●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends
(trailers with no load on board,
etc.)
●Motorcycles traveling in the same
lane

the surrounding vehicles hinders
the detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load
in the luggage compartment, etc.)
●Preceding vehicle has an
extremely high ground clearance
●When the vehicle is towing a
trailer or during emergency tow-
ing.
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit
up to 4 in. (101 mm), including tire
height. Aftermarket lift kits may
degrade system performance.
■Conditions under which the
vehicle-to-vehic le distance con-
trol mode may not function cor-
rectly
In the case of the following condi-
tions, operate the brake pedal (or
accelerator pedal, depending on the
situation) as necessary.
As the sensor may not be able to
correctly detect vehicles ahead, the
system may not operate properly.
●When the road curves or when the
lanes are narrow
●When steering wheel operation or
your position in the lane is unsta-
ble
●When the vehicle ahead of you
decelerates suddenly
●When driving on a road sur-
rounded by a structure, such as in
a tunnel or on a bridge
●While the vehicle speed is
decreasing to the set speed after
the vehicle accelerates by
depressing the accelerator pedal
●When your vehicles is towing a

trailer or another vehicle, except
when the followin g condition is
met.
• When the other vehicle is a trailer properly attached and connected
to Toyota’s official TBC ECU.
( P.181)
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), including tire
height. Aftermarket lift kits may
degrade system performance.
BSM (Blind Spot Moni-
tor)
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver for
lane changing decision.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary 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 Blind Spot
Monitor. As the function cannot
judge if it is safe to change lanes,
over reliance could lead to an
accident resulting in death or seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.

■Setting the trailer type
Use the meter control switches

1 Press or to select .
WARNING
●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.268) will
be displayed. In this situation,
clear off the dirt or snow and drive
the vehicle with the operation con-
ditions of the BSM function
(  P.272) satisfied for approxi-
mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.
●Do not attach accessories,
stickers (including transparent
stickers), aluminum tape, etc.,
to a sensor or its surrounding
area on the rear bumper.
●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.
• If the surrounding area of a sen- sor is scratched or dented, or
part of them h as become dis-
connected.
●Do not disassemble the sensor.
●Do not modify the sensor or sur-
rounding area on the rear
bumper.
●If a sensor or the rear bumper
needs to be removed/installed
or replaced, contact your Toyota
dealer.
●Do not paint the rear bumper
any color other t han an official
Toyota color.

■Auto Trailer Detection (ATD)
Auto Trailer Detect ion (ATD) detects
if a trailer is attached by using the
Trailer Brake Controller (TBC) or the
Blind Spot Monitor (BSM) sensors.
●Trailers that use TBC can be
detected by using the 7-pin trailer
brake connectors.
●Other types of trailers can be
detected using the BSM sensors.
●When a trailer is detected via BSM
or TBC, RCTA function will be dis-
abled.
●As soon as the tra iler is detected,
the detectio n area will be
extended to a maximum length of
approximately 16 ft. (15 m) from
the rear bumper of the truck.
●If the trailer does not have a 7-pin
connector, or the 7-pin connector
is not engaged, the trailer is
detected via the BSM sensor. In
this case PKSB and Intuitive park-
ing assist functi ons will not be dis-
abled.
●For trailer auto detection without engagement of 7-pin connector,
the vehicle should be moving for-
ward at speed of above 0.6 mph
(1 km/h) for at l
east 10 seconds.
●ATD function is triggered at every
power switch on/of f cycle or if the
vehicle is stopped in shift the shift
lever is in P or N for more than 90
seconds.
●Trailer detection vis BSM sensors
may be delayed if the vehicle is in
a crowded environment such as
busy parking lot, area surrounded
with trees (camping ground) or in
an environment with objects in the
immediate environment that pre-
vent sensors from sufficiently
detecting the trailer.
■Trailer Length Detection (TLD)
●Once a trailer is detected and if
the trailer length in the meter is
selected as “Auto”, the TLD func-
tion will estimate the trailer length
using the Blind Spot Monitor sen-
sors.
In order to estimate the trailer length
with TLD function and detection
area, make at least two 90 degree
turns.
If the trailer length is entered manu-
ally via multi-information display
input, the detection area is also
adjusted to exceed the length of the
trailer.
●Depending on some trailer types
and the dimensions of the trailer
TMW performance may be
degraded.
■Vehicles that can be detected by the Blind Spot Monitor
The Blind Spot Monitor uses rear side radar sensors to detect the fol-
lowing vehicles traveling in adjacent lanes and advises the dri ver of
the presence of such vehicles v ia the indicators on the outside rear
view mirrors.

of the vehicle cannot be detected.
*2: The outer mirror indicator warning may be delayed. The delay i ncreases
in proportion to the speed differential with vehicles approaching in the
adjacent lane.
*3: The system does not support trailers wider than 8.5 ft. (2.59 m) and/or
longer than 39 ft. (12.0 m). For box trailers and certain other trailer types
that are up to 8.5 ft. (2.59 m) wide and/or 39 ft. (12.0 m) lon g, the indica-
tor warning in t he outer mirror may be de layed if the vehicle in the adja-
cent lane overtakes your vehicle at a high-speed differential.
