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.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.
●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 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.
●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.

■Operation of the BSM function
The BSM function uses radar sensors to detect the following vehicles traveling in
adjacent lanes and advises the driver of the presence of such vehicles via the indi-
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
*1: The area between the side of the vehicle and 0.5 m (1.6 ft.) 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.
■The BSM function is operational when
The BSM function is operational when all of
the following conditions are met:
●The BSM function is on.
●The shift position is in a position other than R.
●The vehicle speed is greater than approx-imately 16 km/h (10 mph).
■The BSM function will detect a vehicle
when
The BSM function will detect a vehicle pres-
ent in the detection area in the following sit- uations:
●A vehicle in an adjacent lane overtakes your vehicle.
●Another vehicle enters the detection area when it changes lanes.
■Conditions under wh ich the BSM func- tion will not detect a vehicle
The BSM function is not designed to detect the following types of vehicles and/or
objects:
●Small motorcycles, bicycles, pedestrians,
etc.*
●Vehicles traveling in the opposite direc- tion
●Guardrails, walls, signs, parked vehicles
and similar stationary objects*
●Following vehicles that are in the same
lane*
●Vehicles traveling 2 lanes away from your
vehicle*
*: Depending on the conditions, detection
of a vehicle and/or object may occur.
■Conditions under wh ich the BSM func- tion may not function correctly
●The BSM function may not detect vehi-
cles correctly in the following situations: • When the sensor is misaligned due to a strong impact to the sensor or its sur-
rounding area • When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area
on the rear bumper • When driving on a road surface that is wet with standing water during bad
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.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces• When vehicle lanes are wide, or when
driving on the edge of a lane, and the vehicle in an adjacent lane is far away from your vehicle
• When an accessory (such as a bicycle carrier) or towing eyelet is installed to the rear of the vehicle
• When there is a significant difference in height between your vehicle and the vehicle that enters the detection area
• Immediately after the BSM function is turned on
●Instances of the BSM function unneces-sarily detecting a vehicle and/or object may increase in the following situations:

• When the sensor is misaligned due to a strong impact to the sensor or its sur-rounding area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the detection area is short
• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehi-cle traveling in a lane other than the adja-
cent lanes enters the detection area • When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When the tires are slipping or spinning • When the distance between your vehicle and a following vehicle is short
• When an accessory (such as a bicycle carrier) or towing eyelet is installed to the rear of the vehicle
■Operation of the RCTA function
The RCTA function uses radar sensors to detect vehicles approaching from the
right or left at the rear of the vehicle and alerts the driver of the presence of such
vehicles by flashing the outside rear view mirror indicators and sounding a buzzer.

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.

■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care

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

Active rear wing*
The vehicle is equipped with an
active rear wing that operates auto-
matically while the vehicle is being
driven. This active rear wing
enhances aerodynamic perfor-
mance, especially at high speeds,
contributing to a more stable ride.
The active rear wing can be con-
trolled manually using a switch.

Or, begin driving the vehicle and the active rear wing will raise automatically when the vehicle speed reaches 25 km/h (16 mph).
■When there is a malfunction in the sys-
tem
A warning message will be displayed on the
multi-information display. ( P.378)
■Customization
The active rear wing can be turned on/ off.
(Customizable features: P.423)
The active rear wing will operate auto-
matically at the following speeds
according to the selected driving
mode ( P.242).
(Always observe the legal speed limit
when driving on public roads.)
 When other than Eco drive mode is
selected
