects
come within approximately
1.0 ft. (30 cm) of the vehicle,
the buzzer will repeat a long
tone, followed by fast beeps.
Automatic buzzer mute func-
tion: After a buzzer begins
sounding, if the distance
between the vehicle and the
detected object does not
become shorter, the buzzer
will be muted automatically.
(However, if the distance
between the vehicle and
object is 1.0 ft. (30 cm) or
less, this function will not
operate.)
The buzzer sounds volume can
be adjusted. (

Cautions regarding the use of
the function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-

The RCTA function is only a sup-
plementary function which alerts
the driver that a vehicle is
approaching from the right or left
at the rear of the vehicle. As the
RCTA function may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
Over reliance on this function may
lead to an accident resulting
death or serious injury.

The Parking Support Brake
system consists of the fol-

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 col-
lision.
