●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 you r 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 syste m 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 diffi cult 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 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.
■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. Part icular 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 froz en. (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.

■Detection range of the sen-
sorsApproximately 3.3 ft. (100
cm)
Approximately 4.9 ft. (150
cm)
Approximately 2.0 ft. (60 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.
■Multi-information display, head-up display (if equipped) and
audio system screen
When an object is detected by a sensor, the approximate distanc e to
the object will be displayed on th e multi-information display, audio
system screen, and head-up display (if equipped). (As the dista nce
to the object becomes short, the distance segments may blink.)

■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. ( P.289)

WARNING
■Cautions regarding the use of
the function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
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.
NOTICE
■Before using the RCTA func-
tion
Do not place objects near the sen-
sors.

3986-1. Maintenance and care
Remove dirt and dust using a
vacuum cleaner.
 Wipe off any excess dirt and
dust with a soft cloth damp-
ened with diluted detergent.
Use a diluted water solution of
approximately 5% neutral wool
detergent.
Wring out any excess water
from the cloth and thoroughly
wipe off all remaining traces
of detergent.
 Wipe the surface with a dry,
soft cloth to remove any
remaining moisture. Allow the
leather to dry in a shaded and
ventilated area.
■Caring for leather areas
Toyota recommends cleaning the
interior of the vehicle at least twice a
year tomaintain the quality of the
vehicle’s interior.
NOTICE
●Do not use polish wax or polish
cleaner. The instrument panel’s
or other interior part’s painted
surface may be damaged.
■Preventing damage to leather
surfaces
Observe the following precautions
to avoid damage to and deteriora-
tion of leather surfaces:
●Remove any dust or dirt from
leather surfaces immediately.
●Do not expose the vehicle to
direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.
●Do not place items made of
vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■Water on the floor
Do not wash the vehicle floor with
water.
Vehicle systems such as the
audio system may be damaged if
water comes into contact with
electrical components such as the
audio system above or under the
floor of the vehicle. Water may
also cause the body to rust.
■When cleaning the inside of
the windshield
Do not allow glass cleaner to con-
tact the lens. Also, do not touch
the lens. (
P.229)
■Cleaning the inside of the rear
window
●Do not use glass cleaner to
clean the rear window, as this
may cause damage to the rear
window defogger heater wires
or antenna. Use a cloth damp-
ened with lukewarm water to
gently wipe the window clean.
Wipe the window in strokes run-
ning parallel to the heater wires
or antenna.
●Be careful not to scratch or
damage the heater wires or
antenna.
