■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.296)

WARNING
■Cautions regarding the use of
the function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings.
The RCTA functi on is only a sup-
plementary function which alerts
the driver tha t 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.

press .
Each time the switch is pressed,
the volume lev el will change
between 1, 2, and 3.
■Muting a buzzer temporarily
A mute button will be displayed
on the multi-information display
when an object is detected. To
mute the buzzer, press .
Mute will be canceled automati-
cally 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 power switch is
turned off.
■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 a nd alerts
the driver of the presence of such vehicles by flashing the out side
rear view mirror indicators and sounding a buzzer.

■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 opera-
tional when
The RCTA function operates when
all of the followin g conditions are
met:
●The power switch is in ON.
●The RCTA function is on.
●The shift lever is in R.
●The vehicle spe ed is less than
approximately 5 mph (8 km/h).
●The approaching vehicle speed is
between approximately 5 mph (8
km/h) and 18 mph (28 km/h).
■Conditions under which the
RCTA function will not detect a
vehicle
The RCTA function is not designed
to detect the follo wing types of vehi-
cles 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

: Depending on the conditions, detection of a vehicle and/or
object may occur.
■Conditions under which the
RCTA function may not function
correctly
●The RCTA function may not detect
vehicles correctly in the following
situations:
• When a sensor is misaligned due
to a strong impact to the sensor or
its surrounding area
• When mud, snow, ice, a sticker, etc. is covering a sensor or its sur-
rounding 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
approaching with only a small gap
between each vehicle
• If a vehicle is approaching the rear
of your vehicle rapidly
• When a towing eyelet is installed to the rear of the vehicle.
• When backing up on a slope with
a sharp change in grade • When backing out of a shallow
angle parking spot
• Immediately after the RCTA func- tion is turned on
• Immediately after the hybrid sys- tem is started with the RCTA func-
tion on
• When the sensors cannot detect a vehicle due to obstructions
●Instances of the RCTA function
unnecessarily detecting a vehicle
and/or object may increase in the
following situations:
• When a vehicle passes by the side of your vehicle
• When the parking space faces a street and vehicles are being
driven on the street
