CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended to assist
the driver in avoiding collisions through the process of LOOK-JUDGE-ACT.
There are limits to the degree of assistance the system can provide, so please keep
in mind the following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the
vehicle, and only within a lim ited range. It is not a mechanism that allows careless
or inattentive driving, and it is not a system that can assist the driver in low-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
When attempting to estimate the likelihood of a collision, the only data available
to the pre-collision system is that from ob stacles it has detected directly in front of
the vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant
and to determine whether or not there is a possibility of collision in any given situ-
ation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help reduce the
severity of a collision, and so only acts wh en the system has judged that a collision
is unavoidable. This system by itself is not capable of automatically avoiding a col-
lision or bringing the vehicle to a stop sa fely. For this reason, when encountering a
dangerous situation the driver must take direct and immediate action in order to
ensure the safety of all involved.
NOTICE
■Precautions for cleaning the driver monitor sensor
●Gently wipe the sensor with a soft cloth to prevent damage.
●Wipe any excess dirt with a cloth dampen ed with neutral detergent, all liquids
having been wringed out of the cloth. After that, wipe again with a dry cloth.
●Do not use benzene, thinner, glass cleaners, wax, etc.

BSM (Blind Spot Monitor)
: If equipped
The Blind Spot Monitor is a system th at assists the driver to confirm
safety when changing lanes.
The system uses radar sensors to detect 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 view 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 sp ot, 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 im pact, 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.

ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immedi-
ately after is pressed.
■Humidity sensor
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunn els or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicl e interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
A sensor, which detects humidity inside the
vehicle and the temperature of the wind-
shield, is provided to detect fog on the front
windscreen. Due to the sensor, when auto-
matic mode is set the air conditioning may
make the following controls:
●Changing the amount of air flow
●Changing the amount of air introduced from
outside when in outside air mode with the air
vents in the position
●Changing the settings of the air vents to
