■Situations in which the system
may not operate properly
The RCTA function may not detect
vehicles correctly in the following
situations:

etc.,is covering the sensor or sur-
rounding area on the position
above the rear bumper

during bad weather, such as
heavy rain, snow, or fog
●When multiple vehicles are
approaching with only a small gap
between each vehicle
●When a vehicle is approaching at
high speed

obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additi onal trim strip,
etc.), bicycle carrier, or snow plow

a sharp change in grade
●When backing out of a sharp
angle parking spot
●Immediately after the RCTA func-
tion is turned on

tem is started with the RCTA func-
tion on
●When there is a significant differ-
ence in height between your vehi-
cle and the vehicle that enters the
detection area
●When a sensor or the area around
a sensor is extremely hot or cold
●If the suspension has been modi-
fied or tires of a size other than
specified are installed
●If the front of the v ehicle is raised
or lowered due to the carried load
●When turning while backing up

●When a vehicle turns into the
detection area
■Situations in which the system
may operate even if there is no
possibility of a collision
Instances of the RCTA function
unnecessary detec ting a vehicle
and/or object may increase in the
following situations:
●When the parking space faces a
street and vehicles are being
driven on the street
●When the distanc e between your
vehicle and metal objects, such as
a guardrail, wall, sigh, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
●When a vehicle passes by the
side of your vehicle
●When a detected vehicle turns
while approaching the vehicle
●When there are spinning objects
near your vehicle such as the fan
of an air conditioning unit
●When water is splashed or
sprayed toward the rear bumper,
such as from a sprinkler
●Moving objects (f lags, exhaust
fumes, large rain droplets or
snowflakes, rain water on the road
surface, etc.)
●When the distance between your
vehicle and a guardrail, wall, etc.,
that enters the detection area is
short

PKSB (Parking Sup-
port Brake)
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility of
a collision with a detected
object or pedestrian is
extremely high, the brakes
are automatically applied to
help avoid the collision or
help reduce the impact of
the collision.

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no poss ibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used

Driving
Press the switch to enable/dis-
able the parking support brake.
All of the Parking Support Brake
functions (static objects and
rear-crossing vehicles) are
enabled/disabled simultane-
ously.
When the Parking Support Brake is
disabled, the PKSB OFF indicator
(  P.89) illuminates.
To enable the system, press the
switch again. If disabled using this
method, the syst em will not be re- enabled by turning the power
switch off and then to ON.
■When towing a trailer
When the 7-pin connector is con-
nected and Auto Trailer Detection
(ATD) ( P.270) is activated, the
function automatically turns off.
■When “4L” mode selected (4WD
models)
The parking support brake is auto-
matically disabled.
If the hybrid system output restric-
tion control or brake control oper-
ates, a buzzer will sound and a
message will be displayed on the
multi-information display and head-
up display (if equipped), multimedia
display, to alert the driver.
Depending on the situation, hybrid
system output restriction control will
operate to either limit acceleration
or restrict output as much as possi-
ble.
 Hybrid system output restric-
tion control is operating
(acceleration restriction)
Acceleration greater than a certain
amount is restric ted by the system.
Multi-information display: “Object
Detected Acceleration Reduced”
Multimedia display and head-up
display (if equipped): No warning

nated
NOTICE
■If “PKSB Unavailable” is dis-
played on the multi-informa-
tion display and the PKSB
OFF indicator is on
If this message is displayed
immediately after the power
switch is changed to ON, operate
the vehicle carefully, paying atten-
tion to your surroundings. It may
be necessary to drive the vehicle
for a certain amount of time
before the system returns to nor-
mal. (If the system does not return
to normal after driving for a while,
clean the sensors and their sur-
rounding area on the bumpers.)
