vehicle.
RCTA buzzer (RCTA function only)
If a vehicle approaching from the right or
left at the rear of the vehicle is detected, a
buzzer will sound. The buzzer also sounds
for approximately 1 second immediately
after the BSM main swit ch is operated to
turn the system on.
■Outside rear view mirror indicator visi-
bility
In strong sunlight, the outside rear view mir-
ror indicator may be difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear
over loud noises, such as if the audio system
volume is high.
■When “Blind Spot Monitor Unavailable”
is shown on the multi-information dis-
play
Ice, snow, mud, etc., may be attached to the
rear bumper around the sensors. ( P.183)
The system should return to normal opera-

WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are installed
behind the left and right sides of the rear
bumper respectively. Observe the fol-
lowing to ensure the Blind Spot Monitor
can function correctly.
●Keep the sensors and the surrounding
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.290) will be displayed. In this sit-
uation, clear off the dirt or snow and
drive the vehicle with the operation
conditions of the BSM function
(  P.185) satisfied for approximately
10 minutes. If the warning message
does not disappear, have the vehicle
inspected by your Lexus dealer.
●Do not subject a sensor or its sur-
rounding 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 cor-
rectly.
In the following situations, have your
vehicle inspected by your Lexus
dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of them
has become disconnected.
●Do not disassemble the sensor.

The BSM function uses radar sensors to detect the following vehicles traveling in
adjacent lanes and advises the driver of th e presence of such vehicles via the indi-
cators on the outside rear view mirrors.
WARNING
●Do not attach stickers to the sensor or
surrounding area on the rear bumper.
●Do not modify the sensor or surround-
ing area on the rear bumper.
●Do not paint the rear bumper any
color other than an official Lexus color.
■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
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 rap-
idly from behind into a blind spot. Do not
overly rely on the BSM function. 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 correctly
under certain conditions, the driver’s own
visual confirmation of safety is necessary.
The RCTA function is only a supplemen-
tary function which alerts the driver that a
vehicle is approaching from the right or
left at the rear of the vehicle. As the
RCTA function may not function cor-
rectly under certain conditions, the
driver’s own visual confirmation of safety
is necessary. Over reli ance on this func-
tion may lead to an accident resulting
death or serious injury.

The areas that vehicles can be detected in are outlined below.
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*1
Approximately 3.3 ft. (1 m) forward of the rear bumper

*1: The area between the side of the vehicle and 1.6 ft. (0.5 m) from the side of the vehicle
cannot be detected.
*2: 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 indi-
cator to illuminate or flash.
