steep inclines, such as hills, dips in the
road, etc.
• When vehicle lanes are narrow, or when
driving on the edge of a lane, and a vehi-
cle traveling in a lane other than the adja-
cent lanes enters the detection area
• When driving on roads with sharp bends,

Intuitive parking assist (if
equipped)
Ultrasonic sensors are used to detect
static objects in the detection area
when driving at a low speed or backing
up. ( → P.257) ■
RCTA (Rear Cross Traffic Alert)
function (if equipped)
Radar sensors are used to detect
approaching vehicles in the detection
areas behind the vehicle when backing
up. ( → P.264) ■
RCD (Rear camera detection)
function (if equipped)
A rear camera sensor is used to detect
pedestrians in the detection area
behind the vehicle when backing up.
( → P.268)PKSA (Parking Support
Alert) *
The Parking Support Alert system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that a collision with a
detected object, such as a wall, or
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action.

Adjusting the buzzer volume
The buzzer volume can be adjusted on
the multi-information display. The vol-
ume of buzzers for the intuitive parking
assist, RCTA function and RCD func-
tion will be adjusted simultaneously.
Use the meter control switches to
change settings. ( → P.77)

3 Press or to select 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 or pedestrian is detected. To
mute the buzzer, press .
The buzzers for the intuitive parking
assist, RCTA function and RCD func-
tion will be muted simultaneously.
Mute will be canceled automatically in
the following situations:
 When the shift position is changed.
 When the operating function is tem-
porarily canceled.
 When the operating function is dis-
abled manually.
 When the engine switch is turned
off. *

Display
When the sensors detect an object,
such as a wall, a graphic is shown on
the multi-information display, head-up
display (if equipped) and Center Dis-
play depending on the position and dis-
tance to the object.
 Multi-information display and Setting the buzzer volume Intuitive parking assist *
The distance from your vehicle to
objects, such as a wall, when paral-
lel parking or maneuvering into a
garage is measured by the sensors
and communicated via the
multi-information display, head-up
display (if equipped), Center Dis-
play and a buzzer. Always check the
surrounding area when using this
system.

The buzzer volume can be adjusted on the
multi-information display. ( → P.257)■
If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-inform ation 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 nor-
mal.
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. ■
Sensor detectio n information●
The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection 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.■
Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular 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 dis-
played 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 sen-
sor 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 detectin g 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 project-
ing outwards in the direction of your vehi-
cle
People may not be de tected if they are
wearing certain types of clothing.

Buzzer operation and distance to
an object
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously: Approximately 1.0 ft. (30 cm)
 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 function:
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.257)Multi-information display *2

The areas that vehicles can be detected in are outlined below.
The buzzer can alert the driver of
faster vehicles approaching from far-
ther 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 IGNITION ON
mode.
●
The RCTA function is on.
●
The shift position is in R.
●
The vehicle speed is less than approxi- mately 5 mph (8 km/h). ●
The approaching vehicle speed is
between approximately 5 mph (8 km/h)
and 18 mph (28 km/h). ■
Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( → P.257)■
Conditions under which the RCTA func-
tion 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

If “Rear Camera Detection Unavailable
Remove the Dirt of Rear Camera” is dis-
played on the multi-information display
A rear camera lens ma y be dirty or covered
with snow or ice. In such cases, if it is
removed from the rear camera lens, the sys-
tem should return to normal. (It may be nec-
essary to drive the vehicle for some time
before the system returns to normal.) ■
If “Rear Camera Detection Unavail-
able” is displayed on the multi-informa-
tion display ●
If this message is di splayed after the bat-
tery has been disconnected and recon-
nected, fully turn the steering wheel to
the left and then the right on level ground.
●
If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the rear
camera lens.

Types of sensors WARNING
■
To ensure the Parking Support Brake
can operate properly
Observe the following precautions
regarding the sensors ( → P.278). Failure
to do so may cause a sensor to not oper-
ate properly, and may cause an accident. ●
Do not modify, disassemble or paint
the sensors.
●
Do not replace a sensor with a part
other than a genuine part.
●
Do not subject a sensor or its sur-
rounding area to a strong impact.
●
Do not damage the sensors, and
always keep them clean.
