Limitations of the detectability
of RCTA
Since the detectability of RCTA
is limited, the RCTA may not
operate properly in angled park-
ing.

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.

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.237)
●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

trying to overtake
●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-
ing)
■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.
While the indicator is illumi-
nating, if the turn signal lever
is operated toward the side in
which this indicator turned on
When reversing the vehicle
while the system detects a
vehicle approaching from either side
BSD/RCTA approach indica-
tor
BSD/RCTA approach indica-
tor dimming function
When the headlights are turned
on, the brightness of the
BSD/RCTA approach indicator
will be reduced.
●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
the illumination bri ghtness control
dial, refer to P.91.
■BSD/RCTA approach warn-
ing buzzer (only when
reversing)
A warning buzzer sounds along
with flashing of the BSD/RCTA
approach indicator to warn the
driver of dangers. The setting of
the warning buzzer volume can

■Safety tips regarding the
BSD/RCTA approach indi-
cator/warning buzzer
In the following cases, opera-
tion of the BSD/RCTA
approach indicator and the
warning buzzer may be
delayed or the system may
fail to issue these warnings.
• When a vehicle moves to the
neighboring lane from a lane next
to the neighboring lane
• When driving on a steep incline or on repeated sharp uphill and
downhill grades
• When going beyond a pass
• When both your vehicle and a vehicle driving on a neighboring
lane are driving o n the far side of
each lane.
• When several narrowly-spaced vehicles are approaching in a row
• In low radius bends (tight bends or when making turns at an inter-
section)
• When there is a difference in height between your lane and the
neighboring lane
• Immediately after the BSD/RCTA is activated by touching
“BSD/RCTA”
• Immediately after the shift lever is shifted to R
• When extremely heavy cargo is loaded in the trunk
During reversing, operation of the BSD/RCTA approach indi-
cator and the warning buzzer
may be delayed or the system
may fail to issue these warn-
ings under the following con-
ditions.
• When backing out of an angled
parking space
• When a large-sized vehicle is parked next to your vehicle (That
vehicle prevents the propagation
of radar waves.)
• When reversing on sloped roads
• When reversing at a high speed
The BSD/RCTA approach
indicator may illuminate when
driving close to solid objects
on the road or road side (such
as guardrails, tunnels and
sidewalls).
When turning at an intersec-
tion in urban areas, or a multi-
lane intersection, the
BSD/RCTA approach indica-
tor may flash.
If a building or a wall exists in
the reversing direction, the
BSD/RCTA approach indica-
tor may flash and the warning
buzzer may sound.

Driving
In the following cases, the
system may detect a vehicle
driving two lanes away from
your vehicle.
• When your vehicle drives on the
near side of its l ane from the cor-
responding vehicle
• When the vehicle driving two lanes away drives on the near
side of its lane fr om your vehicle
■System temporary stops
This display appears when the
system is used at extremely
high or low temperatures or
when abnormal voltage exists.
Once these conditions are cor-
rected, the system will recover
from the temporary stop condi-
tion and the indicator will disap-
pear.
If the indicator remains dis-
played for a prolonged time,
have the system inspected at a
Toyota dealer.

■System temporary stops
due to reduced radar sensi-
tivity
This display appears when the
detectability of the radar sen-
sors is reduced. Once the condi-
tion is corrected, the system will
recover from the temporary stop
condition and the indicator will
disappear.
If the indicator remains dis-
played for a prolonged time,
have the system inspected at a
Toyota dealer.

tem. Contact a Toyota dealer
and have the system inspected.
