detected is betw
een the vehicle
and a detected object

parking spaces next to your vehi-
cle

●The distance between the sensor
and approaching vehicle gets too
close
*: Depending on the conditions, detection of a vehicle and/or
object may occur.
■Situations in which the system
may not operate properly
The RCTA function may not detect
vehicles correctly in the following
situations:

due to a strong impact to the sen-
sor or its surrounding area
●When mud, snow, ice, a sticker,
etc.,is covering the sensor or sur-
rounding area on the position

●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:

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

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
displayed
PKSB OFF indicator: Not illumi-
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.)

described in the following sec-
tion.
“Gain” setting on trailer brake
controller should be set for a
specific towing condition. “Gain”
setting should be adjusted each
time the vehicle load, trailer
load, road conditions, or
weather changes. Setting the
“gain” value to 0 will disable the
trailer brake controller output. 1
Make sure the trailer brakes
are in good working condition
and functioning normally. See
trailer dealer if necessary.
2 Hook up the trailer and make
proper electrical connections.
3 Select the correct type of
trailer brakes that are
equipped on the trailer by
using the multi-information
display.
4 Drive vehicle with trailer
attached on a level road sur-
face similar to towing condi-
tion and in traffic-free
environment. Driving speed
should be approximately 20 -
25 mph [35 - 40 km/h].
5 Using the “GAIN” (+/-) selec-
tion buttons, set a starting
“gain” of 5.0.
6 While driving 20 - 25 mph [35

8 For confirmation, repeat
steps 6 and 7 until desired
“gain” setting is reached (just
below point of trailer wheel
lock-up).
■When setting the “gain”
Wheel lock-up occurs when the
trailer wheel squeals or tire smoke
occurs. Trailer wheels may not lock-
up while driving heavily loaded
trailer. During this case, adjust the
Trailer “gain” to the highest allow-
able setting for the towing condition.
■When disconnecting and recon-
necting 12-volt battery termi-
nals
The “gain” setting data will be reset.
■Trailer Sway Control Function
Helps suppress trailer sway at an
early stage by using the trailer brake
control system to operate the trailer
brakes.
■If the Trailer brake warning light
comes on
Indicates a malfunction in the Trailer
brake control system or Trailer con-
nector circuit.
Have the vehicle inspected by your
Toyota dealer immediately.
WARNING
■Trailer brake type setting
It is the responsibility of the driver
to make sure the trailer brakes
are functioning normally and
adjusted appropriately. Failure to
check and maintain trailer brakes
may result in loss of vehicle con-
trol, crash, or serious injury.
Trailer brake control system will
work with most electric and elec-
tric-overhydraulic trailer braking
systems up to 3 axles (24A output
to trailer brakes). Please be sure
to test compatibility with the sys-
tem at low speeds and in a safe
area. If a warning message
appears in the multi-information
display ( P.511), have the vehi-
cle inspected by your Toyota
dealer immediately. Some elec-
tric-over-hydraulic trailer brakes
will take some minimum output to
activate. Trailer brake control sys-
tem will not work with trailer
hydraulic surge brakes.
