Vehicle that may be detected
The system may detect that a vehi-
cle is passing in front of your
vehicle. Always be sure to check the
surroundings with your eyes when
reversing the vehicle.
■Operating conditions
The BSD/RCTA will operate
when all of the following condi-
tions are met.
The engine switch is in ON.
The BSD/RCTA warning light
and BSD/RCTA OFF indicator
are turned off.
The vehicle is driven at
speeds above 7 mph (12
km/h) (except when revers-
ing).
The shift lever is in R. (RCTA
only)
The BSD/RCTA will not operate
in the following situations.
The BSD/RCTA OFF indicator
appears.
WARNING
An approaching vehicle may
not be detected because the
detection range is limited by the
parked vehicle . Always be
sure to check the surroundings
with your eyes when reversing the
vehicle.

Driving
The vehicle speed is below 6
mph (10 km/h) even when the
BSD/RCTA OFF indicator
does not appear (except
when reversing).
●In the following cases, the
BSD/RCTA will stop operating and
the BSD/RCTA warning light will
appear.
• When a malfunction occurs in the system, including the BSD/RCTA
approach indicator
●If the BSD/RCTA warning light
appears, exercise proper caution.
( P.238)
●In the following cases, the
BSD/RCTA will temporarily stop
operating (or may stop operating)
and the BSD/RCTA OFF indicator
will appear.
• When the radar sensor becomes significantly misaligned (If the ori-
entation of the r adar sensor is
shifted for any reason, readjust-
ment is required. Have the sensor
adjusted at a Toyota dealer.)
• When a large amount of snow or ice sticks to the rear bumper sur-
face around the radar sensors
• When the vehicle is driven on a snow-covered road or in an envi-
ronment in which there are no
objects around (such as in a des-
ert) for a prolonged period of time
• When the temperature around the
radar sensors increases exces-
sively due to long driving on uphill
grades in the summer, etc.
• When the temperature around the radar sensors becomes extremely
low
• When the vehicle battery voltage lowers
• When the vehicle voltage exceeds
the battery voltage rating
●The BSD/RCTA will resume oper-
ation once these conditions are
corrected, and the BSD/RCTA
OFF indicator will disappear. How-
ever, if the BSD/RCTA OFF indi- cator appears for a prolonged
period of time, have the system
inspected at a Toyota dealer as
soon as possible.
●The detectability o
f the radar sen-
sors is restricted. The BSD/RCTA
detection may be impaired and
the system may not operate prop-
erly under the following condi-
tions.
• When the rear bumper around the
radar sensors is distorted
• When ice, snow or mud adheres to the rear bumper surface around
the radar sensors
• When stickers, etc . are affixed on
the areas of the radar sensors on
the rear bumper
• During adverse weather condi- tions such as ra in, snow or fog
• When driving on wet roads such as snow-covered roads and
through puddles
●The radar sensors may not detect
or may have difficulty detecting
the following vehicles and objects.
• Small motorcycles, bicycles, pedestrians, stationary objects on
the road or ro ad side, etc.
• Vehicles with body shapes that the radar may not reflect (vehicles
with lower body height such as a
trailer with no cargo and sports
cars)
• Vehicles that are not approaching
your vehicle even though they are
in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when revers-
ing) (The system determines the
presence of approaching vehicles
based on data detected by the
radar sensors.)
• Vehicles traveling at significantly
different speeds
• Vehicles driving in parallel at almost the same speed as your
vehicle for a prolonged time
• Oncoming vehicles
• Vehicles in a lane beyond the neighboring lane
• Vehicles travelling at a signifi- cantly lower speed that you are

●On a road with extremely narrow
lanes, the system may detect
vehicles driving in a lane next to
the neighboring lane.
While the BSD/RCTA is active,
the following item(s) will operate
to alert the driver:
The BSD/RCTA approach
indicator (when there are
vehicles in the neighboring
lanes).
The BSD/RCTA approach
indicator and warning buzzer
(when a vehicle is approach-
ing from the left or right side
while your vehicle is revers-

■BSD/RCTA approach indi-
cator
It is mounted on each side of the
outside mirrors.
The indicator will illuminate
when a vehicle approaching
from behind is detected.
The indicator will flash to warn
the driver of dangers under the
following conditions.

nating, if the turn signal lever

●You may have difficulty seeing the
BSD/RCTA approach indicator
under the following conditions.
• When sunlight shi nes directly on it
• When the headlight beams from a vehicle traveling behind shines
directly on it
●While the illumination brightness
control dial is in the fully upward
position, even if the headlights are
turned on, the brightness of the
BSD/RCTA approach indicator will
not be reduced. For details about

To turn the BSD/RCTA system
on and off, operate the

( P.400) or multimedia system
screen (Refer to “MULTIMEDIA
OWNER'S MANUAL”).
When the BSD/RCTA system is
turned OFF, the BSD/RCTA
OFF indicator on the multi-infor-
mation display will illuminate.
●In the following cases, turn off the
BSD/RCTA system. The system
may not operate properly due to
blocked radar waves.
• When towing the vehicle
• When a bicycle carrier or other item is fitted to the rear of the vehi-
cle
• When using a chassis dynamome-
ter or free rolle r device, etc.
• When running the engine and making the wheels rotate while lift-
ing up the vehicle
●If the engine switch is turned to
OFF, the last known status of the
system is maintained. For exam-
ple, if the engine switch is turned
to OFF with the BSD/RCTA deac-
tivated, the BSD/RCTA remains
deactivated the next time the
engine switch is turned to ON.
The radar sensors, one on each
side of the vehicle, are mounted
inside the rear bumper.
