■Outside rear view mirror indica-
tors visibility
In strong sunlight, the outside rear
view mirror indicato r 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
Unavailable” or “Rear Cross
Traffic Alert Unavailable” is
shown on the multi-information
display
The sensor voltage has become
abnormal, or water, snow, mud,
etc., may be built up in the vicinity of
the sensor area of the rear bumper.
(  P.380)
Removing the water, snow, mud,
etc., from the vicinity of the sensor
area should retur n it to normal.
Also, the sensor may not function
normally when used in extremely
hot or cold weather.
■When “Blind Spot Monitor Mal-
function Visit Your Dealer” or
“Rear Cross Traffic Alert Mal-
function Visit Your Dealer” is
shown on the multi-information
display
There may be a sensor malfunction
or misaligned. Have the vehicle
inspected at a Toyota dealer.
■Customization
Some functions can be customized.
(  P.191, 203)
WARNING
■To ensure the system can
operate properly
Blind Spot Monitor sensors are
installed inside t he left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the Blind Spot Monitor can
function correctly.
●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 covered with snow, the Blind
Spot Monitor may not operate
and a warning message
(  P.380) will be displayed. In
this situation, clear off the dirt or
snow and drive the vehicle with
the operation conditions of the
BSM function ( P.382) satis-
fied for approximately 10 min-
utes. If the warning message
does not disappear, have the
vehicle inspected by your
Toyota dealer.
●Do not subject a sensor or its
surrounding area on the rear
bumper to a strong impact.
If a sensor is moved even
slightly off position, the system
may malfunction and vehicles
may not be detected correctly.
In the following si tuations, have
your vehicle inspected by your
Toyota dealer.
• A sensor or its surrounding area is subject to a strong impact.

■Vehicles that can be
detected by the Blind Spot
Monitor
The BSM function uses radar
sensors to detect the following
vehicles traveling in adjacent
lanes and advises the driver of
the presence of such vehicles
via the indicators on the outside
rear view mirrors. Vehicles that are traveling in
areas that are not visible
using the outside rear view
mirrors (the blind spots)
Vehicles that are approach-
ing rapidly from behind in
areas that are not visible
using the outside rear view
mirrors (the blind spots)
■The BSM function detection
areas
The areas that vehicles can be
detected in are outlined below.
WARNING

3825-5. Using the driving support systems
The range of each detection area
is:
Approximately 1.6 ft. (0.5 m)
to 11.5 ft. (3.5 m) from either
side of the vehicle
The area between the side of the
vehicle and 1.6 ft. (0.5 m) from the
side of the vehicle cannot be
detected.
Approximately 3.3 ft. (1 m)
forward of the rear bumper
Approximately 9.8 ft. (3 m)
from the rear bumper
Approximately 9.8 ft. (3 m) to
197 ft. (60 m) from the rear
bumper
The greater the difference in speed
between your vehicle and the
detected vehicle is, the farther
away the vehicle will be detected,
causing the outside rear view mirror
indicator to illuminate or flash.
