●Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the carried load
• If the orientation of a sensor has been changed due t o a collision or
other impact
■Situations in which the Parking
Support Brake function (static
objects) may not operate prop-
erly
In some situations, such as the fol-
lowing, this function may not oper-
ate properly.
●Weather
• When a sensor or the area around a sensor is extremely hot or cold
• When strong winds are blowing
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the
system will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather such as fog, snow or a sandstorm
• A sensor is frozen. (Thawing the
area will resolve this problem.)
●Vehicle surroundings
• When an object that cannot be detected is betw een the vehicle
and a detected object • If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle
• The vehicle is approaching a tall or curved curb.
• On an extremely bumpy road, on
an incline, on gravel, or on grass.
• The objects draw too close to the sensor.
●Other sonic waves sources
• When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
• 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 sensor
●Changes in the vehicle
• If the vehicle is significantly tilted
• If the front of the v ehicle is raised
or lowered due to the carried load
• If the orientation of a sensor has
been changed due to a collision or
other impact
• 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
• If the suspension has been modi- fied or tires of a size other than
specified are installed
• If paint or a stic ker is applied to
the sensor

2924-5. Using the driving support systems
*: If equipped
This function will operate in situations such as the following if a vehi-
cle is detected in the traveling direction of the vehicle.
■When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late
 P.267
Parking Support Brake function (rear-crossing
vehicles)*
If a rear radar sensor detects a vehicle approaching from the
right or left at the rear of the vehicle and the system deter-
mines that the possibility of a collision is high, this functio n
will perform brake control to reduce the likelihood of an
impact with the approaching vehicle.
Examples of function operation
Types of sensorsWARNING
■To ensure the Parking Sup-
port Brake (rear-crossing
vehicles) can operate prop-
erly
Observe the following precautions
regarding the rear radar sensors
(  P.267). Failure to do so may
cause a sensor t o not operate
properly, and may cause an acci-
dent.

■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

■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
