■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.249) will be displayed. In this situ- ation, clear off the dirt or snow and
drive the vehicle with the operation conditions of the BSM function ( P.255) satisfied for approximately
10 minutes. If the warning message does not disappear, have the vehicle inspected by any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.

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 any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
• 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.

cators on the outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are not visible
using the outside rear view mirrors (the blind spots)
■BSM function detection areas
The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of the vehicle*1
Approximately 1 m (3.3 ft.) forward of the rear bumper
Approximately 3 m (9.8 ft.) from the rear bumper
Approximately 3 m (9.8 ft.) to 60 m (197 ft.) from the rear bumper*2

weather, such as heavy rain, snow, or fog • When multiple vehicles are approaching with only a small gap between each vehi-
cle • When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the vehi-cle that enters the detection area
• When the difference in speed between your vehicle and another vehicle is changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle • As your vehicle starts from a stop, a vehi-cle remains in the detection area
• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive 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.
