CAUTION
Child restraint precautions
For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute for a child restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle’s interior. This may
cause death or serious injury to the child in the event of a sudden stop, sudden
swerve or accident.
Lexus strongly urges the use of a proper child restraint system that conforms
to the size of the child, installed on the rear seat. According to accident statis-
tics, the child is safer when properly restrained in the rear seat than in the
front seat.
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 5 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front passen-
ger seat only when it is unavoidable. A child restraint system that requires a
top tether strap should not be used in the front passenger seat since there is no
top tether strap anchor for the front passenger seat. Adjust the seatback as
upright as possible and always move the seat as far back as possible because
the front passenger airbag could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously injured.
Do not allow the child to lean his/her head or any part of his/her body against
the door or the area of the seat, front, center and rear pillars or roof side rails
from which the SRS side airbags or SRS curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the SRS side
airbags and curtain shield airbags inflate, and the impact could cause death or
serious injury to the child.
Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If it is
not secured properly, it may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or accident.

Pre-crash warning
When a high possibility of a fron-
tal collision is detected, the pre-
crash safety system warning light
flashes, a buzzer sounds and a
message is shown on the multi-
information display to urge the
driver to take evasive action.
Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed. The system may not warn the driver using a warn-
ing light, warning display and buzzer when the system detects and
judges braking operations.
Pre-crash braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.
Suspension control (vehicles with Adaptive Variable Suspension Sys-
tem)
PCS (Pre-Crash Safety system)
: If equipped
When the radar sensor detects the possibility of a frontal collision, brakes
are automatically engaged to lessen impact as well as vehicle damage.
The pre-crash safety system can be turned on and off as necessary by
operating the switch. (P. 301)

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.

Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the continu-
ally changing position of the antenna, differences in signal strength and sur-
rounding objects, such as trains, transmitters, etc.
The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.
Traffic announcement operation
When traffic announcement is set to on, “TP” will appear on the screen and the
radio will begin seeking a TP station. If the radio seeks out a TP station, the pro-
gram name will appear on the screen. If a traffic announcement station is
received, the radio will be switched to the traffic information program automati-
cally. When the program ends, the initial operation will resume.
