Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety 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-crash safety system can function effec-
tively. 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 dam-
age 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 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, grille cover or surrounding
area.
Do not modify or paint the sensor and grille cover.
Do not replace them with non-genuine parts.
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety 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 pro-
vide, so please keep in mind the following important points.
Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in front of
the vehicle, and only within a limited 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-visibility conditions. It is still necessary for the driver to pay close
attention to the vehicle’s surroundings.
Assisting the driver in making correct judgment
When attempting to estimate the possibility of a collision, the only data avail-
able to the pre-crash safety system is that from obstacles 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 situation.
Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce
the severity of a collision, and so only acts when the system has judged that a
collision is unavoidable. This system by itself is not capable of automatically
avoiding a collision or bringing the vehicle to a stop safely. 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.

CAUTION
Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the
vehicle rear bumper respectively. Observe the following to ensure the Blind
Spot Monitor 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 mal-
function 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 quali-
fied and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor or surrounding area on the

The Blind Spot Monitor function uses radar sensors to detect vehicles that
are traveling in an adjacent lane in the area that is not reflected in the out-
side rear view mirror (the blind spot), and advises the driver of the vehi-
cles 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.) for-
ward of the rear bumper

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.

The Rear Crossing Traffic Alert functions when your vehicle is in
reverse. It can detect other vehicles approaching from the right or left rear
of the vehicle. It uses radar sensors to alert the driver of the other vehi-
cle’s existence through flashing the outside rear view mirror indicators
and sounding a buzzer.

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 Rear Traffic Alert function is only an assist and is not a replacement for
careful driving. Driver must be careful when backing up, even when using Rear
Traffic Alert function. The driver’s own visual confirmation of behind you and
your vehicle is necessary and be sure there are no pedestrians, other vehicles
etc. before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.

NOTICE
Cleaning detergents
Do not use the following types of detergent, as they may discolor the vehicle
interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline, alka-
line or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
Do not use polish wax or polish cleaner. The instrument panel’s or other inte-

Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
Remove any dust or dirt from leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time. Park
the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats up
significantly.
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
When cleaning the inside of the windshield (vehicles with LDA [Lane Depar-
ture Alert])
Be careful not to touch the camera sensor (P. 264).
If the camera is accidentally scratched or hit, LDA may not operate properly or
may cause a malfunction.
Cleaning the inside of the rear window
