■Conditions under which the system
may not function correctly
●The BSM function may not detect
vehicles correctly in the following situ-
ations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc.,
is covering the sensor or surrounding
area on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or
fog
• When multiple vehicles are approach-
ing with only a small gap between
each vehicle
• When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and
the vehicle that enters the detection
area
• When the difference in speed
between your vehicle and another
vehicle is changing
• When a vehicle enters a detection
area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a
vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.
• When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
• When vehicle lanes are wide, or when
driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle
• When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
• When there is a significant difference
in height between your vehicle and
the vehicle that enters the detection
area
• Immediately after the BSM func-
tion/RCTA function are turned on
• When towing a trailer
●Instances of the BSM function unnec-
essarily detecting a vehicle and/or
object may increase in the following
situations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When the distance between your vehi-
cle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecu-
tive 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 vehicle traveling in a lane other
than the adjacent lanes enters the
detection area
• When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning
• When the distance between your vehi-
cle and a following vehicle is short
• When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
• When the vehicle throws up water or
snow behind.
■Operation of the RCTA func-
tion
The RCTA function uses radar sen-
sors to detect vehicles approaching
from the right or left at the rear of
the vehicle and alerts the driver of
the presence of such vehicles by
flashing the outside rear view mirror
indicators and sounding a buzzer.
The Rear Crossing Traffic
Alert function

monitor (if equipped) is displayed
When the panoramic view moni-
tor (if equipped) is displayed
■The RCTA function detection
areas
The areas that vehicles can be
detected in are outlined below.
The buzzer can alert the driver of faster
vehicles approaching from farther
away.

essarily detecting a vehicle and/or
object may increase in the following situ-
ations:

Toyota parking assist-
sensor
The distance from your vehicle
to objects, such as a wall,
when parallel parking or
maneuvering into a garage is
measured by the sensors and
communicated via the multi-
information display or Multi-
media Display and a buzzer.
Always check the surrounding
area when using this system.

To re-enable the system, select on
the multi-information display, select
and turn it on.
If the system is disabled, it will remain
off even if the power switch is turned to
ON after the power switch has been
turned off.
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” is displayed on the multi-information
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 normal.
Also, due to ice forming on a sensor at
low temperatures, a warning message
WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recog- nition accuracy and control perfor-mance that this system can provide,
do not overly rely on this system. The driver is always responsible for pay-ing attention to the vehicle’s sur-
roundings and driving safely.
■To ensure the system can oper-
ate properly
Observe the following precautions. Failing to do so may result in the vehi-
cle being unable to be driven safely and possibly cause an accident.
●Do not damage the sensors, and always keep them clean.
●Do not attach a sticker or install an electronic component, such as a backlit license plate (especially fluo-
rescent type), fog lights, fender pole or wireless antenna near a radar sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer. If the front or rear bumper needs to be removed/installed or replaced,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not modify, disassemble or paint the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the
function as it may operate even though there is no possibility of a colli-sion.
●Failing to observe the warnings above.
●A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■Notes when washing the vehicle
Do not apply intensive bursts of water
or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not
spray the sensors directly, as doing so may cause a sensor to malfunc-tion.
●When using steam to clean the vehicle, do not direct steam too
close to the sensors as doing so may cause a sensor to malfunction.

3985-5. Using the driving support systems
may be displayed or the sensor may not
be able to detect an object. Once the ice
melts, the system will return to normal.
If a warning message is displayed even
if the sensor is clean, there may be a
sensor malfunction. Have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer.
■If “Parking Assist Unavailable” is
displayed on the multi-information
display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
■Sensor detection information
●The sensor’s detection areas are lim-
ited to the areas around the vehicle’s
front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection dis-
tance may shorten, or detection may
be impossible.
• Detection may be impossible if static
objects draw too close to the sensor.
• There will be a short delay between
static object detection and display
(warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come within 25 cm (9.8 in.)
before the display is shown and the
warning buzzer 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.
• It may be difficult to hear the sound of this system due to the buzzers of
other systems.
■Objects which the system may not
properly detect
The shape of the object may prevent the
sensor from detecting 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 pro-
jecting outwards in the direction of
your vehicle
People may not be detected if they are
wearing certain types of clothing.
■Situations in which the system may
not operate properly
Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect
objects. Particular 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
displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
