*: If equipped
BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that has 2 functions:
 The BSM (Blind Spot Monitor)
function
Assists the driver in making a
decision when changing lanes
 The RCTA (Rear Crossing
Traffic Alert) function
Assists the driver when backing
up
These functions use the same
sensors.
WARNING
■Cautions regarding the use of the BSM function
The driver is solely responsible for safe driving. Always drive safely, tak-ing care to observe your surround-
ings. The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rapidly from behind into a blind spot.
Do not overly rely on the BSM func- tion. As the function cannot judge if it is safe to change lanes, over reliance
could lead to an accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of safety is necessary.

■Outside rear view mirror indicators visibility
In strong sunlight, the outside rear view mirror indicator may be difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to
hear over loud noises such as high audio volume.
■When “Blind Spot Monitor Unavail-able” or “RCTA Unavailable” is
shown on the multi-information display
The sensor voltage has become abnor-
mal, or water, snow, mud, etc., may be built up in the vicinity of the sensor area of the rear bumper. ( P.388)
Removing the water, snow, mud, etc., from the vicinity of the sensor area should return it to normal.
Also, the sensor may not function nor- mally when used in extremely hot or cold weather.
■When “Blind Spot Monitor Malfunc-
tion Visit Your Dealer” or “RCTA Malfunction Visit Your Dealer” is shown on the multi-information
display
There may be a sensor malfunction or misaligned. Have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
■Customization
Some functions can be customized. ( P.206, 217)
WARNING
■To ensure the system can oper- ate properly
Blind Spot Monitor sensors are installed inside the left and right sides of the rear bumper respectively.
Observe the following to ensure the Blind Spot Monitor can function cor-rectly.
●Keep the sensors and the sur-rounding areas on the rear bumper
clean at all times. If a sensor or its surrounding area on the rear bumper is dirty or cov-
ered with snow, the Blind Spot Monitor may not operate and a warning message ( P.388) will be
displayed. In this situation, clear off the dirt or snow and drive the vehi-cle with the operation conditions of
the BSM function ( P.390) satis- fied for approximately 10 minutes. If the warning message does not dis-
appear, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.

■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-
