■The Parking Support Brake
function (rear-crossing vehi-
cles) will operate when
The function will operate when the
PKSB OFF indicato r is not illumi-
nated or flashing ( P.77, 79) and
all of the followin g conditions are
met:
●Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 9 mph (15 km/h) or less.
• Vehicles are approaching from the
right or left at the rear of the vehi-
cle at a traveling speed of more
than approximately 5 mph (8
km/h)
• The shift lever is in R.
• The Parking Support Brake deter- mines that a stronger than normal
brake operation is necessary to
avoid a collision with an approach-
ing vehicle.
●Brake control
• Engine output restri ction control is operating
• The Parking Support Brake deter- mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.
■The Parking Support Brake
function (rear-crossing vehi-
cles) will stop operating when
The function will stop operating if
any of the following conditions are
met:
●Engine output restriction control
• The Parking Support Brake is dis- abled.
• The collision becomes avoidable with normal brake operation.
• A vehicle is no longer approaching
from the right or le ft at the rear of
the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed
after the vehicle is stopped by
brake control.
• A vehicle is no longer approaching
from the right or le ft at the rear of
the vehicle.
■Detection area of the Parking
Support Brake function (rear-
crossing vehicles)
The detection area of the Parking
Support Brake function (rear-cross-
ing vehicles) differs from the detec-
tion area of the RCTA function
(  P.271). Therefore, even if the
RCTA function detects a vehicle
and provides an alert, the Parking
Support Brake function (rear-cross-
ing vehicles) may not start operat-
ing.
■Conditions under which the
Parking Support Brake func-
tion (rear-crossing vehicles)
will not detect a vehicle

WARNING
●Do not modify, disassemble or
paint the sensors.
●Do not replace a rear radar sen-
sor with a part o ther than a gen-
uine part.
●Do not damage the rear radar
sensors, and always keep the
radar sensors and their sur-
rounding area on the bumper
clean.
●If the area around a rear radar
sensor is subjected to an
impact, the system may not
operate properly due to a sen-
sor malfunction. Have the vehi-
cle inspected by your Toyota
dealer.
●Observe the rear radar sensor
handling precautions. ( P.267)

2944-5. Using the driving support systems
(rear-crossing vehicles) 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
●Vehicles which suddenly acceler-
ate or decelerate near your vehi-
cle
●Guardrails, walls, signs, parked
vehicles and similar stationary
objects
*
●Small motorcycles, bicycles,
pedestrians, etc.*
●Vehicles moving away from your
vehicle
●Vehicles approaching from the
parking spaces next to your vehi-
cle
*
●Objects which are extremely close
to a radar sensor*
●Vehicles which are approaching
from the right or left at the rear of
the vehicle at a traveling speed of
less than approximately 5 mph (8
km/h)
●Vehicles which are approaching
from the right or left at the rear of
the vehicle at a traveling speed of
more than approximately 15 mph
(24 km/h)
*: Depending on the conditions,
detection of a vehicle and/or
object may occur.
■Situations in which the system
may operate even though there
is no possibility of a collision
In some situations such as the fol-
lowing, the Parking Support Brake
function (rear-cro ssing vehicles)
may operate even t hough there is
no possibility of a collision.
●When the parking space faces a
street and vehicles are being
driven on the street
●When a detected vehicle turns
while approaching the vehicle
●When a vehicle passes by the
side of your vehicle
●When the distance between your
vehicle and metal objects, such as
a guardrail, wall, sign, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short

●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
■Situations in which the Parking
Support Brake function (rear-
crossing vehicles) may not
operate properly
In some situations, such as the fol-
lowing, the radar sensors may not
detect an object and this function
may not operate properly
●Stationary objects
●When a sensor or the area around
a sensor is extremely hot or cold
●If the rear bumper is covered with
ice, snow, dirt, etc.
●When it is raining heavily or water
strikes the vehicle
●When the detecti on area of a
radar sensor is obstructed by an
adjacent vehicle
●If the vehicle is s ignificantly tilted
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle carrier, or snow plow
●If the suspension has been modi-
fied 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
●If a sticker or an electronic compo-
nent, such as a backlit license
plate (especially fluorescent type),
fog lights, fender pole or wireless antenna is installed near a radar
sensor
●If the orientation of a radar sensor
has been changed
●When multiple vehicles are
approaching with only a small gap
between each vehicle
●If a vehicle is approaching the rear
of your vehicle rapidly
●Situations in which the radar sen-
sor may not detect a vehicle
• When a vehicle approaches from
the right or left at the rear of the
