and rear side sensors)
The diagram shows the detection range
of the sensors. Note that the sensors
cannot detect objects that are

the side areas. ( P.305)
The range of the sensors may change
depending on the shape of the object,
etc.
■Multi-information display and head-up display (if equipped)
When an object is detected by a sens or, the approximate distance to the
object will be displayed on the multi- information display and head-up dis-
play (if equipped). (As the distance to the object becomes short, the dis-
tance segments may blink.)
The front side sensor displays and rear side sensor displays (if equipped)
are not shown until a scan of the side areas is completed.

Driving
When the vehicle comes within
approximately 30 cm (1.0 ft.) of
the object, the buzzer sounds
continuously.
 When 2 or more objects are
detected simultaneously, the
buzzer sounds for the nearest
object. If one or more objects
come within approximately 30
cm (1.0 ft.) of the vehicle, the
buzzer will repeat a long tone,
followed by fast beeps.
 Automatic buzzer mute function:
After a buzzer begins sounding,
if the distance between the vehi-
cle and the detected object does
not become shorter, the buzzer
will be muted automatically.
(However, if the distance
between the vehicle and object is
30 cm (1.0 ft.) or less, this func-
tion will not operate.)
■Adjusting the buzzer volume
The buzzer volume can be adjusted
on the multi-information display.
The volume of buzzers for the
Toyota parking assist-sensor and
RCTA function (if equipped) will be
adjusted simultaneously.
Use the meter control switches to
change settings. ( P.100)
1 Press or to select .
2 Press or to select
and then press and hold .
3 Select the volume and then
press .
Each time the switch is pressed, the
volume level will change between 1, 2,
and 3.
■Muting a buzzer
A mute button will be displayed on
the multi-information display when
an object is detected. To mute the
buzzer, press .
The buzzers for the Toyota parking
assist-sensor and RCTA function (if
equipped) will be muted simultane-
ously.
Mute will be canceled automatically
in the following situations:
 When the shift lever is changed.
 When the vehicle speed exceeds
a certain speed.
 When the operating function is
temporarily canceled.
 When the operating function is
disabled manually.
 When the engine switch is turned
off.

RCTA (Rear Crossing
Traffic Alert) function*
The RCTA function uses the
BSM rear side radar sensors
installed behind the rear
bumper. This function is
intended to assist the driver in
checking areas that are not
easily visible when backing up.

■Cautions regarding the use of the system
There is a limit to the degree of recog-
nition accuracy and control perfor- mance that this system can
provide,do not overly rely on this sys-
tem. The driver is always responsible for paying attention to the vehicle’s
surroundings and driving safely.

Driving■Outside rear view mirror indicator visibility
In strong sunlight, the outside rear view
mirror indicator may be difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear over loud noises, such as if the
audio system volume is high.
■When “RCTA Unavailable” is
shown on the multi-information display
Water, snow, mud, etc., may be
attached to the rear bumper around the sensors. ( P.300) Removing the water,
snow, mud, etc., from the attached to
the rear bumper around the sensors to normal.
Additionally, the function may not func-
tion normally when used in extremely hot or cold environments.
■Rear side radar sensors
 P. 3 0 0
■Operation of the RCTA function
The RCTA function uses rear side 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 indicators and sounding a buzzer.

■Cautions regarding the use of
the function
The driver is solely responsible for safe driving. Always drive safely, tak-
ing care to observe your
surroundings.
The RCTA function is only a supple-
mentary 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 conditions, the driver’s own visual
confirmation of safety is necessary.
Over reliance on this function may lead to an accident resulting death or
serious injury.

■RCTA function detection areas
The areas that vehicles can be detected in are outlined below.
The buzzer can alert the driver of
faster vehicles approaching from
farther away.
Example:
■The RCTA function is operational
when
The RCTA function operates when all of
the following conditions are met:
●The engine switch is in ON.
●The RCTA function is on.
●The shift lever is in R.
●The vehicle speed is approximately 15
km/h (9 mph) or less.
●The approaching vehicle speed is
between approximately 8 km/h (5
mph) and 56 km/h (34 mph).
■Adjusting the buzzer volume

■Conditions under which the system
will not detect a vehicle
The RCTA function is not designed to
detect the following types of vehicles
and/or objects:
●Vehicles approaching from directly
behind
●Vehicles backing up in a parking
space next to your vehicle
●Vehicles that the sensors cannot
detect due to obstructions
●Guardrails, walls, signs, parked vehi-
cles and similar stationary objects*
●Small motorcycles, bicycles, pedestri-
ans, etc.*
●Vehicles moving away from your vehi- cle
●Vehicles approaching from the park-
ing spaces next to your vehicle*
●The distance between the sensor and
approaching vehicle gets too close*: Depending on the conditions, detec-
tion of a vehicle and/or object may
occur.
■Situations in which the system may not operate properly
The RCTA function may not detect vehi-
cles correctly in the following situations:
●When the sensor is misaligned due to
a strong impact to the sensor or its surrounding area
●When mud, snow, ice, a sticker, etc.,
is covering the sensor or its surround- ing area on the rear bumper
●When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or
fog
●When multiple vehicles are approach-
ing with only a small gap between each vehicle
●When a vehicle is approaching at high speed
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or snow plow
●When backing up on a slope with a sharp change in grade
●When backing out of a sharp angle
parking spot
●When towing a trailer
●When there is a significant difference in height between your vehicle and
the vehicle that enters the detection
area
●When a sensor or the area around a
sensor is extremely hot or cold
