BSM (Blind Spot Monitor)
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 in confirm-
ing safety when changing lanes.
WARNING
QCautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always drive safely, taking care
to observe your surroundings.
The Blind Spot Monitor is a supplemen-
tary 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 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 serious
injury.
As the system may not function correctly
under certain conditions, the driver’s
own visual confirmation of safety is nec-
essary.

QIf “Parking Assist Unavailable” is dis-
played on the multi-information display
OWater may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
OInitialization may not have been per-
formed after a 12-volt battery terminal
was disconnected and reconnected. Ini-
tialize the system. (P.225)
If this message continues to be displayed
even after initialization, have the vehicle
inspected by your Lexus dealer.
QIf a 12-volt battery terminal has been
disconnected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
Additionally, for vehicles with the Parking
Support Brake function, turn the steering
wheel fully to the left and right with the vehi-
cle stopped.
QSensor detection information
OThe sensor’s detection areas are limited
to the areas around the vehicle’s front
and rear bumpers.
OThe following situations may occur
during use.
• Depending on the shape of the object and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
QObjects which the system may not prop-
erly detect
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
OWires, fences, ropes, etc.
OCotton, snow and other materials that
absorb sound waves
OSharply-angled objects
OLow objects
OTall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be detected if they are
wearing certain types of clothing.
QSituations in which the system may not
operate properly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
OThere is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
OA sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
OWhen a sensor or the area around a sen-
sor is extremely hot or cold.
OOn an extremely bumpy road, on an
incline, on gravel, or on grass.
OWhen vehicle horns, vehicle detectors,
motorcycle engines, air brakes of large
vehicles, the clearance sonar of other

to the ground, not perpendicular to the
vehicle traveling direction, uneven, or
waving are in the detection range.
OStrong wind is blowing.
OWhen driving in inclement weather such
as fog, snow or a sandstorm.
OWhen an object that cannot be detected
is between the vehicle and a detected
object.
OIf an object such as a vehicle, motorcycle,
bicycle or pedestrian cuts in front of the
vehicle or runs out from the side of the
vehicle.
OIf the orientation of a sensor has been
changed due to a collision or other
impact.
