4-5. Using the driving support systems
The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a
collision is imminent based on the
position, speed, and heading of the
obstacles.
The driver monitor sensor detects
the direction the driver is facing and
whether the driver’s eyes are open
or closed.
The system determines whether the
driver is facing forward and whether
or not the driver’s eyes are closed.

CAUTION
■Limitations of the pre-collision system
Do not overly rely on the pre-collision system. Always drive safely, taking care to
observe your surroundings and checking for any obstacles or other road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.
■Determining the direction the driver is fa cing and whether the driver’s eyes are
open or closed
The direction the driver is facing and whether the driver’s eyes are open or closed
may not be determined correctly if the following conditions exist:
●There is an object between the driver monitor sensor and the driver’s face, such
as when the sensor is blocked.
●A part of the driver’s face is covered.
●The sensor or the driver’s face is exposed to intense light such as sunlight.
●The driving posture is improper.

BSM (Blind Spot Monitor)∗
∗: If equipped
The Blind Spot Monitor is a system that assists the driver to confirm
safety when changing lanes.
The system uses radar sensors to d etect vehicles 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 vi ew mirror indicator.
BSM main switch
Pressing the switch turns the system on or off. When the switch is set to on, the
switch’s indicator illuminates.
Outside rear view mirror indicator
When a vehicle is detected in the blind spot, the outside rear view mirror indica-
tor on that side illuminates. If the turn signal lever is operated when a vehicle is in
the blind spot, the outside rear view mirror indicator flashes.

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 is a supplementary system which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor
system. The system cannot judge if it is safe to change lanes, therefore over reli-
ance 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.
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the vehi-
cle rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor system can function correctly.
●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 sur-
rounding area is subject to a strong impact, always have the area inspected by
your Lexus dealer.
●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.
●Keep the sensor and its surrounding area
on the bumper clean at all times.
