CAUTION
Handling the radar sensor
Keep the sensor and its surrounding area on the bumper clean at all times.
Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may
malfunction and vehicles that enter the detection area may not be
detected. If the sensor or surrounding area is subject to a strong impact,
always have the area inspected by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
Do not modify the sensor or surrounding area on the bumper.
Do not paint the sensor or surrounding area on the bumper.
One Blind Spot Monitor sensor is
installed inside the left and right side of

The Blind Spot Monitor function uses radar sensors to detect vehi-
cles that are traveling in an adjacent lane in the area that is not
reflected in the outside rear view mirror (the blind spot), and
advises the driver of the vehicle’s existence via the outside rear
view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 3.5 m (11.5 ft.)
from the side of the vehicle
The first 0.5 m (1.6 ft.) from the
side of the vehicle is not in the
detection area
Approximately 3 m (9.8 ft.)
from the rear bumper
Approximately 1 m (3.3 ft.)

The Blind Spot Monitor function is operational when
The BSM main switch is set to on
Vehicle speed is greater than approximately 16 km/h (10 mph).
The Blind Spot Monitor function will detect a vehicle when
A vehicle in an adjacent lane overtakes your vehicle.
Another vehicle enters the detection area when it changes lanes.
Conditions under which the Blind Spot Monitor function will not detect a
vehicle
The Blind Spot Monitor function is not designed to detect the following
types of vehicles and/or objects:
Small motorcycles, bicycles, pedestrians etc.*
Vehicles traveling in the opposite direction
Guardrails, walls, signs, parked vehicles and similar stationary objects*
Following vehicles that are in the same lane*
Vehicles driving 2 lanes across from your vehicle*
*
: Depending on conditions, detection of a vehicle and/or object may occur.
CAUTION
Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts
the driver that a vehicle is present in the blind spot. Do not overly rely on
the Blind Spot Monitor function. The function cannot judge if it is safe to
change lanes, therefore over reliance could cause an accident resulting in
death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Conditions under which the Blind Spot Monitor function may not function
correctly
The Blind Spot Monitor function may not detect vehicles correctly in the
following conditions:
• During bad weather such as heavy rain, fog, snow etc.
• When ice or mud etc. is attached to the rear bumper
• When driving on a road surface that is wet due to rain, standing water
etc.
• When there is a significant difference in speed between your vehicle and
the vehicle that enters the detection area
• When a vehicle is in the detection area from a stop and remains in the
detection area as your vehicle accelerates
• When driving up or down consecutive steep inclines, such as hills, a dip
in the road etc.
• When multiple vehicles approach with only a small gap between each
vehicle
• When vehicle lanes are wide, and the vehicle in the next lane is too far
away from your vehicle
• When the vehicle that enters the detection area is traveling at about the
same speed as your vehicle
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Directly after the BSM main switch is set to on
• When your vehicle is towing a trailer
Instances of the Blind Spot Monitor function unnecessarily detecting a
vehicle and/ or object may increase under the following conditions:
• When there is only a short distance between your vehicle and a guardrail,
wall etc.
• When there is only a short distance between your vehicle and a following
vehicle
• When vehicle lanes are narrow and a vehicle driving 2 lanes across from

own visual confirmation of behind you and your vehicle is necessary and
be sure there are no pedestrians, other vehicles etc. before backing up. Fail-
ure to do so could cause death or serious injury.
