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 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-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 possibility of a collision, the only data available
to the pre-collision 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 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 when 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 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.
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 dampened 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.

CAUTION
■Handling the radar sensor
●Keep the sensor and its surrounding area on the bumper clean at all times.
●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.

Driving
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-
cle’s 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 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the side of
the vehicle is not in the detection area
Approximately 9.8 ft. (3 m) from
the rear bumper
Approximately 3.3 ft. (1 m) for-
ward of the rear bumper

The Rear Cross 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 vehicle’s exist-
ence through flashing the outside rear view mirror indicators and sound-
ing 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 Cross Traffic Alert function is only an assist and is not a replacement for
careful driving. The driver must be careful when backing up, even when using the
Rear Cross 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 vehi-
cles 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.

■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the engine switch to
IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will auto-
matically be registered to the electronic key that was used to unlock the vehicle.
The system may not operate correctly if more than one electronic key is in the vicinity
or if the smart access system with push-button start is used to unlock a passenger
door.
Settings for the electronic key and the corresponding door can be changed. Contact
your Lexus dealer.
■Using automatic mode
●Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow imme-
diately after is pressed.
●Cool air may blow around the upper body even when the heater is on due to sun-
light.
■Humidity sensor
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
